Industrial Electric Motor Systems Market Opportunities Assessment  

E-Print Network [OSTI]

(DOE) Office of Energy Efficiency and Renewable Energy (EERE) in December 1998. As of fiscal year 2000, DOEs Motor Challenge Program was integrated into BestPractices, a broad initiative within EERE. EEREs BestPractices introduces industrial end users to emerging technologies and cost-saving opportunities in widely used industrial systems. Best-Practices offers resources, tools, and information. Thus, industrial end users can match new and verified energy-efficient technologies and practices to their individual plant needs. Since the original printing, there have been some minor changes. The inside and outside back cover (last two pages) were deleted because they contained outdated program information. In addition, some minor corrections were made to the appendices.

Electric motors: Markets, trends, and applications  

SciTech Connect (OSTI)

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.

Development of Ulta-Efficient Electric Motors  

SciTech Connect (OSTI)

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

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-

Electric motor systems in developing countries: Opportunities for efficiency improvement  

SciTech Connect (OSTI)

This report presents an overview of the current status and efficiency improvement potential of industrial motor systems in developing countries. Better management of electric motor systems is of particular relevance in developing countries, where improved efficiency can lead to increased productivity and slower growth in electricity demand. Motor systems currently consume some 65--80% of the industrial electricity in developing countries. Drawing on studies from Thailand, India, Brazil, China, Pakistan, and Costa Rica, we describe potential efficiency gains in various parts of the motor system, from the electricity delivery system through the motor to the point where useful work is performed. We report evidence of a significant electricity conservation potential. Most of the efficiency improvement methods we examine are very cost-effective from a societal viewpoint, but are generally not implemented due to various barriers that deter their adoption. Drawing on experiences in North America, we discuss a range of policies to overcome these barriers, including education, training, minimum efficiency standards, motor efficiency testing protocols, technical assistance programs, and financial incentives.

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

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

SciTech Connect (OSTI)

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.

In that time CSA has proven to not only be useful for manually applied periodic monitoring of electrically driven equipment but it has also been demonstrated to be well suited for dedicated monitoring systems in industrial settings. Recent work has resulted in the development and installation of a system that can monitor up to 640 motor and compressor stages for various aerodynamic conditions in the gas compressors and electrical problems in the drive motors. This report describes a demonstration of that technology installed on 80 stages at each of the two USEC uranium enrichment plants.

Cigre`s Electra magazine published this interview with Alfonso Limbruno, CEO of ENEL S.p.A. To put the interview in perspective, this article begins with a brief overview of ENEL and a biographical sketch of Alfonso Limbruno, and also carries comments from Y. Thomas, secretary general of CIGRE. ENEL is a vertically integrated nationwide electricity company engaged in the generation, transmission, distribution, and sale of electricity, predominantly in Italy. ENEL`s share accounts for approximately 80 percent of Italian electricity demand. Measured by amount of electricity sold, ENEL is the third largest electric utility in the OECD countries and the second largest electric utility in Europe. Measured by revenues, ENEL is one of the largest companies in Italy, with a turnover of Lit. 37,632 billion. In 1995, ENEL served approximately 28.5 million customers and sold 211,607 GWh of electricity. ENEL`s gross installed generating capacity at December 31, 1995 was 55,906 MW. Alfonso Limbruno made all his career in the Italian electricity supply industry (ESI) and has had quite a unique experience: he went through a complete cycle of change of the ESI in his country, the nationalization of the sector in 1962 with the merging in ENEL of over 1,200 undertakings, and now the privatization of the company, along with a far reaching restructuring of the industry. He was appointed CEO of ENEL in August 1992.

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.

A comparative assessment of Brazilian electric motors performance with minimum efficiency standards  

Science Journals Connector (OSTI)

Abstract The industrial electric motor is the most important load, considering its large number and associated energy consumption, being responsible for approximately 68% of the industrial energy consumption and 35% of the total electrical energy consumption in Brazil. This country, like others, is seeking to establish a regulation on the minimum efficiency index for electric motor equipment. This paper aims to present an overview of the installed park of industrial motors in Brazil and to evaluate the possible effects of such regulation. For this purpose, the measurement results obtained in the 20002012 period were used, which were extracted from the approximately 276 three-phase induction motors that had been sold and were being used in the Brazilian market, with a rated power in a large range from under 1hp to over 150hp. The analysis of the measurement results provided an overview of the average behavior of the induction motors in industry while considering energy efficiency and allowing estimates and proposals aiming at the improvement of the use of electrical energy.

This paper is focused on using solid-state welding to join rectangular wires in the fabrication of motor stators. Resistance welding has not typically been applied to copper due to its very high electrical conductivity; however through optimization of the current and pressure profiles, excellent quality copper-to-copper joints have been demonstrated with a technique known as resistance mash welding. A better understanding of resistance mash welding characteristics will help advancements in its application for stators. The limitations of this application will be discussed.

