Crystal structure of the Candida albicans Kar3 kinesin motor domain fused to maltose-binding protein  

SciTech Connect

Highlights: Black-Right-Pointing-Pointer The Candida albicans Kar3 motor domain structure was solved as a maltose-binding protein fusion. Black-Right-Pointing-Pointer The electrostatic surface and part of the ATPase pocket of the motor domain differs markedly from other kinesins. Black-Right-Pointing-Pointer The MBP-Kar3 interface highlights a new site for intramolecular or intermolecular interactions. -- Abstract: In the human fungal pathogen Candida albicans, the Kinesin-14 motor protein Kar3 (CaKar3) is critical for normal mitotic division, nuclear fusion during mating, and morphogenic transition from the commensal yeast form to the virulent hyphal form. As a first step towards detailed characterization of this motor of potential medical significance, we have crystallized and determined the X-ray structure of the motor domain of CaKar3 as a maltose-binding protein (MBP) fusion. The structure shows strong conservation of overall motor domain topology to other Kar3 kinesins, but with some prominent differences in one of the motifs that compose the nucleotide-binding pocket and the surface charge distribution. The MBP and Kar3 modules are arranged such that MBP interacts with the Kar3 motor domain core at the same site where the neck linker of conventional kinesins docks during the 'ATP state' of the mechanochemical cycle. This site differs from the Kar3 neck-core interface in the recent structure of the ScKar3Vik1 heterodimer. The position of MBP is also completely distinct from the Vik1 subunit in this complex. This may suggest that the site of MBP interaction on the CaKar3 motor domain provides an interface for the neck, or perhaps a partner subunit, at an intermediate state of its motile cycle that has not yet been observed for Kinesin-14 motors.

Motor current signature analysis method for diagnosing motor operated devices  

DOE Patents (OSTI)

A motor current noise signature analysis method and apparatus for remotely monitoring the operating characteristics of an electric motor-operated device such as a motor-operated valve. Frequency domain signal analysis techniques are applied to a conditioned motor current signal to distinctly identify various operating parameters of the motor driven device from the motor current signature. The signature may be recorded and compared with subsequent signatures to detect operating abnormalities and degradation of the device. This diagnostic method does not require special equipment to be installed on the motor-operated device, and the current sensing may be performed at remote control locations, e.g., where the motor-operated devices are used in accessible or hostile environments.

Advanced Motors  

SciTech Connect

Project Summary Transportation energy usage is predicted to increase substantially by 2020. Hybrid vehicles and fuel cell powered vehicles are destined to become more prominent as fuel prices rise with the demand. Hybrid and fuel cell vehicle platforms are both dependent on high performance electric motors. Electric motors for transportation duty will require sizeable low-speed torque to accelerate the vehicle. As motor speed increases, the torque requirement decreases which results in a nearly constant power motor output. Interior permanent magnet synchronous motors (IPMSM) are well suited for this duty. , , These rotor geometries are configured in straight lines and semi circular arc shapes. These designs are of limited configurations because of the lack of availability of permanent magnets of any other shapes at present. We propose to fabricate rotors via a novel processing approach where we start with magnet powders and compact them into a net shape rotor in a single step. Using this approach, widely different rotor designs can be implemented for efficiency. The current limitation on magnet shape and thickness will be eliminated. This is accomplished by co-filling magnet and soft iron powders at specified locations in intricate shapes using specially designed dies and automatic powder filling station. The process fundamentals for accomplishing occurred under a previous Applied Technology Program titled, ???????????????¢????????????????????????????????Motors and Generators for the 21st Century???????????????¢???????????????????????????????. New efficient motor designs that are not currently possible (or cost prohibitive) can be accomplished by this approach. Such an approach to motor fabrication opens up a new dimension in motor design. Feasibility Results We were able to optimize a IPMSM rotor to take advantage of the powder co-filling and DMC compaction processing methods. The minimum low speed torque requirement of 5 N-m can be met through an optimized design with magnet material having a Br capability of 0.2 T. This level of magnetic performance can be met with a variety of bonded magnet compositions. The torque ripple was found to drop significantly by using thinner magnet segments. The powder co-filling and subsequent compaction processing allow for thinner magnet structures to be formed. Torque ripple can be further reduced by using skewing and pole shaping techniques. The techniques can be incorporated into the rotor during the powder co-filling process.

Motor current signature analysis for determining operational readiness of motor-operated valves (MOVs)  

SciTech Connect

Motor current signature analysis (MCSA) is a novel diagnostic process for condition monitoring of electric-motor-driven mechanical equipment (e.g., pumps, motor-operated valves, compressors, and processing machinery). The MCSA process identifies, characterizes, and trends over time the instantaneous load variations of mechanical equipment in order to diagnose changes in the condition of the equipment (e.g., due to degradation or service wear), which, if allowed to continue, may lead to failure. It monitors the instantaneous variations (noise content) in the electric current flowing through the power leads to the electric motor that drives the equipment. The motor itself thereby acts as a transducer, sensing both large and small, long-term and rapid, mechanical load variations and converting them to variations in the induced current generated in the motor windings. This motor current noise signature is detected, amplified, and further processed as needed to examine its time domain and frequency domain (spectral) characteristics. The operational principles of MCSA and the nonintrusive data collection apparatus and procedure used with MOVs will be described. Data collected from MOVs in both laboratory and in-plant environments will also be shown to illustrate the ability of MCSA to ''see'' the detailed inner workings of the valve and operator and thus to detect degraded performance at an incipient stage.

High-frequency equivalent model of AC motor for electric vehicle drive system  

Science Journals Connector (OSTI)

The application of the motor drive system in electric and hybrid-electric vehicles can lead to a significant increase in electromagnetic compatibility. The AC motor as an important part of motor drive system must be considered. In this paper, a high frequency modelling method of the AC motor is presented. The modelling method consists of deriving the motor model parameters from mathematical resolution of the electrical circuit equations and observation of the variations of the motor impedance with the frequency. All parameters of the proposed models are obtained by differential mode (DM) and common mode (CM) impedance measurement in the frequency domain. The model is verified by impedance measurement of a synchronous motor. The method proposed can be used to obtain a high-frequency equivalent circuit of an AC motor and predict conducted electromagnetic interference in a motor drive system.

Artificial Brownian motors: Controlling transport on the nanoscale  

Science Journals Connector (OSTI)

In systems possessing spatial or dynamical symmetry breaking, Brownian motion combined with unbiased external input signals, deterministic and random alike, can assist directed motion of particles at submicron scales. In such cases, one speaks of Brownian motors. In this review the constructive role of Brownian motion is exemplified for various physical and technological setups, which are inspired by the cellular molecular machinery: the working principles and characteristics of stylized devices are discussed to show how fluctuations, either thermal or extrinsic, can be used to control diffusive particle transport. Recent experimental demonstrations of this concept are surveyed with particular attention to transport in artificial, i.e., nonbiological, nanopores, lithographic tracks, and optical traps, where single-particle currents were first measured. Much emphasis is given to two- and three-dimensional devices containing many interacting particles of one or more species; for this class of artificial motors, noise rectification results also from the interplay of particle Brownian motion and geometric constraints. Recently, selective control and optimization of the transport of interacting colloidal particles and magnetic vortices have been successfully achieved, thus leading to the new generation of microfluidic and superconducting devices presented here. The field has recently been enriched with impressive experimental achievements in building artificial Brownian motor devices that even operate within the quantum domain by harvesting quantum Brownian motion. Sundry akin topics include activities aimed at noise-assisted shuttling other degrees of freedom such as charge, spin, or even heat and the assembly of chemical synthetic molecular motors. This review ends with a perspective for future pathways and potential new applications.

Adaptive wavelet transform for vibration signal modelling and application in fault diagnosis of water hydraulic motor  

Science Journals Connector (OSTI)

There has been an increasing application of water hydraulics in industries due to growing concern on the environmental, health and safety issues. The fault diagnosis of water hydraulic motor is important for improving water hydraulic system reliability and performance. In this paper, fault diagnosis of water hydraulic motor in water hydraulic system is investigated based on adaptive wavelet analysis. A novel method for modelling the vibration signal based on the adaptive wavelet transform (AWT) is proposed. The linear combination of wavelets is introduced as wavelet itself and adapted for the particular vibration signal, which goes beyond adapting parameters of a fixed-shape wavelet. The AWT procedure based on the parametric optimisation by genetic algorithm (GA) is developed. The model-based method by AWT is applied to extract the features in the fault diagnosis of the water hydraulic motor. This technique for de-noising the corrupted simulation signal shows that it can improve the signal-to-noise ratio of the vibration signal. The results of the experimental signal demonstrate the characteristic vibration signal details in fine resolution. The magnitude plots of the continuous wavelet transform (CWT) show the characteristic signal's energy in time and frequency domain which can be used as feature values for fault diagnosis of water hydraulic motor.

Development of Ulta-Efficient Electric Motors  

SciTech Connect

Electric motors utilize a large amount of electrical energy in utility and industrial applications. Electric motors constructed with high temperature superconducting (HTS) materials have the potential to dramatically reduce electric motor size and losses. HTS motors are best suited for large motor applications at ratings above 1000 horsepower (hp), where the energy savings from the efficiency improvement can overcome the additional power required to keep the superconductors on the rotor cooled. Large HTS based motors are expected to be half the volume and have half the losses of conventional induction motors of the same rating. For a 5000 hp industrial motor, this energy savings can result in $50,000 in operating cost savings over the course of a single year of operation. Since large horsepower motors utilize (or convert) about 30% of the electrical power generated in the United States and about 70% of large motors are candidates for replacement by HTS motors, the annual energy savings potential through the utilization of HTS motors can be up to $1 Billion in the United States alone. Research in the application of HTS materials to electric motors has lead to a number of HTS motor prototypes yet no industrial HTS motor product has yet been introduced. These motor demonstrations have been synchronous motors with HTS field windings, on the rotor. Figure 1-1 shows a solid model rendering of this type of motor. The rotor winding is made with HTS coils that are held at cryogenic temperature by introducing cooling fluid from the cryocooler to the rotor through a transfer coupling. The stator winding is made of copper wire. The HTS winding is thermally isolated from the warm armature and motor shafts by a vacuum insulation space and through the use of composite torque tubes. The stator in Figure 1-1 is an air core stator in that the stator teeth and a small part of the yoke is made up of nonmagnetic material so the magnetic fields distribute themselves as if in air. Between the HTS field winding and the physical air gap is a series of concentric cylinders that act as vacuum insulation space walls as well as conducting paths for induced currents to flow in order to shield the HTS winding and the rotor cold space from time dependent fields. These time dependent fields may be caused by rotor hunting, during a change in motor load, or by non-fundamental component voltages and currents applied by the inverter. These motors are variable speed controlled by the inverter. Common large motor utility and industrial applications are pump and fan drives that are best suited by a variable speed motor. Inverter control of the HTS motor eliminates the need to design the rotor for line starting, which would dump a large amount of heat into the rotor that would then heavily tax the cryogenic cooling system. The field winding is fed by a brushless exciter that provides DC current to the HTS rotor winding. The stator winding is air or water cooled. Technical and commercial hurdles to industrial HTS motor product introduction and customer acceptance include (1) the high cost of HTS wire and the cryogenic cooling system components, (2) customer concerns about reliability of HTS motors, and (3) the ability to attain the loss reduction potential of large HTS motors. Reliance Electric has demonstrated a number of HTS based electric motors up to a 1000 hp, variable speed synchronous motor with an HTS field winding in the year 2000. In 2001 this motor was tested to 1600 hp with a sinusoidal (constant frequency) supply. Figure 1-2 shows the HTS motor on the dynamometer test stand in the Reliance Electric test lab. The extensive test program of the 1000 hp motor successfully demonstrated the technical feasibility of large HTS motors and the basic technologies involved, however the test results did indicate the need for design refinements. In addition, test results served to identify other more fundamental critical technology issues, and revealed the need to continue research efforts in order to improve future HTS motor first cost, reliability, and performa

Traffic of Molecular Motors  

E-Print Network (OSTI)

Molecular motors perform active movements along cytoskeletal filaments and drive the traffic of organelles and other cargo particles in cells. In contrast to the macroscopic traffic of cars, however, the traffic of molecular motors is characterized by a finite walking distance (or run length) after which a motor unbinds from the filament along which it moves. Unbound motors perform Brownian motion in the surrounding aqueous solution until they rebind to a filament. We use variants of driven lattice gas models to describe the interplay of their active movements, the unbound diffusion, and the binding/unbinding dynamics. If the motor concentration is large, motor-motor interactions become important and lead to a variety of cooperative traffic phenomena such as traffic jams on the filaments, boundary-induced phase transitions, and spontaneous symmetry breaking in systems with two species of motors. If the filament is surrounded by a large reservoir of motors, the jam length, i.e., the extension of the traffic jams is of the order of the walking distance. Much longer jams can be found in confined geometries such as tube-like compartments.