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.

Determining Electric Motor Load and Efficiency  

Broader source: Energy.gov [DOE]

To compare the operating costs of an existing standard motor with an appropriately-sized energy-efficient replacement, you need to determine operating hours, efficiency improvement values, and load. Part-load is a term used to describe the actual load served by the motor as compared to the rated full-load capability of the motor. Motor part-loads may be estimated through using input power, amperage, or speed measurements. This fact sheet briefly discusses several load estimation techniques.

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.

Efficient, High-Torque Electric Vehicle Motor: Advanced Electric Vehicle Motors with Low or No Rare Earth Content  

SciTech Connect (OSTI)

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.

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.

Studying the Performances of Induction Motor Used in Electric Car  

Science Journals Connector (OSTI)

Abstract This research includes study of the performances of induction motor used in the electric car, as well as performances of an electronic inverter based on Field Oriented control used to drive this induction motor. The running equations of IM and Controller in dynamic state with reference frame d q were considered. These equations were modelled into computer form based using Matlab Simpower facilities obtaining a complete model. 3-Phase IM is considered and its parameters were used for simulation, in order to be mounted in certain car that is manufactured in Syria, and transform it to electric car. Also, it includes a study of electronic inverter appropriate to drive such motor and control its speed. It operates based on vector control technology. The study of the motor performances was conducted within presumptions of changing car load from one passenger (the driver) to five passengers and having different resistant torques. The tests of induction motor used in the electric car simulate running of the car having one passenger when car is stopped; simulate running of electric car starting IM from 0 speed and accelerating till a steady speed is reached, keeping this steady speed for a period of time, then reduce speed till car is stopped and finely Simulate running of electric car on rural roads having some holes and small slopes which cause several small acceleration and sudden breaks. Some conclusions and remarks about performances and behaviour of IM were concluded.

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.

DOE Patents [OSTI]

A method is provided for controlling a power train system for a hybrid electric vehicle. The method includes a torque distribution strategy for controlling the engine and the electric motor. The engine and motor commands are determined based upon the accelerator position, the battery state of charge and the amount of engine and motor torque available. The amount of torque requested for the engine is restricted by a limited rate of rise in order to reduce the emissions from the engine. The limited engine torque is supplemented by motor torque in order to meet a torque request determined based upon the accelerator position.

Electric industry restructuring in Michigan  

SciTech Connect (OSTI)

This Staff Report suggests a modified approach designed to significantly increase the ability of all customer classes to participate and share in the benefits of competition. The concepts discussed in this Report are designed to ensure that rates are not increased for any customers as a result of restructuring and, where possible, rates are reduced through the use of rate reduction bonds. The program outlined in this Report is designed to fulfill five objectives. First, it protects the interests of smaller customers, including low-income residential customers and senior citizens. Second, the program provides opportunities to strengthen Michigan`s business community. Third, the program includes funding for employee retraining to assure that utility employees are not negatively impacted by restructuring. Fourth, the phase-in program provides the utilities with the opportunity to prepare for competition so that they remain Michigan-based companies. Fifth, the program is designed to foster competition upon a level playing field. The Commission has jurisdiction over all investor electric utilities and rural electric cooperatives in Michigan. Municipal electric utilities are not subject to Commission jurisdiction. Although this Report discusses details regarding Consumers Power and Detroit Edison, its concepts and principles are intended to apply to all jurisdictional electric utilities.

Electric top drives gain wide industry acceptance  

SciTech Connect (OSTI)

Since its introduction, the top drive drilling system has gained acceptance as a productive and safe method for drilling oil and gas wells. Originally, the system was used mostly for offshore and higher cost land drilling, and it had to be installed as a permanent installation because of its enormous weight and size. Essentially, a top drive replaces the kelly and rotary table as the means of rotating drillpipe on oil, gas and geothermal rigs and is considered to be 15% to 40% more efficient than a kelly drive. Top drive systems allow the operator to drill and maintain directional orientation for triple stands and provide tripping efficiency because of the ability to ream and circulate with triple stands, to reduce the risk of stuck pipe or lost wells, and to improve well control and pipe handling safety. The paper describes electric top drives with DC motors, top drives with AC motors, top drives with permanent magnet motors, and top drives with permanent magnet brushless synchronous motors.