Bifurcation and control of chaos in Induction motor drives  

E-Print Network (OSTI)

The induction motor controlled by Indirect Field Oriented Control (IFOC) is known to have high performance and better stability. This paper reports the dynamical behavior of an indirect field oriented control (IFOC) induction motor drive in the light of bifurcation theory. The speed of high performance induction motor drive is controlled by IFOC method. The knowledge of qualitative change of the behavior of the motor such as equilibrium points, limit cycles and chaos with the change of motor parameters and load torque are essential for proper control of the motor. This paper provides a numerical approach to understand better the dynamical behavior of an indirect field oriented control of a current-fed induction motor. The focus is on bifurcation analysis of the IFOC motor, with a particular emphasis on the change that affects the dynamics and stability under small variations of Proportional Integral controller (PI) parameters, load torque and k, the ratio of the rotor time constant and its estimate etc. Bifurcation diagrams are computed. This paper also attempts to discuss various types of the transition to chaos in the induction motor. The results of the obtained bifurcation simulations give useful guidelines for adjusting both motor model and PI controller parameters. It is also important to ensure desired operation of the motor when the motor shows chaotic behavior. Infinite numbers of unstable periodic orbits are embedded in a chaotic attractor. Any unstable periodic orbit can be stabilized by proper control algorithm. The delayed feedback control method to control chaos has been implemented in this system.

Research on Induction Motor for Mini Electric Vehicles  

Science Journals Connector (OSTI)

The motor of a mini electric vehicle uses dozens of storage batteries as power supply, which has low voltage and large current. Therefore, the loss and temperature raise of the motor is high. In this paper, the loss of different induction motors for mini electric vehicles is calculated and the effects of rotor materials and air gap length on the performance of these motors are studied. The analyses show that the efficiency of the motor with a copper mouse cage rotor is considerably higher than that of the motor with a aluminum rotor. The temperature raise of both an air-cooling and a water-cooling induction motor is analyzed, which demonstrates that the temperature raise of the motor windings is higher than that of the other parts, and the temperature raise of the water-cooling motor is lower than that of the air-cooling motor. To verify the results of the theoretical analyses, four prototype induction motors (aluminum rotor, copper mouse cage rotor, air-cooling and spiral groove machine) have been designed and processed. The experiments to measure the efficiency and temperature raise were carried out on these motors. The experimental results prove that the theoretical analyses are correct.

New disc type switched reluctance motor for high torque density  

Science Journals Connector (OSTI)

A new disc type switched reluctance motor (DSRM) structure for high torque density is presented. The new motor has a double sided stator structure that provides higher torque and less acoustic noise than classical switched reluctance motors (SRMs) of small sizes. The motor is based on linear switched reluctance motors. The results of the analytical and numerical analysis are given to evaluate the effectiveness of the motor structure, and experimental noise measurement data are presented. In the numerical analysis, due to the highly nonlinear nature of the motor, finite element analysis is employed. A prototype 6/4 DSRM and a classical SRM are built and tested for experimental studies. The obtained test and simulation results show that the DSRM has a higher torque and less acoustic noise performance.

A method and circuitry are disclosed for sampling periodic amplitude modulations in a nonstationary periodic carrier wave to determine frequencies in the amplitude modulations. The method and circuit are described in terms of an improved motor current signature analysis. The method insures that the sampled data set contains an exact whole number of carrier wave cycles by defining the rate at which samples of motor current data are collected. The circuitry insures that a sampled data set containing stationary carrier waves is recreated from the analog motor current signal containing nonstationary carrier waves by conditioning the actual sampling rate to adjust with the frequency variations in the carrier wave. After the sampled data is transformed to the frequency domain via the Discrete Fourier Transform, the frequency distribution in the discrete spectra of those components due to the carrier wave and its harmonics will be minimized so that signals of interest are more easily analyzed. 29 figs.

Domain Walls in Gapped Graphene  

Science Journals Connector (OSTI)

The electronic properties of a particular class of domain walls in gapped graphene are investigated. We show that they can support midgap states which are localized in the vicinity of the domain wall and propagate along its length. With a finite density of domain walls, these states can alter the electronic properties of gapped graphene significantly. If the midgap band is partially filled, the domain wall can behave like a one-dimensional metal embedded in a semiconductor and could potentially be used as a single-channel quantum wire.

Domain walls in SU(5)  

Science Journals Connector (OSTI)

We consider the grand unified SU(5) model with a small or vanishing cubic term in the adjoint scalar field in the potential. This gives the model an approximate or exact Z2 symmetry whose breaking leads to domain walls. The simplest domain wall has the structure of a kink across which the Higgs field changes sign (??-?) and inside which the full SU(5) is restored. The kink is shown to be perturbatively unstable for all parameters. We then construct a domain wall solution that is lighter than the kink and show it to be perturbatively stable for a range of parameters. The symmetry in the core of this domain wall is smaller than that outside. The interactions of the domain wall with magnetic monopoles are discussed and it is shown that magnetic monopoles with certain internal space orientations relative to the wall pass through the domain wall. Magnetic monopoles in other relative internal space orientations are likely to be swept away on collision with the domain walls, suggesting a scenario where the domain walls might act like optical polarization filters, allowing certain monopole polarizations to pass through but not others. As SU(5) domain walls will also be formed at small values of the cubic coupling, this leads to a very complicated picture of the evolution of defects after the grand unified phase transition.

Retail Motor Gasoline Prices*  

Gasoline and Diesel Fuel Update (EIA)

6 6 Notes: Gasoline pump prices have backed down from the high prices experienced last summer and fall. The retail price for regular motor gasoline fell 11 cents per gallon from September to December. However, with crude oil prices rebounding somewhat from their December lows combined with lower than normal stock levels, we project that prices at the pump will rise modestly as the 2001 driving season begins this spring. For the summer of 2001, we expect only a little difference from the average price of $1.50 per gallon seen during the previous driving season, as motor gasoline stocks going into the driving season are projected to be slightly less than they were last year. The situation of relatively low inventories for gasoline could set the stage for some regional imbalances in supply that could once again

Active Diffusion of Motor Particles  

Science Journals Connector (OSTI)

The movement of motor particles consisting of one or several molecular motors bound to a cargo particle is studied theoretically. The particles move on patterns of immobilized filaments. Several patterns are described for which the motor particles undergo nondirected but enhanced diffusion. Depending on the walking distance of the particles and the mesh size of the patterns, the active diffusion coefficient exhibits three different regimes. For micrometer-sized motor particles in water, e.g., this diffusion coefficient can be enhanced by 2orders of magnitude.

Motor fuel prices in Turkey  

Science Journals Connector (OSTI)

Abstract The world?s most expensive motor fuel (gasoline, diesel and LPG) is sold most likely in the Republic of Turkey. This paper investigates the key issues related to the motor fuel prices in Turkey. First of all, the paper analyses the main reason behind high prices, namely motor fuel taxes in Turkey. Then, it estimates the elasticity of motor fuel demand in Turkey using an econometric analysis. The findings indicate that motor fuel demand in Turkey is quite inelastic and, therefore, not responsive to price increases caused by an increase in either pre-tax prices or taxes. Therefore, fuel market in Turkey is open to opportunistic behavior by firms (through excessive profits) and the government (through excessive taxes). Besides, the paper focuses on the impact of high motor fuel prices on road transport associated activities, including the pattern of passenger transportation, motorization rate, fuel use, total kilometers traveled and CO2 emissions from road transportation. The impact of motor fuel prices on income distribution in Turkey and Turkish public opinion about high motor fuel prices are also among the subjects investigated in the course of the study.

Word Domain Disambiguation via Word Sense Disambiguation  

SciTech Connect

Word subject domains have been widely used to improve the perform-ance of word sense disambiguation al-gorithms. However, comparatively little effort has been devoted so far to the disambiguation of word subject do-mains. The few existing approaches have focused on the development of al-gorithms specific to word domain dis-ambiguation. In this paper we explore an alternative approach where word domain disambiguation is achieved via word sense disambiguation. Our study shows that this approach yields very strong results, suggesting that word domain disambiguation can be ad-dressed in terms of word sense disam-biguation with no need for special purpose algorithms.

Transport of Molecular Motor Dimers in Burnt-Bridge Models  

E-Print Network (OSTI)

Dynamics of molecular motor dimers, consisting of rigidly bound particles that move along two parallel lattices and interact with underlying molecular tracks, is investigated theoretically by analyzing discrete-state stochastic continuous-time burnt-bridge models. In these models the motion of molecular motors is viewed as a random walk along the lattices with periodically distributed weak links (bridges). When the particle crosses the weak link it can be destroyed with a probability $p$, driving the molecular motor motion in one direction. Dynamic properties and effective generated forces of dimer molecular motors are calculated exactly as a function of a concentration of bridges $c$ and burning probability $p$ and compared with properties of the monomer motors. It is found that the ratio of the velocities of the dimer and the monomer can never exceed 2, while the dispersions of the dimer and the monomer are not very different. The relative effective generated force of the dimer (as compared to the monomer) also cannot be larger than 2 for most sets of parameters. However, a very large force can be produced by the dimer in the special case of $c=1/2$ for non-zero shift between the lattices. Our calculations do not show the significant increase in the force generated by collagenase motor proteins in real biological systems as predicted by previous computational studies. The observed behavior of dimer molecular motors is discussed by considering in detail the particle dynamics near burnt bridges.

Design of Efficient In-Wheel Motor for Electric Vehicles  

Science Journals Connector (OSTI)

Abstract This research paper deals with the design and development of an in-wheel motor for electric vehicles. The proposed motor generates a 350-watt power drive with a power source of two 12V batteries. The batteries are connected in series to increase the voltage to 24 volts and 18.23 A. The in-wheel motor is based on the principle of a DC electric motor to drive the vehicle wheels so that the mechanical components of the transmission and the energy loss are minimized. The proposed in-wheel motor has 46 poles, 51 slots and 51 teeth. In addition, the method lowers the maintenance cost. This research work assumes the maximum weight of 70kg and the running speed of 20km/hr. The experiment results show that the output power and efficiency of the in-wheel motor are subject to the variation in input power given that the input voltage remains constant at 25.41 volts. The maximum efficiency of the in-wheel motor of 82.56% is achieved at 2.5 N-m torque. The maximum torque of 6.25 N-m is achieved with the input power of 348.76 watts.

Submersible canned motor transfer pump  

DOE Patents (OSTI)

A transfer pump used in a waste tank for transferring high-level radioactive liquid waste from a waste tank and having a column assembly, a canned electric motor means, and an impeller assembly with an upper impeller and a lower impeller connected to a shaft of a rotor assembly. The column assembly locates a motor housing with the electric motor means adjacent to the impeller assembly which creates an hydraulic head, and which forces the liquid waste, into the motor housing to cool the electric motor means and to cool and/or lubricate the radial and thrust bearing assemblies. Hard-on-hard bearing surfaces of the bearing assemblies and a ring assembly between the upper impeller and electric motor means grind large particles in the liquid waste flow. Slots in the static bearing member of the radial bearing assemblies further grind down the solid waste particles so that only particles smaller than the clearances in the system can pass therethrough, thereby resisting damage to and the interruption of the operation of the transfer pump. The column assembly is modular so that sections can be easily assembled, disassembled and/or removed. A second embodiment employs a stator jacket which provides an alternate means for cooling the electric motor means and lubricating and/or cooling the bearing assemblies, and a third embodiment employs a variable level suction device which allows liquid waste to be drawn into the transfer pump from varying and discrete levels in the waste tank.

Fault degradation assessment of water hydraulic motor by impulse vibration signal with Wavelet Packet Analysis and KolmogorovSmirnov Test  

Science Journals Connector (OSTI)

The machinery fault diagnosis is important for improving reliability and performance of systems. Many methods such as Time Synchronous Average (TSA), Fast Fourier Transform (FFT)-based spectrum analysis and short-time Fourier transform (STFT) have been applied in fault diagnosis and condition monitoring of mechanical system. The above methods analyze the signal in frequency domain with low resolution, which is not suitable for non-stationary vibration signal. The KolmogorovSmirnov (KS) test is a simple and precise technique in vibration signal analysis for machinery fault diagnosis. It has limited use and advantage to analyze the vibration signal with higher noise directly. In this paper, a new method for the fault degradation assessment of the water hydraulic motor is proposed based on Wavelet Packet Analysis (WPA) and KS test to analyze the impulsive energy of the vibration signal, which is used to detect the piston condition of water hydraulic motor. WPA is used to analyze the impulsive vibration signal from the casing of the water hydraulic motor to obtain the impulsive energy. The impulsive energy of the vibration signal can be obtained by the multi-decomposition based on Wavelet Packet Transform (WPT) and used as feature values to assess the fault degradation of the pistons. The kurtosis of the impulsive energy in the reconstructed signal from the Wavelet Packet coefficients is used to extract the feature values of the impulse energy by calculating the coefficients of the WPT multi-decomposition. The KS test is used to compare the kurtosis of the impulse energy of the vibration signal statistically under the different piston conditions. The results show the applicability and effectiveness of the proposed method to assess the fault degradation of the pistons in the water hydraulic motor.