Innovative software platform for eco-design of efficient electric motors  

Science Journals Connector (OSTI)

Electric motors are one of the most common electrical components used both in industrial and household applications. In order to reduce world energy consumption and environmental impact, electric motors need to be improved in terms of efficiency and eco-sustainability. For this reason it is necessary to improve environmental consciousness, favouring the application of eco-design guidelines in the design phase, which is the most important stage where green solutions can be rapidly ideated, evaluated and optimized. Different aspects have to be concurrently considered in order to achieve a high quality product in a short time to market. In this context, the present paper describes an innovative web-based software platform to configure and simulate customized energy efficient electric motors. The core of the platform is a knowledge-based system which aims to standardize the design process according to the rules which represent the company know-how and best practices. The platform integrates different software tools to support the development from conceptual design to detailed design, and from the configuration of design solutions up to environmental impact assessment and manufacturing cost evaluation. It also provides a collaborative area in order to improve the collaboration among remote users involved in the design process, thanks to the sharing of important design data and models. The presented practical case studies demonstrate the effectiveness of the platform application. The achieved results demonstrate the improvement of the configured solutions in comparison with the traditional adopted motors. The new motors exhibit both a considerable increase in energy efficiency and at the same time relevant improvement in product sustainability combined with acceptable production costs.

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...

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.

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.

In August 1979, Halbach submitted a paper entitled ``Design of Permanent Multipole Magnets with Oriented Rare Earth Cobalt Material.`` In this paper, he presented a novel method of generating multipole magnetic fields using non-intuitive geometrical arrangements of permanent magnets. In subsequent publications, he further defined these concepts. Of particular interest to one of the authors (RFP) was the special magnet array that generated a uniform dipole field. In 1990 Post proposed the construction of an electric machine (a motor/generator) using a dipole field based on Klaus Halbach`s array of permanent magnets. He further proposed that such a system should be employed as an integral part of ``an electromechanical battery`` (EMB), i.e., a modular flywheel system to be used as a device for storing electrical energy, as an alternative to the electrochemical storage battery. This paper reviews Halbach`s theory for the generation of a dipole field using an array of permanent magnet bars, presents a simple analysis of a family of novel ``ironless`` electric machines designed using the dipole Halbach array, and describes the results obtained when they were tested in the laboratory.

Submerged electricity generation plane with marine current-driven motors  

DOE Patents [OSTI]

An underwater apparatus for generating electric power from ocean currents and deep water tides. A submersible platform including two or more power pods, each having a rotor with fixed-pitch blades, with drivetrains housed in pressure vessels that are connected by a transverse structure providing buoyancy, which can be a wing depressor, hydrofoil, truss, or faired tube. The platform is connected to anchors on the seafloor by forward mooring lines and a vertical mooring line that restricts the depth of the device in the water column. The platform operates using passive, rather than active, depth control. The wing depressor, along with rotor drag loads, ensures the platform seeks the desired operational current velocity. The rotors are directly coupled to a hydraulic pump that drives at least one constant-speed hydraulic-motor generator set and enables hydraulic braking. A fluidic bearing decouples non-torque rotor loads to the main shaft driving the hydraulic pumps.

Fan-shape optimisation using CFD and genetic algorithms for increasing the efficiency of electric motors  

Science Journals Connector (OSTI)

The electric motor efficiency represents the effectiveness with which the motor converts electrical energy into mechanical energy. As the energy losses are converted into heat, which is dissipated by the motor frame aided by internal and external fans, a better cooling system adds up to better efficiency. In recent years, improvements in motor efficiency have been achieved but at higher costs. By using Genetic Algorithms (GAs), changes are introduced to the fan shape looking for a better aerodynamic performance. The evaluation of the achieved fan efficiency with the modified shapes is performed with Computational Fluid Dynamics (CFD) simulation software.

Design of outer-rotor-type multipolar switched reluctance motor for electric vehicle  

Science Journals Connector (OSTI)

In an electric vehicle(EV) with in-wheel motors reducing the weight of the motor is a very important problem in order to improve the driving performance. In this paper we examine the lightweight design of an outer-rotor-type multipolar switched reluctance (SR) motor applied to a prototype EV. We design three SR motors which have different yoke widths and calculate the motor characteristics at a steady rotational speed based on a finite element method. We discuss the optimum relationship between a pole and yoke widths.

Testing Performance of 10 kW BLDC Motor and LiFePO4 Battery on ITB-1 Electric Car Prototype  

Science Journals Connector (OSTI)

Abstract The growing development of Electric vehicle industry due to more greener transportation needs, encouraging ITB as a research based educational institution to give their effort and participation in developing electric city car prototype, especially for Indonesia used. Two fundamental components in the electric car are the electric motor and its energy storage system. The motor used in this ITB-1electric car is brushless dc (BLDC) motor type. A controller will be used to convert the dc source into ac for BLDC motor power source. How far an electric car can reach their destination depends on how much energy that is stored in the batteries. This electrical energy storage will affect performance of the electric car. Therefore we have to protect the battery from anything that can make the battery's life shorter. Voltage is one of the parameters that must be controlled by the battery management system, so that the battery can be protected effectively. In this paper, a10kW BLDC motor and its energy storagei.e LiFePO4 battery types, will be evaluated based on their performance result from the tests.