Finite-size domains in membranes with active two-state inclusions  

E-Print Network (OSTI)

The distribution of inclusion-rich domains in membranes with active two-state inclusions is studied by simulations. Our study shows that typical size of inclusion-rich domains ($L$) can be controlled by inclusion activities in several ways. When there is effective attraction between state-1 inclusions, we find: (i) Small domains with only several inclusions are observed for inclusions with time scales ($\\sim 10^{-3} {\\rm s}$) and interaction energy [$\\sim \\mathcal{O}({\\rm k_BT})$] comparable to motor proteins. (ii) $L$ scales as 1/3 power of the lifetime of state-1 for a wide range of parameters. (iii) $L$ shows a switch-like dependence on state-2 lifetime $k_{12}^{-1}$. That is, $L$ depends weakly on $k_{12}$ when $k_{12} k_{12}^*$, the crossover $k_{12}^*$ occurs when the diffusion length of a typical state-2 inclusion within its lifetime is comparable to $L$. (iv) Inclusion-curvature coupling provides another length scale that competes with the effects of transition rates.

Minimizing Wheel Slip in Railway Locomotives with Coupled Permanent Magnet Synchronous Motors  

E-Print Network (OSTI)

In this work I consider control strategies of permanent magnet synchronous motors in which the back-emf signal from the motor is used to achieve commutation of the six step driving circuit. I show that if the strategy is modified to connect multiple motors in a cyclic chain, then a collective synchronized state is favoured. The stability of this state can be exploited in the bogies of a railway locomotive to automatically terminate wheel slipping episodes.

A one-time opportunity to expand the market for premium efficiency motors  

SciTech Connect

A mid-Atlantic utility conducted a detailed research study on their motors market. The study showed that their motor loads come mostly from motors under 50 horsepower, and predominantly from industry. The proportion of premium-efficiency motor sales is very low relative to other areas which, unlike this utility's service territory, have a history of rebate programs. Most sales in this utility's territory are for replacement motors. Manufacturers are planning to create new lines of motors which meet the 1997 federal minimum motor-efficiency manufacturing standard, but are less efficient than premium motors. Few of these motors are on the market yet. The mandatory federal efficiency standard creates a unique, one-time situation where premium-efficiency motors will be a better-established and more familiar product among customers and vendors than less efficient motors. The utility has begun a motors rebate and technical assistance program which is intended to use this one-time opportunity to significantly expand the market for premium motors. Rebates are tied to the new Consortium for Energy Efficiency motor standards to ensure a common message to manufacturers among utilities. While the majority of premium motors available locally already meet the standard, this will encourage manufacturers to bring the rest of their offerings in line. Like many motors programs, this program will offer rebates, marketing, and technical assistance. However, the program design calls for a short-term (three year), very intense effort, including a rebate set at 100% of incremental cost, a short-term vendor bonus, and intensive marketing to large customers. Additionally, the large savings per motor in 1997 (when the baseline is inefficient standard motors) will justify a more generous payment in the first year. Many other US utility motor rebate programs have offered less generous incentives and used less intensive marketing, but have had only marginal impacts on markets (often 20--30%), or have taken many years to have an impact. This program will test the theory that it is better to strike hard at the right moment than to gnaw at the edges of a market for many years. While the program was designed for one utility, the overall approach would be more effective at working with vendors and customers if utilities joined together to sponsor a similar program with common terms and single redemption centers. This may be an option in the coming months.

Local Voltage Support from Distributed Energy Resources to Prevent Air Conditioner Motor Stalling  

SciTech Connect

Microgrid voltage collapse often happens when there is a high percentage of low inertia air-conditioning (AC) motors in the power systems. The stalling of the AC motors results in Fault Induced Delayed Voltage Recovery (FIDVR). A hybrid load model including typical building loads, AC motor loads, and other induction motor loads is built to simulate the motoring stalling phenomena. Furthermore, distributed energy resources (DE) with local voltage support capability are utilized to boost the local bus voltage during a fault, and prevent the motor stalling. The simulation results are presented. The analysis of the simulation results show that local voltage support from multiple DEs can effectively and economically solve the microgrid voltage collapse problem.

Modeling and Simulation of an Electric Scooter Driven by a Single-Phase Induction Motor  

E-Print Network (OSTI)

Abstract:- An electric vehicle driven by DC motors has been widely used for several applications. In this paper, replacement of the DC motor by a single-phase induction motor on the electric vehicle is proposed. Low cost and less maintenance make the single-phase induction motor more impressive although a complicated inverter onboard the vehicle is required. This paper investigates this possibility through a whole system of electric vehicle movement simulation. The whole system simulation consists of three main parts: 1) power supply interface 2) motor performance calculation and 3) vehicle movement simulation. The electric scooter of 0.26 kW rating was employed for test. As a result, a single-phase induction motor showed ability to drive an electric scooter carrying with 80-kg load at almost constant speed of 20 kph.

Effect of motor vibration problem on the power quality of water pumping stations  

Science Journals Connector (OSTI)

Abstract In this paper the effect of motor vibration problems on the dynamic performance and electrical power quality of water pumping stations is studied. A pump unit was tested for a full load and no load operating conditions. The dynamic results indicated that there is a problem of looseness in the motor base plate. The measurements were repeated again after achieving good support to the motor on its base plate. The results indicated that the vibration level decreased about 48% due to good support. The electrical power quality analysis showed that; the total harmonic distortion (THD) increases by about 12% due to the effect of bad motor vibration, and the 5th and 7th harmonic contents also increased by about 0.51.0%. Also the bad motor vibration caused large values of instantaneous flicker. These results indicated that the bad motor support causes many dynamics troubles and causes some power quality problems for the electrical feeder.

REPLACING AN OVERSIZED AND UNDERLOADED ELECTRIC MOTOR  

E-Print Network (OSTI)

This fact sheet will assist in decisions regarding replacement of oversized and underloaded motors. It includes a discussion of how the MotorMaster software can be used to conduct motor replacement analyses. Motors rarely operate at their full-load point. Field tests of 60 motors at four industrial plants indicate that, on average, they operate at 60 % of their rated load. 1 Motors that drive supply or return air fans in heating, ventilation and air-conditioning (HVAC) systems generally operate at 70 % to 75 % of rated load. 2 A persistent myth is that oversized motors, especially motors operating below 50 % of rated load, are not efficient and should be immediately replaced with appropriately sized energy-efficient units. In actuality, several pieces of information are required to complete an accurate assessment of energy savings. They are the load on the motor, the operating efficiency of the motor at that load point, the full-load speed (in revolutions per minute [rpm]) of the motor to be replaced, and the full-load speed of the downsized replacement motor. 3 Motor Load Estimation Techniques Operating efficiency and motor load values must be assumed or based on field measurements and

Electric motors: Markets, trends, and applications  

SciTech Connect

Electric motors play an important role in nearly all sectors of the US economy. Typical motor applications range from air conditioning and appliances in the residential sector, to cooling and space heating in the commercial sector, to materials handling and processing in the industrial sectors. Motors in the residential sector consumed nearly 352 billion kilowatthours (BkWh) in 1985, in the commercial sector 279 BkWh, and the industrial sector 552 BkWh. Approximately 87% of electric motor electricity use in the industrial sector was consumed in manufacturing processes, while the process industries consumed more than half of the manufacturing sector's electric motor electricity use. The total motor population in all sectors in 1987 stood just shy of 1.02 billion, 90% of which are less than one horsepower (HP) in size. An increasing percentage of the motor population is comprised of high efficiency motors, as classified by the National Electrical Manufacturers Association (NEMA). High efficiency motors offer end-users greater energy and cost savings than do their standard efficiency counterparts. This report provides an overview of the history of the electric motor, a brief description of the electromechanical theory behind motor operations, and offers a statistical review of the size and distribution of the electric motor market. The report also presents data on sector motor electricity use, describes current and potential motor application opportunities, and details areas in which further research and development may be needed.

Three phase AC motor controller  

DOE Patents (OSTI)

A motor controller for a three phase AC motor (10) which is adapted to operate bidirectionally from signals received either from a computer (30) or a manual control (32). The controller is comprised of digital logic circuit means which implement a forward and reverse command signal channel (27, 29) for the application of power through the forward and reverse power switching relays (16, 18, 20, 22). The digital logic elements are cross coupled to prevent activation of both channels simultaneously and each includes a plugging circuit (65, 67) for stopping the motor upon the removal of control signal applied to one of the two channels (27, 29) for a direction of rotation desired. Each plugging circuit (65, 67) includes a one-shot pulse signal generator (88, 102) which outputs a single pulse signal of predetermined pulsewidth which is adapted to inhibit further operation of the application of power in the channel which is being activated and to apply a reversal command signal to the other channel which provides a reversed phase application of power to the motor for a period defined by the pulse-width output of the one-shot signal generator to plug the motor (10) which will then be inoperative until another rotational command signal is applied to either of the two channels.

Skyrmions from Instantons inside Domain Walls  

SciTech Connect

Some years ago, Atiyah and Manton described a method to construct approximate Skyrmion solutions from Yang-Mills instantons. Here we present a dynamical realization of this construction using domain walls in a five-dimensional gauge theory. The non-Abelian gauge symmetry is broken in each vacuum but restored in the core of the domain wall, allowing instantons to nestle inside the wall. We show that the world volume dynamics of the wall is given by the Skyrme model, including the four-derivative term, and the instantons appear as domain wall Skyrmions.

Chemistry in Motion: Tiny Synthetic Motors  

E-Print Network (OSTI)

In this Account, we describe how synthetic motors that operate by self-diffusiophoresis make use of a self-generated concentration gradient to drive motor motion. A description of propulsion by self-diffusiophoresis is presented for Janus particle motors comprising catalytic and noncatalytic faces. The properties of the dynamics of chemically powered motors are illustrated by presenting the results of particle-based simulations of sphere-dimer motors constructed from linked catalytic and noncatalytic spheres. The geometries of both Janus and sphere-dimer motors with asymmetric catalytic activity support the formation of concentration gradients around the motors. Because directed motion can occur only when the system is not in equilibrium, the nature of the environment and the role it plays in motor dynamics are described. Rotational Brownian motion also acts to limit directed motion, and it has especially strong effects for very small motors. We address the following question: how small can motors be and still exhibit effects due to propulsion, even if only to enhance diffusion? Synthetic motors have the potential to transform the manner in which chemical dynamical processes are carried out for a wide range of applications.

Domain Walls and Vortices in Chiral Symmetry Breaking  

E-Print Network (OSTI)

We study domain walls and vortices in chiral symmetry breaking in a QCD-like theory with N flavors in the chiral limit. If the axial anomaly is absent, there exist stable Abelian axial vortices winding around the spontaneously broken U(1)_A symmetry and non-Abelian axial vortices winding around both the U(1)_A and non-Abelian SU(N) chiral symmetries. In the presence of the axial anomaly term, metastable domain walls are present and Abelian axial vortices must be attached by N domain walls, forming domain wall junctions. We show that a domain wall junction decays into N non-Abelian vortices attached by domain walls, implying its metastability. We also show that domain walls decay through the quantum tunneling by creating a hole bounded by a closed non-Abelian vortex.

Dynamics of Domain Wall Networks  

E-Print Network (OSTI)

Networks or webs of domain walls are admitted in Abelian or non-Abelian gauge theory coupled to fundamental Higgs fields with complex masses. We examine the dynamics of the domain wall loops by using the moduli approximation and find a phase rotation induces a repulsive force which can be understood as a Noether charge of Q-solitons. Non-Abelian gauge theory allows different types of loops which can be deformed to each other by changing a modulus. This admits the moduli geometry like a sandglass made by gluing the tips of the two cigar-(cone-)like metrics of a single triangle loop. We conclude that the sizes of all loops tend to grow for a late time in general models with complex Higgs masses, while the sizes are stabilized at some values once triplet masses are introduced for the Higgs fields. We also show that the stationary motion on the moduli space of the domain wall webs represents 1/4 BPS Q-webs of walls.

Extend the Operating Life of Your Motor  

Energy.gov (U.S. Department of Energy (DOE))

Certain components of motors degrade with time and operating stress. Electrical insulation weakens over time with exposure to voltage unbalance, over and undervoltage, voltage disturbances, and temperature. Contact between moving surfaces causes wear. Wear is affected by dirt, moisture, and corrosive fumes and is greatly accelerated when lubricant is misapplied, becomes overheated or contaminated, or is not replaced at regular intervals. When any components are degraded beyond the point of economical repair or replacement, the motors economic life ends.

Artificial neural network based torque calculation of switched reluctance motor without locking the rotor  

Science Journals Connector (OSTI)

Feedback of motor torque is required in most of switched reluctance (SR) motor applications in order to control torque and its ripple. An SR motor shows highly nonlinear property which does not allow calculating torque analytically. Torque can be directly measured by torque sensor but it inevitably increases the cost and has to be properly mounted on the motor shaft. Instead of torque sensor finite element analysis(FEA) may be employed for torque calculation. However motor modeling and calculation takes relatively long time. The results of FEA may also differ from the actual results. The most convenient way seems to calculate torque from the measured values of rotor position current and flux linkage while locking the rotor at definite positions. However this method needs an extra assembly to lock the rotor. In this study a novel torque calculation based on artificial neural networks (ANNs) is presented. Magnetizing data are collected while a 6/4 SR motor is running. They need to be interpolated for torque calculation. ANN is very strong tool for data interpolation. ANN based torque estimation is verified on the 6/4 SR motor and is compared by FEA based torque estimation to show its validity.

Radial-Gap Permanent Magnet Motor and Drive Research FY 2004  

SciTech Connect

The objective of this task was to study permanent magnet (PM) radial-gap traction drive systems that could meet the U.S. Department of Energy FreedomCAR Program's 2010 goals to expose weaknesses or identify strengths. Initially, the approach was to compare attributes such as physical deformations during operation, performance (torque, power, efficiency versus speed), material requirements (strength), material costs, manufacturability, weight, power density, specific power, reliability, and drivability for specific motors. Three motors selected were the commercially available 60-kW radial-gap surface-mounted PM motor manufactured by UQM Technologies, Inc.; a hypothetical PM motor with rotor-supported magnets similar to the Honda MCF-21; and Delphi's automotive electric machine drive motor, whose rotor is a ferromagnetic cylinder, held at one end by a shaft that supports the magnets on its inner surface. Potential problems have appeared related to PM motors, such as (1) high no-load spin losses and high operational power losses, probably from eddy current losses in the rotor; (2) the undemonstrated dual mode inverter control (DMIC) for driving a brushless dc motor (BDCM) (UQM and Delphi motors); (3) uncertainty about the potential for reducing current with DMIC; and (4) uncertainty about the relation between material requirements and maximum rotor speed. Therefore, the approach was changed to study in detail three of the comparison attributes: drivability, performance, and material requirements. Drivability and related problems were examined by demonstrating that DMIC may be used to drive an 18-pole 30-kW PM motor to 6000 rpm, where the maximum electrical frequency is 900 Hz. An available axial-gap test motor with 18 poles was used because its control is identical to that of a radial gap PM motor. Performance was analytically examined, which led to a derivation showing that DMIC controls a PM motor so that the motor uses minimum current to produce any power regardless of speed for relative speeds, n = {omega}/{omega}{sub base} {ge} 2. Performance was also examined with efficiency measurements during the 30-kW PM motor test. Material requirements were examined with finite-element analyses (FEA) to determine the speed and location where yield starts and the corresponding deformations and stresses.

Dynamic behavior analysis of a switched reluctance motor  

Science Journals Connector (OSTI)

Within the home appliances sector the series motor practically shares most applications. However no further progress in cost reduction or control performances is envisaged. But the switched reluctance motor SRM shows fairly good characteristics such as robustness easy assembly and low manufacturing costs. Besides it allows accomplishment of integrated designs with the product and an improvement of efficiency up to 90% when compared to about 45% reached by series motors used for home appliances. However two specific drawbacks of this machine are control complexity and acoustic noise. As a first step with respect to the acoustic noise the target of this work is to develop a theoretical modal model of an SRM of four phases with 24 poles in an external stator and 18 poles rotor placed inside. This requires a theoretical simulation by means of an FEM software and an experimental work in a test bench to analyze the motor structure. The comparison of the results obtained by both methods will validate the theoretical modelanalyzed with the FEM software and introduce structural modifications that can be used to design quiet SRMs from the knowledge of mode shapes and mode frequencies.

Nanoconfined catalytic ngstrm-size motors  

E-Print Network (OSTI)

Chemically-powered synthetic micron and nano-scale motors that propel themselves in solution are being intensively studied because of the wide range of potential applications that exploit their directed motion. Recent experiments have shown that, even on the molecular scale, small-molecule catalysts and single enzyme molecules exhibit properties that have been attributed to self-propulsion. Simulations of very small {\\AA}ngstr\\"om-size synthetic motors in bulk solution have shown similar effects. Applications of such small motors in the cell or in microfluidic devices require knowledge of how these motors interact with boundaries. Molecular dynamics is used to investigate the properties of {\\AA}ngstr\\"om-size synthetic chemically-powered motors confined between walls separated by distances of tens of nanometers. Evidence for strong structural ordering of the motors between the walls, which reflects the finite size of solvent molecules and depends on solvent exclusion forces, is provided. Dynamical properties, such as average motor velocity, orientational relaxation and mean square displacement, are anisotropic and depend on the distance from the walls. This research presents information needed for potential applications that use these motors in the complex confined geometries encountered in biology and the laboratory.

Design of a high power density, permanent magnet, axial gap dc motor  

SciTech Connect

In the design of drive motors for undersea vehicles, the premium placed on noise suppression suggests the use of a brush-commutated dc motor. The additional constraints of weight and volume, as well as unusual configuration, presents the axial air-gap configuration, with a permanent magnet field, as a viable candidate. In such a configuration the design of the brushes and commutator and the resulting structure becomes critical. The report describes a novel solution to this problem. The basic motor consists of two discs containing permanent magnets on either side of a magnetic structure containing the copper windings. An advantage of this motor concept is that copper cooling may easily be accomplished through the use of liquid circulating through the stator windings. The role of field and armature in a conventional disc motor configuration are reversed. The two discs containing the permanent magnets are rotating. The brushes are on the discs. The magnetic structure with the coils is stationary. The commutator bars are imbedded in the stationary member. Input power is supplied to the brushes through a brush-and-slip ring assembly. An electromagnetic design analysis for a 92 ft-lb, 700 rpm motor was performed. A finite element analysis has been conducted and the results show that magnetic saturation is not a limiting factor in this design. The motor torque is achievable within weight and volume constraints. 9 figs., 1 tab.

Coupling between Switching Regulation and Torque Generation in Bacterial Flagellar Motor  

Science Journals Connector (OSTI)

The bacterial flagellar motor plays a crucial role in both bacterial locomotion and chemotaxis. Recent experiments reveal that the switching dynamics of the motor depend on the rotation speed of the motor, and thus the motor torque, nonmonotonically. Here we present a unified mathematical model which treats motor torque generation based on experimental torque-speed curves and the torque-dependent switching based on the conformational spread model. The model successfully reproduces the observed switching rate as a function of the rotation speed, and provides a generic physical explanation independent of most details. A stator affects the switching dynamics through two mechanisms: accelerating the conformational flipping rate of individual rotor-switching units, which contributes most when the stator works at a high torque and thus a low speed; and influencing a larger number of rotor-switching units within unit time, whose contribution is the greatest when the motor rotates at a high speed. Consequently, the switching rate shows a maximum at intermediate speed, where the above two mechanisms find an optimal output. The load-switching relation may serve as a mechanism for sensing the physical environment, similar to the chemotaxis mechanism for sensing the chemical environment. It may also coordinate the switch dynamics of motors within the same cell.

A Five-Leg Inverter for Driving a Traction Motor and a Compressor Motor  

SciTech Connect

This paper presents an integrated inverter for speed control of a traction motor and a compressor motor to reduce the compressor drive cost in EV/HEV applications. The inverter comprises five phase-legs; three of which are for control of a three-phase traction motor and the remaining two for a two-phase compressor motor with three terminals. The common terminal of the two-phase motor is tied to the neutral point of the three-phase traction motor to eliminate the requirement of a third phase leg. Further cost savings are made possible by sharing the switching devices, dc bus filter capacitors, gate drive power supplies, and control circuit. Simulation and experimental results are included to verify that speed control of the two motors is independent from each other.

Skyrmions from Instantons inside Domain Walls  

E-Print Network (OSTI)

Some years ago, Atiyah and Manton described a method to construct approximate Skyrmion solutions from Yang-Mills instantons. Here we present a dynamical realization of this construction using domain walls in a five-dimensional gauge theory. The non-abelian gauge symmetry is broken in each vacuum but restored in the core of the domain wall, allowing instantons to nestle inside the wall. We show that the worldvolume dynamics of the wall is given by the Skyrme model, including the four-derivative term, and the instantons appear as Skyrmions.

A new energy optimizing control strategy for switched reluctance motors  

SciTech Connect

This paper describes a new and machine-independent method to minimize the energy consumption of a speed controlled Switched Reluctance Motor (SRM). The control strategy is to vary the duty cycle of the applied dc voltage in order to obtain the desired speed quickly and when operating in steady-state vary the turn-on angle ({alpha}{sub on}) of the phase voltage to minimize the energy consumption. The power flow is measured in the dc-link and used to control the turn-on angle. Simulations carried out on a three-phase 6/4 pole SRM justify the algorithm and the physical implementation in a Siemens SAB 80C517A microcontroller is described. Measurements on two different load systems show it is possible to minimize the energy consumption on-line in a speed controlled Switched Reluctance Motor without losing the dynamic performance. A comparison with an ordinary mode-shift controlled SRM shows more than an 8% increase in overall efficiency for some operation points. The algorithm is fully applicable to other Switched Reluctance Motors at other power levels or with other pole configurations.

Motor control and torque coordination of an electric vehicle actuated by two in-wheel motors  

Science Journals Connector (OSTI)

In this research, an electric vehicle actuated by two in-wheel DC motors is developed. By properly coordinating the motor torques, both drive-by-wire and electrical steering can be achieved. Two critical issues respectively related to the design of motor controllers and the coordination of the two motor torques under control saturation are investigated in this study. Firstly, as for the in-wheel motors that are used for driving and steering simultaneously, their operation covers a wider dynamic range that forward acceleration (deceleration), and reverse acceleration (deceleration) may occur alternately. To perform driving and steering smoothly and efficiently, each motor should be switched to an appropriate mode to generate the torque demanded. Secondly, during the high-speed maneuvering, the high back-emf voltage in the motor coil substantially reduces the motors torque generating capability. Since the electrical steering depends on the differential torque of two wheels, when electrical steering is demanded in this case, torque/current saturation may occur in either one of the motors and the electrical steering performance could be seriously degraded. To address these issues, controllers of two levels are proposed. For the low-level controller (the motor controller), it operates the motor automatically in an appropriate mode for performance and efficiency consideration. An input transformation is introduced to cancel the nonlinearity in current dynamics so as to control the motor torque easily and precisely regardless of mode switching. For the high-level controller (the torque coordination controller), besides generating reference commands to the low-level controllers, during control saturation it can also properly re-distributes control signals to maintain consistent steering performance and provides compensation for integrator windup. The control system is implemented and the performance is experimentally and numerically validated.

Hybrid stator-pole switched reluctance motor to improve radial force for bearingless application  

Science Journals Connector (OSTI)

A novel hybrid stator-pole switched reluctance motor (HSPSRM) to improve radial force for bearingless application is presented in this paper. The proposed motor can generate a constant suspending force independent of rotor position only using small current excitation. And torque control can be naturally decoupled form suspending force control. Measured data and the results of numerical analysis are given to evaluate the motor structure. In the numerical analysis, the finite element method (FEM) is employed due to the highly nonlinear nature of the motor. A prototype hybrid stator-pole SRM is manufactured and tested in the experimental studies. The obtained test and simulation results show that the hybrid stator-pole SRM structure has a constant suspending force, which can be controlled independent from torque control.

Dynamic vibration analysis of a swash-plate type water hydraulic motor  

Science Journals Connector (OSTI)

This paper presents the study of the dynamic analysis of a swash-plate water hydraulic motor in a modern water hydraulic system. A swash-plate mechanism is modeled as a system with three masses and 14 degrees of freedom (DOF). In order to evaluate the applicability of the dynamic model, the numerical simulation analysis of the dynamic response of the model due to pressure pulsation is presented and compared with experimental results. A series of the dynamic vibration characteristics of the water hydraulic piston motor are studied by the numerical simulation. It is effective for the model to simulate the vibration signal of the casing in the hydraulic motor. The waveform and frequency of the simulated signal is similar to the experimental signal. The simulated signals in other directions show that the vibration signals in all the directions mainly consist of the hydraulic pump and hydraulic motor rotational frequencies.

Thermodynamics of free Domain Wall fermions  

E-Print Network (OSTI)

Studying various thermodynamic quantities for the free domain wall fermions for both finite and infinite fifth dimensional extent N_5, we find that the lattice corrections are minimum for $N_T\\geq10$ for both energy density and susceptibility, for its irrelevant parameter M in the range 1.45-1.50. The correction terms are, however, quite large for small lattice sizes of $N_T\\leq8$. We propose modifications of the domain wall operator, as well as the overlap operator, to reduce the finite cut-off effects to within 10% of the continuum results of the thermodynamic quantities for the currently used N_T=6-8 lattices. Incorporating chemical potential, we show that \\mu^2 divergences are absent for a large class of such domain wall fermion actions although the chiral symmetry is broken for $\\mu\

Synchronous motor with soft start element formed between the motor rotor and motor output shaft to successfully synchronize loads that have high inertia and/or high torque  

DOE Patents (OSTI)

A line-start synchronous motor has a housing, a rotor shaft, and an output shaft. A soft-start coupling portion is operatively coupled to the output shaft and the rotor shaft. The soft-start coupling portion is configurable to enable the synchronous motor to obtain synchronous operation and to drive, at least near synchronous speed during normal steady state operation of the motor, a load having characteristics sufficient to prevent obtaining normal synchronous operation of the motor when the motor is operatively connected to the load in the absence of the soft-start coupling. The synchronous motor is sufficiently rated to obtain synchronous operation and to drive, at least near synchronous speed during normal steady state operation of the motor, a load having characteristics sufficient to prevent obtaining normal synchronous operation of the motor when the motor is operatively connected to the load in the absence of the soft-start coupling.

Report on Toyota Prius Motor Thermal Management  

SciTech Connect

In the current hybrid vehicle market, the Toyota Prius drive system is considered the leader in electrical, mechanical, and manufacturing innovations. It is a significant accomplishment that Toyota is able to manufacture and sell the vehicle for a profit. The Toyota Prius traction motor design approach for reducing manufacturing costs and the motor s torque capability have been studied and tested. The findings were presented in two previous Oak Ridge National Laboratory (ORNL) reports. The conclusions from this report reveal, through temperature rise tests, that the 2004 Toyota Prius (THSII) motor is applicable only for use in a hybrid automobile. It would be significantly undersized if used in a fuel cell vehicle application. The power rating of the Prius motor is limited by the permissible temperature rise of the motor winding (170 C) and the motor cooling oil (158 C). The continuous ratings at base speed (1200 rpm) with different coolant temperatures are projected from test data at 900 rpm. They are approximately 15 kW with 105 C coolant and 21 kW with 35 C coolant. These continuous ratings are much lower than the 30 kW specified as a technical motor target of the U.S. Department of Energy FreedomCAR Program. All tests were conducted at about 24 C ambient temperature. The load angle of each torque adjustment was monitored to prevent a sudden stop of the motor if the peak torque were exceeded, as indicated by the load angle in the region greater than 90 electrical degrees. For peak power with 400 Nm torque at 1200 rpm, the permissible running time depends upon the initial winding temperature condition. The projected rate of winding temperature rise is approximately 2.1 C/sec. The cooling-oil temperature does not change much during short peak power operation. For light and medium load situations, the efficiency varies from 80% to above 90%, and the power factor varies from 70% to above 90%, depending on the load and speed. When the motor is loaded heavily near the peak-torque (400-Nm) region, the efficiency goes down to the 40-50% range, and the power factor is nearly 100%. The efficiency is not a major concern at the high-torque region. The water-ethylene-glycol heat exchanger attached to the motor is small. During continuous operation, it dissipates about 76% of the total motor heat loss with 35 C coolant. The heat exchanger is less effective when the coolant temperature increases. With 75 C coolant, the heat exchanger dissipates about 38% of the motor heat. When the coolant temperature is 105 C, the heat exchanger not only stops cooling the motor but also adds heat to the large motor housing that acts as an air-cooled heat sink. From start to the base speed, 400 Nms of torque can be produced by the Prius motor with a reasonably low stator current. However, the permissible running time of the motor depends on the load drawn from the motor and the coolant temperature. In the Toyota Prius hybrid configuration, if the motor gets too hot and cannot keep running, the load can be shifted back to the engine. The motor acts to improve the system efficiency without being overly designed. A detailed thermal model was developed to help predict the temperature levels in key motor components. The model was calibrated and compared with the experimentally measured temperatures. Very good agreement was obtained between model and experiment. This model can now be used to predict the temperature of key motor components at a variety of operating conditions and to evaluate the thermal characteristics of new motor designs. It should be pointed out that a fuel-cell motor does not have an engine to fall back on to provide the needed wheel power. Therefore, the design philosophy of a fuel-cell motor is very different from that of a hybrid Prius motor. Further thermal management studies in the high-speed region of the Prius motor, fed by its inverter, are planned.

Products of motor burnout. Final report  

SciTech Connect

The Montreal Protocol of 1987 effectively banned a long list of chlorofluorocarbons (CFCs) traditionally used in air conditioning and refrigeration applications. The refrigeration and air conditioning industries have responded by developing and testing new, alternative refrigerants that are less damaging to the atmosphere upon release. Despite a reputation for quality and reliability, air conditioning systems do occasionally fail. One of the more common failure modes in a hermetic system is a motor burnout. Motor burnouts can occur by various mechanisms. One of the most common scenarios is a locked motor rotor, which may result from a damaged bearing. The resulting electrical motor burnout is caused by overheating of the locked rotor and subsequent failure of the insulation. This is primarily a thermal breakdown process.

Improving the efficiency of electric motor systems: Moving beyond efficient motors  

SciTech Connect

Electric motors operating in the US consume more than half of the nation's electricity. Electric utilities were among the first groups to begin offering programs to promote efficiency in electric motors. A 1994 Electric Power Research Institute (EPRI) survey of utility demand-side management (DSM) programs found 151 efficient-motors and drives programs being offered by 95 utilities in the US. The most common programs have been prescriptive rebates for the purchase of high-efficiency motors. While many of these programs have been popular and successful, their cost is an issue of contention with some industrial consumer groups and within utilities attempting to reduce program costs. With the minimum motor efficiency regulations in the Energy Policy Act of 1992 (EPAct) set to go into effect for most products in October 1997, utilities will need to move beyond these simple high-efficiency motor rebate programs if they are to continue to offer motor programs to their customers. The focus will also have to shift from simply motors to motor-system issues. As a 1993 US Department of Energy (DOE)-sponsored motor-system roundtable identified, motor-system expertise is not widely available, and many electric utilities will need assistance to develop and implement new programs. It is thus important that information be made available to these utilities on how to analyze customers' motor-systems needs, what program designs will most likely meet these needs, what resources they will need to implement their programs, and where to find those resources. DOE's Motor Challenge has already been identifying or developing many of these resources, and these are already being used by some utilities. If utilities are provided a program context, more of them can make better use of these resources and achieve success from their own standpoint (e.g., increased customer satisfaction and improved customer retention), from the customers' standpoint (e.g., lower motor-system costs and improved performance), and from the national standpoint (e.g., reduced motorsystem energy consumption and lower carbon emissions). The American Council for an Energy-Efficient Economy (ACEEE) has begun to establish this context by analyzing utility motor-systems programs. This work builds upon past ACEEE analyses of other utility DSM programs and ACEEE's extensive involvement in the technical aspects and design of programs involving electric motor systems.

Equivalent Circuit Modeling of Hysteresis Motors  

SciTech Connect

We performed a literature review and found that many equivalent circuit models of hysteresis motors in use today are incorrect. The model by Miyairi and Kataoka (1965) is the correct one. We extended the model by transforming it to quadrature coordinates, amenable to circuit or digital simulation. 'Hunting' is an oscillatory phenomenon often observed in hysteresis motors. While several works have attempted to model the phenomenon with some partial success, we present a new complete model that predicts hunting from first principles.

Electric Field Driven Torque in Biological Rotary Motors  

E-Print Network (OSTI)

Ion driven rotary motors, such as Fo-ATP synthase (Fo) and the bacterial flagellar motor, act much like a battery-powered electric motor. They convert energy from ions as they move from high to low potential across a membrane into torque and rotary motion. Here we propose a mechanism whereby electric fields, emanating from channels in one or more stators, act on asymmetric charge distributions due to protonated and deprotonated sites in the rotor and drive it to rotate. The model predicts an ideal scaling law between torque and ion motive force, which can be hindered by mitochondrial mutations. The rotor of Fo drives the gamma-subunit to rotate within the ATP-producing complex (F1), working against an opposing torque that rises and falls periodically with angular position. Drawing an analogy with Brownian motion of a particle in a tilted washboard potential, we compute the highly nonlinear ATP production rate vs. proton motive force (pmf), showing a minimum pmf needed to drive ATP production with important me...

Halbach array DC motor/generator  

DOE Patents (OSTI)

A new configuration of DC motor/generator is based on a Halbach array of permanent magnets. This motor does not use ferrous materials so that the only losses are winding losses and losses due to bearings and windage. An "inside-out" design is used as compared to a conventional motor/generator design. The rotating portion, i.e., the rotor, is on the outside of the machine. The stationary portion, i.e., the stator, is formed by the inside of the machine. The rotor contains an array of permanent magnets that provide a uniform field. The windings of the motor are placed in or on the stator. The stator windings are then "switched" or "commutated" to provide a DC motor/generator much the same as in a conventional DC motor. The commutation can be performed by mechanical means using brushes or by electronic means using switching circuits. The invention is useful in electric vehicles and adjustable speed DC drives.

Aggregation method for motor drive systems  

Science Journals Connector (OSTI)

Abstract When many variable frequency drives are connected to a common switchboard, their aggregated effect on system dynamics can be significant. In this paper, the aggregation method for variable frequency drives and their motors in industrial facilities is proposed, which is suitable for power systems dynamic studies. The proposed method can be applied to various types of motor drive systems. There are two steps involved for the proposed aggregation method: (1) aggregate motor drive systems connected to the same bus, and (2) further combine the aggregated model of motor drive systems from Step 1 with upstream series impedance and/or transformers. Due to involvement of high-order transfer functions in dynamic models of individual motor drive systems, Pade approximation is used as a useful tool in the aggregation process. Using the proposed aggregation method, an equivalent aggregated dynamic model of motor drive systems can be obtained at the substation bus. A case study is conducted in the paper, and the proposed aggregation method is verified to be effective by the case study.

Performance analysis of PV pumping systems using switched reluctance motor drives  

SciTech Connect

A PV pumping system using switched reluctance motor (SRM) is thoroughly investigated in this work. This motor is supplied by a d.c. voltage through a simple switching circuit. This drive circuit is much simpler than the normal d.c./a.c. inverter required to supply the induction motor. The efficiency of this motor is considerably higher than that of the equivalent d.c. or induction motors. In addition, because of the simple construction, SRM is cheaper than these conventional drives. Because of the above advantages of the SRM, the proposed system has higher efficiency and lower cost as compared with other systems. A design example is studied in detail to explore the advantages of PV pumping systems based on this new drive. The study of the performance of the proposed system showed that the operating efficiency of the motor is about 85% during most of its working time. The matching efficiency between the PV array and the proposed system approaches 95%. The major part of the losses takes place in the pump and the riser pipes. This loss represents one-third of the total available energy. 21 refs., 10 figs.

Research on a novel Rotor Structure Switched Reluctance Motor  

Science Journals Connector (OSTI)

The paper proposes a novel switched reluctance motor with improved rotor structure, in which the segment core is embedded in aluminum rotor block in order to increase the mechanical strength and easy manufacturing as well as to improve the performance characteristics and reduce the vibration and acoustic noise. The effect of design parameters on the average torque is investigated using the finite element method. Comparison with conventional VR type SRM and segment type SRM without conductive metal construction rotor show the proposed novel SRM has advantages in the torque performances and the vibration and noise characteristics. The performance is also investigated by experiment.

Domain lines as fractional strings

At small nonvanishing ? this field gets a sine-Gordon potential. As a result, only two discrete degenerate BPS domain walls survive. We find an explicit solitonic solution for domain linesstringlike objects living on the surface of the domain wall which separate wallI from wall II. The domain line is seen as a BPS kink in the world-volume effective theory. We expect that the wall with the domain line on it saturates both the {1,0} and the {12,12} central charges of the bulk theory. The domain line carries a magnetic flux which is exactly 12 of the flux carried by the flux tube living in the bulk on each side of the wall. Thus, the domain lines on the wall confine charges living on the wall, resembling Polyakovs three-dimensional confinement.

Thus, the domain lines on the wall confine charges living on the wall, resembling Polyakov's three-dimensional confinement.

When Should Inverter-Duty Motors Be Specified?  

Energy.gov (U.S. Department of Energy (DOE))

Electronic adjustable speed drives, known as variable frequency drives (VFD), used to be marketed as usable with any standard motor. However, premature failures of motor insulation systems began to occur as fast-switching, pulse-width-modulated (PWM) VFDs were introduced. The switching rates of modern power semiconductors can lead to voltage overshoots. These voltage spikes can rapidly damage a motors insulation system, resulting in premature motor failure. This tip sheet discusses the effects of VFDs on induction motors and offers suggested actions.

Minimum Efficiency Standards for Electric Motors Minimum Efficiency Standards for Electric Motors Minimum Efficiency Standards for Electric Motors October 7, 2013 - 11:28am Addthis Section 313 of the Energy Independence and Security Act (EISA) of 2007 raised Federal minimum efficiency standards for general-purpose, single-speed, polyphase induction motors of 1 to 500 horsepower (hp). This new standard took effect in December 2010. The new minimum efficiency levels match FEMP's performance requirement for these motors. As a result of this increase in mandatory minimum standards and combined with the lack of significant availability of motors exceeding these standards, FEMP is suspending the purchasing specification for electric motors. Federal buyers may select for purchase any motor that meets design requirements.

Actions to promote energy-efficient electric motor repair  

Science Journals Connector (OSTI)

Electric motors are repaired 2-3 times over their lifetime. Poor repair practices, particularly widespread in developing countries, can lead to a significant increase in motor losses. It is estimated that worldwide poor repair leads to annual electricity losses of approximately 40 TWh, representing 20 Mtons of CO2 emissions. The main objective of this paper is to provide a technical basis for designing demand side management actions, which address the motor repair market. This paper brings into focus motor repair process trends, energy-efficient motors, typical repair process, actions to promote energy-efficient motor repair, energy-efficient motor rebate schemes to replace old, badly damaged motors and the factors influencing payback. This paper will be useful to energy policy makers, and Demand Side Management (DSM) staff in energy agencies and electric utilities.

Counter-Rotating Tandem Motor Drilling System  

SciTech Connect

Gas Technology Institute (GTI), in partnership with Dennis Tool Company (DTC), has worked to develop an advanced drill bit system to be used with microhole drilling assemblies. One of the main objectives of this project was to utilize new and existing coiled tubing and slimhole drilling technologies to develop Microhole Technology (MHT) so as to make significant reductions in the cost of E&P down to 5000 feet in wellbores as small as 3.5 inches in diameter. This new technology was developed to work toward the DOE's goal of enabling domestic shallow oil and gas wells to be drilled inexpensively compared to wells drilled utilizing conventional drilling practices. Overall drilling costs can be lowered by drilling a well as quickly as possible. For this reason, a high drilling rate of penetration is always desired. In general, high drilling rates of penetration (ROP) can be achieved by increasing the weight on bit and increasing the rotary speed of the bit. As the weight on bit is increased, the cutting inserts penetrate deeper into the rock, resulting in a deeper depth of cut. As the depth of cut increases, the amount of torque required to turn the bit also increases. The Counter-Rotating Tandem Motor Drilling System (CRTMDS) was planned to achieve high rate of penetration (ROP) resulting in the reduction of the drilling cost. The system includes two counter-rotating cutter systems to reduce or eliminate the reactive torque the drillpipe or coiled tubing must resist. This would allow the application of maximum weight-on-bit and rotational velocities that a coiled tubing drilling unit is capable of delivering. Several variations of the CRTDMS were designed, manufactured and tested. The original tests failed leading to design modifications. Two versions of the modified system were tested and showed that the concept is both positive and practical; however, the tests showed that for the system to be robust and durable, borehole diameter should be substantially larger than that of slim holes. As a result, the research team decided to complete the project, document the tested designs and seek further support for the concept outside of the DOE.

An analysis of induction motor testing techniques  

SciTech Connect

There are two main failure mechanisms in induction motors: bearing related and stator related. The Electric Power Research Institute (EPRI) conducted a study which was completed in 1985, and found that near 37% of all failures were attributed to stator problems. Another data source for motor failures is the Nuclear Plant Reliability Data System (NPRDS). This database reveals that approximately 55% of all motors were identified as being degraded before failure occurred. Of these, approximately 35% were due to electrical faults. These are the faults which this paper will attempt to identify through testing techniques. This paper is a discussion of the current techniques used to predict incipient failure of induction motors. In the past, the main tests were those to assess the integrity of the ground insulation. However, most insulation failures are believed to involve turn or strand insulation, which makes traditional tests alone inadequate for condition assessment. Furthermore, these tests have several limitations which need consideration when interpreting the results. This paper will concentrate on predictive maintenance techniques which detect electrical problems. It will present appropriate methods and tests, and discuss the strengths and weaknesses of each.

Speeding up a single-molecule DNA motor with a simple catalyst  

E-Print Network (OSTI)

We demonstrate a catalytic control method for speeding up the single-molecule DNA motor introduced by Li and Tan [Nano Lett. {\\bf 2}, 315 (2002)]. A key rate-limiting barrier in the reaction part of the cycle is the tendency for the second fuel strand $B$ to fold into the chair-like configuration of the original motor strand $M$. This seriously impedes the restoration reaction. We have designed a catalytic strand to inhibit the folding of $B$. Introduction of the catalyst speeds up the restoration reaction by roughly a factor of 2. The catalyst shows robust behavior for more than one cycle. The experimental data can be understood with a model with intermediate products. This technique provides dynamic control of the restoration rate of the motor without affecting the straightening rate.

Rotor reference frame models of a multiloop 2-phase motor drive in brushless DC and microstepping modes  

SciTech Connect

This paper describes non-linear models of a 2-phase permanent magnet synchronous motor drive in brushless DC and microstepping modes. The models account for everything from the main power bus up to and including the mechanical load and velocity feedback loop. In particular, the models include the power electronics for each phase complete with their internal feedback loops. Classical state space averaged power electronics models are transformed to the rotor reference frame along with the usual electromechanical variables. Since SPICE linearizes the rotor reference frame model about shaft velocity, instead of shaft angle, frequency domain methods apply. The frequency domain analysis detects unstable interactions between torque angle and deliberate feedback within the drives. Time domain simulations using stator reference frame models confirm the results. All models are SPICE-compatible but were developed on Cadence`s Analog Workbench.

Traffic of cytoskeletal motors with disordered attachment rates  

E-Print Network (OSTI)

Motivated by experimental results on the interplay between molecular motors and tau proteins, we extend lattice-based models of intracellular transport to include a second species of particle which locally influences the motor-filament attachment rate. We consider various exactly solvable limits of a stochastic multi-particle model before focusing on the low-motor-density regime. Here, an approximate treatment based on the random walk behaviour of single motors gives good quantitative agreement with simulation results for the tau-dependence of the motor current. Finally, we discuss the possible physiological implications of our results.

Domain walls riding the wave.  

SciTech Connect

Recent years have witnessed a rapid proliferation of electronic gadgets around the world. These devices are used for both communication and entertainment, and it is a fact that they account for a growing portion of household energy consumption and overall world consumption of electricity. Increasing the energy efficiency of these devices could have a far greater and immediate impact than a gradual switch to renewable energy sources. The advances in the area of spintronics are therefore very important, as gadgets are mostly comprised of memory and logic elements. Recent developments in controlled manipulation of magnetic domains in ferromagnet nanostructures have opened opportunities for novel device architectures. This new class of memories and logic gates could soon power millions of consumer electronic devices. The attractiveness of using domain-wall motion in electronics is due to its inherent reliability (no mechanical moving parts), scalability (3D scalable architectures such as in racetrack memory), and nonvolatility (retains information in the absence of power). The remaining obstacles in widespread use of 'racetrack-type' elements are the speed and the energy dissipation during the manipulation of domain walls. In their recent contribution to Physical Review Letters, Oleg Tretiakov, Yang Liu, and Artem Abanov from Texas A&M University in College Station, provide a theoretical description of domain-wall motion in nanoscale ferromagnets due to the spin-polarized currents. They find exact conditions for time-dependent resonant domain-wall movement, which could speed up the motion of domain walls while minimizing Ohmic losses. Movement of domain walls in ferromagnetic nanowires can be achieved by application of external magnetic fields or by passing a spin-polarized current through the nanowire itself. On the other hand, the readout of the domain state is done by measuring the resistance of the wire. Therefore, passing current through the ferromagnetic wire is the preferred method, as it combines manipulation and readout of the domain-wall state. The electrons that take part in the process of readout and manipulation of the domain-wall structure in the nanowire do so through the so-called spin transfer torque: When spin-polarized electrons in the ferromagnet nanowire pass through the domain wall they experience a nonuniform magnetization, and they try to align their spins with the local magnetic moments. The force that the electrons experience has a reaction force counterpart that 'pushes' the local magnetic moments, resulting in movement of the domain wall in the direction of the electron flow through the spin-transfer torque. The forces between the electrons and the local magnetic moments in the ferromagnet also create additional electrical resistance for the electrons passing through the domain wall. By measuring resistance across a segment of the nanowire, one determines if a domain wall is present; i.e., one can read the stored information. The interaction of the spin-polarized electrons with the domain wall in the ferromagnetic nanowire is not very efficient. Even for materials achieving high polarization of the free electrons, it is very difficult to move the magnetic domain wall. Several factors contribute to this problem, with imperfections of the ferromagnetic nanowire that cause domain-wall pinning being the dominant one. Permalloy nanowires, one of the best candidates for domain-wall-based memory and logic devices, require current densities of the order of 10{sup 8} A/cm{sup 2} in order to move a domain wall from a pinning well. Considering that this current has to pass through a relatively long wire, it is not very difficult to imagine that most of the energy will go to Joule heating. The efficiency of the process - the ratio of the energy converted to domain-wall motion to the total energy consumed - is comparable to that of an incandescent light bulb converting electricity to light. A step towards more efficient domain-wall-based memory devices is the advance of using alternating currents or curren

Demand, Supply, and Price Outlook for Reformulated Motor Gasoline 1995  

Gasoline and Diesel Fuel Update (EIA)

Demand, Supply, and Price Outlook for Reformulated Demand, Supply, and Price Outlook for Reformulated Motor Gasoline 1995 by Tancred Lidderdale* Provisions of the Clean Air Act Amendments of 1990 designed to reduce ground-level ozone will increase the demand for reformulated motor gaso- line in a number of U.S. metropolitan areas. Refor- mulated motor gasoline is expected to constitute about one-third of total motor gasoline demand in 1995, and refiners will have to change plant opera- tions and modify equipment in order to meet the higher demand. The costs incurred are expected to create a wholesale price premium for reformu- lated motor gasoline of up to 4.0 cents per gallon over the price of conventional motor gasoline. This article discusses the effects of the new regulations on the motor gasoline market and the refining

Development of a Switched Reluctance Motor made of Permendur  

Science Journals Connector (OSTI)

A switched reluctance (SR) motor consists of stator and rotor cores, and windings. Both the stator and rotor have salient poles. The stator has concentrated windings on each salient pole. On the other hand, the rotor has no windings and no permanent magnets. Therefore, the SR motor is a low cost, extremely robust, and wide-range variable-speed motor. The performance of the SR motor greatly depends on magnetic properties of core material since it consists of only iron cores and windings. This paper presents the development of a novel SR motor made of permendur which has extremely high saturation flux density and very low core loss. Two types of SR motors, one is made of conventional non-oriented Si steel, the other is made of permendur, are compared by simulation and experiment. It is demonstrated that the torque of the SR motor made of permendur is greater than that of the conventional Si steel by 20%.

SciTech Connect

REACT Project: QM Power will develop a new type of electric motor with the potential to efficiently power future generations of EVs without the use of rare-earth-based magnets. Many of todays EV motors use rare earth magnets to efficiently provide torque to the wheels. QM Powers motors would contain magnets that use no rare earth minerals, are light and compact, and can deliver more power with greater efficiency and at reduced cost. Key innovations in this project include a new motor design with iron-based magnetic materials, a new motor control technique, and advanced manufacturing techniques that substantially reduce the cost of the motor. The ultimate goal of this project is to create a cost-effective EV motor that offers the rough peak equivalent of 270 horsepower.

Domain Walls, Triples and Acceleration  

E-Print Network (OSTI)

We present a construction of domain walls in string theory. The domain walls can bridge both Minkowski and AdS string vacua. A key ingredient in the construction are novel classical Yang-Mills configurations, including instantons, which interpolate between toroidal Yang-Mills vacua. Our construction provides a concrete framework for the study of inflating metrics in string theory. In some cases, the accelerating space-time comes with a holographic description. The general form of the holographic dual is a field theory with parameters that vary over space-time.

Motor regulation results in distal forces that bend partially disintegrated Chlamydomonas axonemes into circular arcs  

E-Print Network (OSTI)

The bending of cilia and flagella is driven by forces generated by dynein motor proteins. These forces slide adjacent microtubule doublets within the axoneme, the motile cytoskeletal structure. To create regular, oscilla- tory beating patterns, the activities of the axonemal dyneins must be coordinated both spatially and temporally. It is thought that coordination is mediated by stresses or strains, which build up within the moving axoneme, and somehow regulate dynein activity. While experimenting with axonemes subjected to mild proteolysis, we observed pairs of doublets associate with each other and form bends with almost constant curvature. By model- ing the statics of a pair of filaments, we show that the activity of the motors concentrates at the distal tips of the doublets. Furthermore, we show that this distribution of motor activity accords with models in which curvature, or curvature-induced normal forces, regulates the activity of the motors. These observations, together with our theoretical analysis, provide evidence that dynein activity can be regulated by curvature or normal forces, which may, therefore, play a role in coordinating the beating of cilia and flagella.

Modular PM Motor Drives for Automotive Traction Applications  

SciTech Connect

This paper presents modular permanent magnet (PM) motor drives for automotive traction applications. A partially modularized drive system consisting of a single PM motor and multiple inverters is described. The motor has multiple three-phase stator winding sets and each winding set is driven with a separate three-phase inverter module. A truly modularized inverter and motor configuration based on an axial-gap PM motor is then introduced, in which identical PM motor modules are mounted on a common shaft and each motor module is powered by a separate inverter module. The advantages of the modular approach for both inverter and motor include: (1) power rating scalability--one design meets different power requirements by simply stacking an adequate number of modules, thus avoiding redesigning and reducing the development cost, (2) increased fault tolerance, and (3) easy repairing. A prototype was constructed by using two inverters and an axial-gap PM motor with two sets of three-phase stat or windings, and it is used to assist the diesel engine in a hybrid electric vehicle converted from a Chevrolet Suburban. The effect of different pulse-width-modulation strategies for both motoring and regenerative modes on current control is analyzed. Torque and regenerative control algorithms are implemented with a digital signal processor. Analytical and initial testing results are included in the paper.

Transport of organelles by elastically coupled motor proteins  

E-Print Network (OSTI)

Motor-driven intracellular transport is a complex phenomenon where multiple motor proteins attached to a cargo are simultaneously engaged in pulling activity, often leading to tug-of-war and bidirectional motion. However, most mathematical and computational models ignore the details of the motor-cargo interaction. A few papers have studied more realistic models of cargo transport by including elastic motor-cargo coupling, but either restricts the number of motors and/or uses purely phenomenological forms for energy-dependent hopping rates. Here, we study a generic Model In which N motors are elastically coupled to a cargo, which itself is subject to thermal noise in the cytoplasm and an additional external applied force. The motor-hopping rates are chosen to satisfy detailed balance with respect to the energy of stretching. The master equation is converted to a linear Fokker-Planck equation (LFPE), which yields the average positions of the cargo and motors, as well as their fluctuations and correlation functions. We apply this formalism to two specific forms of the hopping rates. Analytical results are obtained for mean cargo velocity, diffusion coefficient and the average force experienced by each motor for arbitrary N, and compared with numerical simulations. The expansion procedure also allows us to quantify load-sharing features among the cargo-bound motors. In general, we observe significant deviations between analytical predictions based on LFPE and the corresponding numerical results, which suggests a prominent role for higher order corrections.

Motor torque compensation of an induction electric motor by adjusting a slip command during periods of supposed change in motor temperature  

DOE Patents (OSTI)

The present invention maintains constant torque in an inverter driven AC induction motor during variations in rotor temperature. It is known that the torque output of a given AC induction motor is dependent upon rotor temperature. At rotor temperatures higher than the nominal operating condition the rotor impedance increases, reducing the rotor current and motor torque. In a similar fashion, the rotor impedance is reduced resulting in increased rotor current and motor torque when the rotor temperature is lower than the nominal operating condition. The present invention monitors the bus current from the DC supply to the inverter and adjusts the slip frequency of the inverter drive to maintain a constant motor torque. This adjustment is based upon whether predetermined conditions implying increased rotor temperature or decreased rotor temperature exist for longer that a predetermined interval of time.

In situ Measurement of Robot Motor Electrical Constants  

E-Print Network (OSTI)

Motor torque constant is an important parameter in modeling and controlling a robot axis. In practice this parameter can vary considerably from the manufacturer's specification, if available, and this makes it desirable to characterise individual motors. Traditional techniques require that the motor be removed from the robot for testing, or that an elaborate technique involving weights and pulleys be employed. This paper describes a novel method for measuring the torque constant of robot servo motors in situ and is based on the equivalence of motor torque and back EMF constants. It requires a very simple experimental procedure, utilizes existing axis position sensors, and eliminates effects due to static friction and joint cross coupling. A straightforward extension to this approach can provide a measurement of motor armature impedance. Experimental results obtained for a Puma 560 are discussed and compared with other published results. 1 Introduction A large number of existing robot m...

Ferroelectric stripe domains in PbTiO{sub 3} thin films: Depolarization field and domain randomness  

SciTech Connect

Observation of stripe domains in PbTiO{sub 3} thin films using standard x-ray diffraction analysis at room temperature is discussed. High-quality c-axis oriented thin films of varying thickness, from 6 to 210 unit cells, were grown on buffered NH{sub 4}-HF etched SrTiO{sub 3}(001) and Nb:SrTiO{sub 3}(001) substrates using off-axis radio frequency magnetron sputtering. High-resolution linear Q{sub x} scans reveal a superstructure around the specular Bragg peaks, consistent with the presence of ferroelectric stripe domains. For thin samples, the stripe width is found to be proportional to the square root of the film thickness, with random in-plane orientation of domains. For films with a thickness of more than {approx}100 unit cells, both monodomain samples and stripe domains were observed. We present evidence for the presence of a threshold depolarization field, above which there is a monotonically decreasing relationship between the domain width and the depolarization field. Furthermore, simulations show that random variations in size of the domains affect the separation of the diffuse scattering peaks from that of the specular reflection.

Extending the Constant Power Speed Range of the Brushless DC Motor through Dual Mode Inverter Control -- Part I: Theory and Simulation  

SciTech Connect

An inverter topology and control scheme has been developed that can drive low-inductance, surface-mounted permanent magnet motors over the wide constant power speed range required in electric vehicle applications. This new controller is called the dual-mode inverter control (DMIC) [1]. The DMIC can drive either the Permanent Magnet Synchronous Machine (PMSM) with sinusoidal back emf, or the brushless dc machine (BDCM) with trapezoidal emf in the motoring and regenerative braking modes. In this paper we concentrate on the BDCM under high-speed motoring conditions. Simulation results show that if all motor and inverter loss mechanisms are neglected, the constant power speed range of the DMIC is infinite. The simulation results are supported by closed form expressions for peak and rms motor current and average power derived from analytical solution to the differential equations governing the DMIC/BDCM drive for the lossless case. The analytical solution shows that the range of motor inductance that can be accommodated by the DMIC is more than an order of magnitude such that the DMIC is compatible with both low- and high-inductance BDCMs. Finally, method is given for integrating the classical hysteresis band current control, used for motor control below base speed, with the phase advance of DMIC that is applied above base speed. The power versus speed performance of the DMIC is then simulated across the entire speed range.

Science Journals Connector (OSTI)

Abstract There are two ways to manufacture components and devices, the top-down and bottom-up processes. Each process has its advantages and disadvantages. In our group, the bottom-up process was selected to build up electromagnetic devices using nanoscale materials in a series of steps. The design of a lightweight electric motor is described based on using nanoscale materials. Development of the motor is work in progress and various processes and results are described. There are several potential applications for lightweight sustainable electric motors. One billion electric motors are produced in the world each year.

In this paper a comprehensive computer-aided design (CAD) procedure of multiphase switched reluctance motor (SRM) is presented. Better approach for calculation of the outer dimensions phase inductance flux linkage and losses and also a different concept for calculating the average torque of the motor are incorporated in the CAD program. The average torque is calculated based on the most effective 15 (for 8 ? 6 SRM) of the static torque profile of the motor. A sample design of a 5 hp SRM is presented in detail and the design is validated by conducting a two-dimensional finite element analysis of the motor.

Optimization of induction motor efficiency: Volume 2, Single-phase induction motors: Final report  

SciTech Connect

The optimal design of the motor dimensions, the capacitance of the run capacitor, the winding distribution and the choice of the electrical steel are the most important sources for an improvement of the efficiency of modern single-phase induction motors for given performance and material cost constraints. The formulation of the techniques which realize this optimization is based on nonlinear programming approaches. The Method of Boundary Search Along Active Constraints is used for the optimal design of the motor dimensions of a commercially available 2 hp, 115 V single-phase induction motor. Based on the optimization results due to the above mentioned four optimization components, the relationships between efficiency, power factor, cost, active materials and the values of the capacitance of the run capacitor are studied and the limited validity of the model law is discussed. This report also explains why the Wanlass retrofit improves efficiency and details the advantages and disadvantages of such a retrofitting as compared with the operation in the standard configuration.

Tuning the stator resistance of induction motors using artificial neural network  

SciTech Connect

Tuning the stator resistance of induction motors is very important, especially when it is used to implement direct torque control (DTC) in which the stator resistance is a main parameter. In this paper, an artificial network (ANN) is used to accomplish tuning of the stator resistance of an induction motor. The parallel recursive prediction error and backpropagation training algorithms were used in training the neural network for the simulation and experimental results, respectively. The neural network used to tune the stator resistance was trained on-line, making the DTC strategy more robust and accurate. Simulation results are presented for three different neural-network configurations showing the efficiency of the tuning process. Experimental results were obtained for the one of the three neural-network configuration. Both simulation and experimental results showed that the ANN have tuned the stator resistance in the controller to track actual resistance of the machine.

We take into account that the phase of the scalar field can vary using complex U(1) symmetric field and a phenomenological potential with cubic term responsible to symmetry breaking. We show that the presence of the domain wall induces subcritical bubbles so that their formation rate near the wall is considerably larger than far of it. The allowed deviations of the phases of new bubbles are so large that they prevent the system from induced nucleation.

Evolution of domain wall networks: The Press-Ryden-Spergel algorithm  

SciTech Connect

The Press-Ryden-Spergel (PRS) algorithm is a modification to the field theory equations of motion, parametrized by two parameters ({alpha} and {beta}), implemented in numerical simulations of cosmological domain wall networks, in order to ensure a fixed comoving resolution. In this paper we explicitly demonstrate that the PRS algorithm provides the correct domain wall dynamics in (N+1)-dimensional Friedmann-Robertson-Walker universes if {alpha}+{beta}/2=N, fully validating its use in numerical studies of cosmic domain evolution. We further show that this result is valid for generic thin featureless domain walls, independently of the Lagrangian of the model.

Pinkbar is an epithelial-specific BAR domain protein that generates planar membrane structures  

SciTech Connect

Bin/amphipysin/Rvs (BAR)-domain proteins sculpt cellular membranes and have key roles in processes such as endocytosis, cell motility and morphogenesis. BAR domains are divided into three subfamilies: BAR- and F-BAR-domain proteins generate positive membrane curvature and stabilize cellular invaginations, whereas I-BAR-domain proteins induce negative curvature and stabilize protrusions. We show that a previously uncharacterized member of the I-BAR subfamily, Pinkbar, is specifically expressed in intestinal epithelial cells, where it localizes to Rab13-positive vesicles and to the plasma membrane at intercellular junctions. Notably, the BAR domain of Pinkbar does not induce membrane tubulation but promotes the formation of planar membrane sheets. Structural and mutagenesis analyses reveal that the BAR domain of Pinkbar has a relatively flat lipid-binding interface and that it assembles into sheet-like oligomers in crystals and in solution, which may explain its unique membrane-deforming activity.

Batch-processed melt-textured YBCO with improved quality for motor and bearing  

Science Journals Connector (OSTI)

Results on an established batch process preparing melt-textured YBCO of high quality and in large quantities are reported. We used a standard composition Y1.5Ba2Cu3O7?x+1wt %CeO2 without further doping to fabricate single domain YBCO monoliths in different sizes and shapes (cylindrical, quadratic) as well as rectangular multi-seeded YBCO monoliths. Up to 23kg of melt-textured YBCO blocks were grown, reproducible in one box furnace run. Top seeding by a self-made SmBCO was improved and rationalized. Optimization of an oxygen annealing treatment led to macro-crack free YBCO monoliths. Each YBCO monolith was characterized by integral levitation force and field mapping. In a single domain, a quadratic monolith with a edge length of 38mm, a maximum induction of 1.44T at 77K and a distance of 0.5mm was frozen. The reproducibility of the batch process is guaranteed. Mean maximum induction from 1.1 to 1.2T at 77K per batch was reached. A trapped magnetic field of 2.5T was achieved between two single domain monoliths in a gap of 1.5mm at 77K. Depending on the application, function elements with different sizes, designs and more or less complex geometry are constructed in several working steps by cutting, machining, bonding and passivation. Selected function elements were checked with field mapping at 77K. The results of our function elements in HTSC reluctance motors with an output power of up to 200kW using single domain material are shown. We report on a fly wheel system DYNASTORE and a system to levitate people.

Summer 2002 Motor Gasoline Outlook2.doc  

Gasoline and Diesel Fuel Update (EIA)

Summer 2002 Motor Gasoline Outlook Summary For the upcoming summer season (April to September 2002), rising average crude oil costs are expected to yield above -average seasonal gasoline price increases at the pump. However, year-over-year comparisons for pump prices are still likely to be lower this summer. Inventories are at higher levels than last year in April, so some cushion against early-season price spikes is in place and price levels are expected to range below last year's averages, assuming no unanticipated disruptions. Still, OPEC production restraint and tightening world oil markets now probably mark the end of the brief respite (since last fall) from two years of relatively high gasoline prices. * Retail gasoline prices (regular grade) are expected to average $1.46 per gallon, 5

Domain formation on oxidized graphene  

Science Journals Connector (OSTI)

Using first-principles calculations within density functional theory, we demonstrate that the adsorption of a single oxygen atom results in significant electron transfer from graphene to oxygen. This strongly disturbs the charge landscape of the C-C bonds at the proximity. Additional oxygen atoms adsorbing to graphene prefer always the C-C bonds having the highest charge density and, consequently, they have the tendency to form domain structure. While oxygen adsorption to one side of graphene ends with significant buckling, the adsorption to both sides with similar domain pattern is favored. The binding energy displays an oscillatory variation and the band gap widens with increasing oxygen coverage. While a single oxygen atom migrates over the C-C bonds on the graphene surface, a repulsive interaction prevents two oxygen adatoms from forming an oxygen molecule. Our first-principles study together with finite-temperature ab initio molecular dynamics calculations conclude that oxygen adatoms on graphene can not desorb easily without the influence of external agents.

Dissipative Hamiltonian realisation and robust H? control of induction motor considering iron losses for electric vehicles  

Science Journals Connector (OSTI)

The dissipative Hamiltonian realisation and robust H? control of induction motor considering iron losses for electric vehicle are investigated in this paper. First, the dissipative Hamiltonian of the electric vehicle drive system is obtained based on the system's mathematical model in a synchronously rotating frame. Then, a robust co-ordinated tracking controller is designed based on the dissipative Hamiltonian form. One part of the controller is designed by using the method of interconnection and damping assignment to ensure the system's stability, and another part is designed by using the Hamiltonian system's robust H? technique to attenuate external disturbances. The simulation results show that the controller proposed in the paper works very well in robust tracking of induction motor.

Electric motors are one of the most common electrical components. The design phase is the most important stage in which 'green' customised solutions can be ideated, evaluated and optimised. Different aspects have to be concurrently addressed to achieve a high quality product in a short time to market. The present paper describes an innovative approach and software platform to configure and simulate customised electric motors. A key feature of the platform is a knowledge-based system that aims to standardise the design process. The platform integrates different software tools to support the development and verification of several design aspects, such as energy efficiency, manufacturing costs and environmental impacts. It also provides a collaborative area to support collaboration along the whole supply chain. Different case studies are presented to show the effectiveness of the platform application in supporting designers in the creation of innovative products.

Efficiency improvement and torque ripple minimization of Switched Reluctance Motor using FEM and Seeker Optimization Algorithm  

Science Journals Connector (OSTI)

Abstract In this paper, performance optimization of Switched Reluctance Motor (SRM) was determined using Seeker Optimization Algorithm (SOA). The most efficient aim of the algorithm was found for maximum torque value at a minimum mass of the entire construction, following changing the geometric parameters. The optimization process was carried out using a combination of Seeker Optimization Algorithm and Finite Element Method (FEM). Fitness value was calculated by FEM analysis using COMSOL3.4, and the SOA was realized by MATLAB. The proposed method has been applied for a case study and it has been also compared with Genetic Algorithm (GA). The results show that the optimized motor using SOA had higher torque value and efficiency with lower mass and torque ripple, exhibiting the validity of this methodology for SRM design.

Sensorless speed control of switched reluctance motor using brain emotional learning based intelligent controller  

Science Journals Connector (OSTI)

In this paper, a brain emotional learning based intelligent controller (BELBIC) is developed to control the switched reluctance motor (SRM) speed. Like other intelligent controllers, BELBIC is model free and is suitable to control nonlinear systems. Motor parameter changes, operating point changes, measurement noise, open circuit fault in one phase and asymmetric phases in SRM are also simulated to show the robustness and superior performance of BELBIC. To compare the BELBIC performance with other intelligent controllers, Fuzzy Logic Controller (FLC) is developed. System responses with BELBIC and FLC are compared. Furthermore, by eliminating the position sensor, a method is introduced to estimate the rotor position. This method is based on Adaptive Neuro Fuzzy Inference System (ANFIS). The estimator inputs are four phase flux linkages. Suggested rotor position estimator is simulated in different conditions. Simulation results confirm the accurate rotor position estimation in different loads and speeds.

Modeling and Simulation of Series DC Motors in Electric Car  

Science Journals Connector (OSTI)

Abstract The objective of this paper is assessing use of series DC motor in electric car with its rotation speed controller, and evaluating its performances when different running cases of electric car with different loads. The mathematical equations model of series DC motor and electronic inverter in dynamic state with reference frame d q were considered. Computer model of these equations was implemented using MATLAB/SIMPOWER facilities obtaining a complete model for motor and controller. Series DC motor is considered and its parameters were used for simulation. The electronic controller operates based on PWM control technique. Simulation of series DC motor performances was conducted within presumptions of changing car load and different resistant torques. Changing loads was realised changing number of passengers when electric car is running on normal streets, when running on streets with slope, when car is accelerate to reach a stead speed and when car is changing speed rigidly and suddenly running on country road having some holes and small slopes. Some conclusions and remarks about performances and behaviour of series DC motor were concluded. The simulated series DC motor was tested and mounted experimentally in a small truck car in Faculty of Mechanical & Electrical Engineering at Damascus University.

Energy Efficient Electric Motors BY OSCAR BRANDSER Improvements in  

E-Print Network (OSTI)

three-phase induction motors present a strong opportunity to reduce plant operating costs. Iff iciency Gap: Motors account for as much as 90 percent of the total electrical usage in commercial and industrial applications. Even small improvements in motor efficiency result in substantial energy savings. NOVEMBER/DECEMBER 1992 E lectric motors are among the most energy efficient devices man has ever created. Today, more efficient electric motors are available than ever before. Simple economics will justify investing in energy efficient motors for most commercial and industrial applications. Energy costs are on the rise and conservation practices- such as the use of energy efficient motors-will help control future energy costs. Conservation practices can help slow down electric load growth and offset the need to add generation capacity. Conservation can help improve productivity by using resources more efficiently and will also help to keep electric costs low. This is an age of increasing costs of electricity due mainly to higher demands for a limited resource and increasingly higher capital costs of new power plants. These and other factors have encouraged many utilities to develop conservation programs and increase energy efficiency awareness among their customers. Required generation capacity will be greater than available capacity in the U.S. by the Year 2000, according to some projections, without conservation and elec-

Microtubule length dependence of motor traffic in cells  

E-Print Network (OSTI)

In living cells, motor proteins, such as kinesin and dynein can move processively along microtubule (MT), and also detach from or attach to MT stochastically. Experiments have found that, the traffic of motor might be jammed, and various theoretical models have been designed to understand this traffic jam phenomenon. But previous studies mainly focus on motor attachment/detachment rate dependent properties. Recent experiment of Leduc {\\it et al.} found that the traffic jam formation of motor protein kinesin depends also on the length of MT [Proc. Natl. Acad. Sci. U.S.A. {\\bf 109}, 6100-6105 (2012)]. In this study, the MT length dependent properties of motor traffic will be analyzed. We found that MT length has one {\\it critical value} $N_c$, traffic jam occurs only when MT length $N>N_c$. The jammed length of MT increases with total MT length, while the non-jammed MT length might not change monotonically with the total MT length. The critical value $N_c$ increases with motor detachment rate from MT, but decreases with motor attachment rate to MT.

Structures of the spectrin-ankyrin interaction binding domains  

SciTech Connect

As key components of the erythrocyte membrane skeleton, spectrin and ankyrin specifically interact to tether the spectrin cytoskeleton to the cell membrane. The structure of the spectrin binding domain of ankyrin and the ankyrin binding domain of spectrin have been solved to elucidate the structural basis for ankyrin-spectrin recognition. The structure of repeats 14 and 15 of spectrin shows that these repeats are similar to all other spectrin repeats. One feature that could account for the preference of ankyrin for these repeats is the presence of a conserved, negatively charged patch on one side of repeat 14. The structure of the ankyrin ZU5 domain shows a novel structure containing a {beta} core. The structure reveals that the canonical ZU5 consensus sequence is likely to be missing an important region that codes for a {beta} strand that forms part of the core of the domain. In addition, a positively charged region is suggestive of a binding surface for the negatively charged spectrin repeat 14. Previously reported mutants of ankyrin that map to this region lie mostly on the surface of the protein, although at least one is likely to be part of the core.

Statistical CT noise reduction with multiscale decomposition and penalized weighted least squares in the projection domain  

SciTech Connect

Purposes: The suppression of noise in x-ray computed tomography (CT) imaging is of clinical relevance for diagnostic image quality and the potential for radiation dose saving. Toward this purpose, statistical noise reduction methods in either the image or projection domain have been proposed, which employ a multiscale decomposition to enhance the performance of noise suppression while maintaining image sharpness. Recognizing the advantages of noise suppression in the projection domain, the authors propose a projection domain multiscale penalized weighted least squares (PWLS) method, in which the angular sampling rate is explicitly taken into consideration to account for the possible variation of interview sampling rate in advanced clinical or preclinical applications. Methods: The projection domain multiscale PWLS method is derived by converting an isotropic diffusion partial differential equation in the image domain into the projection domain, wherein a multiscale decomposition is carried out. With adoption of the Markov random field or soft thresholding objective function, the projection domain multiscale PWLS method deals with noise at each scale. To compensate for the degradation in image sharpness caused by the projection domain multiscale PWLS method, an edge enhancement is carried out following the noise reduction. The performance of the proposed method is experimentally evaluated and verified using the projection data simulated by computer and acquired by a CT scanner. Results: The preliminary results show that the proposed projection domain multiscale PWLS method outperforms the projection domain single-scale PWLS method and the image domain multiscale anisotropic diffusion method in noise reduction. In addition, the proposed method can preserve image sharpness very well while the occurrence of 'salt-and-pepper' noise and mosaic artifacts can be avoided. Conclusions: Since the interview sampling rate is taken into account in the projection domain multiscale decomposition, the proposed method is anticipated to be useful in advanced clinical and preclinical applications where the interview sampling rate varies.

System Cost Analysis for an Interior Permanent Magnet Motor  

SciTech Connect

The objective of this program is to provide an assessment of the cost structure for an interior permanent magnet ('IPM') motor which is designed to meet the 2010 FreedomCAR specification. The program is to evaluate the range of viable permanent magnet materials for an IPM motor, including sintered and bonded grades of rare earth magnets. The study considers the benefits of key processing steps, alternative magnet shapes and their assembly methods into the rotor (including magnetization), and any mechanical stress or temperature limits. The motor's costs are estimated for an annual production quantity of 200,000 units, and are broken out into such major components as magnetic raw materials, processing and manufacturing. But this is essentially a feasibility study of the motor's electromagnetic design, and is not intended to include mechanical or thermal studies as would be done to work up a selected design for production.