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...

The 4 phase VSR motor: The ideal prime mover for electric vehicles  

SciTech Connect (OSTI)

4 phase variable switched reluctance motors are gaining acceptance in many applications due to their fault tolerant characteristics. A 4 phase variable switched reluctance motor (VSR) is modelled and its performance is predicted for several operating points for an electric vehicle application. The 4 phase VSR offers fault tolerance, high performance, and an excellent torque to weight ratio. The actual system performance was measured both on a teststand and on an actual vehicle. While the system described is used in a production electric motorscooter, the technology is equally applicable for high efficiency electric cars and buses. 4 refs.

A computer-based total productive maintenance model for electric motors  

Science Journals Connector (OSTI)

The paper describes the development of a computer-based total productive maintenance (TPM) model to improve electrical motors readiness and uptime while reducing capital overhead. The TPM model includes the consideration of reactive, periodic, and predictive practices. The input data is processed and the generated report details a set of periodic recommendations providing guidelines on recommended actions and their frequency. The details about test results indicating the current condition of the motor as well estimated reactive, periodic, and predictive maintenance cost details are presented. Based on the historic data stored in its database, the model can predict potential problems prior to failure as well as prescribe periodic maintenance actions to maximise motor life. The TPM model will be a useful tool to predict the degradation in motor life due to deterioration in insulation, bearing, rotor bar and stator windings of the motor.

Potential energy savings and reduction of CO2 emissions through higher efficiency standards for polyphase electric motors in Japan  

Science Journals Connector (OSTI)

Japan has shut down more than 70% of its nuclear power plants since the March 2011 Tohoku earthquake and the ensuing accident at the Fukushima Daiichi nuclear power plant. The country has been challenged with power shortages in the short-term and faces complex energy security decisions in the long-term. Japan has a long history of implementing energy conservation policies, such as the Top Runner Program, which covers 23 products including appliances and industrial equipment. However, Japan's efficiency policy for polyphase electric motors is considered below international standards. Polyphase electric motors accounted for about 55% of the nation's total power consumption in 2008. The aim of this study is to estimate potential energy savings and reduction in CO2 emissions (20142043) by examining scenarios involving adopting two different polyphase motor efficiency standards and comparing them to a base case and concludes by suggesting pathways for further policy development using the results obtained. The study finds that if level IE2 of the international efficiency standard IEC 60034-30 were implemented, it would save 8.3TWh (or 0.03 quads) per year, which is equivalent to about 0.8% of Japan's total electric power consumption in 2010. If level IE3 of the IEC 60034-30 were implemented instead, it would save about 13.3TWh (or 0.05 quads) per year. The corresponding cumulative energy savings and reduction in CO2 emissions for the IE2 scenario would be 249TWh (or 0.85 quads) and 93Mt. The corresponding cumulative energy savings and reduction in CO2 emissions for the IE3 scenario would be 398TWh (or 1.36 quads) and 149Mt.

Novel digital control of conventional electric motor drives for home appliances  

Science Journals Connector (OSTI)

Research has been done on developing advanced control strategies for industrial DC motor drives. However, there is little advancement in the controllers designed for small appliance motors, which still use old and inefficient methods of control. The old methods of appliance motor control are the triac control and the PWM control. These methods are cheap and easy to implement, but they have a drawback not regulating the controlled quantity properly and fast enough. The only reason they still persist in the appliance market is because of their cost of implementation. Appliance markets are very sensitive to cost changes; therefore, everything for an appliance motor is optimised for low cost. In this paper, we present a new control strategy for appliance motors, which is inherently digital in nature. 'The pulse adjustment method' can be used to control the speed of appliance motors very effectively. The implementation is easy and the cost of implementation is also low; yet, this method gives better results as compared to the PWM and triac control. The said performance of the pulse adjustment method is proven through simulations.

Manufacturability and assembly aspects of an advanced cable gland design for an electrical motor drive  

Science Journals Connector (OSTI)

At present, typical motor junction boxes do not incorporate cable glands, which would provide good electrical performance in terms of electromagnetic compatibility and ease of use, especially regarding the grounding connection. In this paper, a manufacturability and assembly analysis for the new construction of a rigid body feeder cable junction of an electric motor is presented especially for converter drives. Design for manufacturing and assembly aspects are presented in detail. One of the novelty values of the paper is to estimate the manufacturability with respect to the product's performance. Further, assembling and mounting the cable gland should be made easy, and the need of various tools and installing stages should be eliminated. The new connector design makes mounting easy and installation stages are minimised. The electrical performance of the cable gland is also measured and verified in a real environment for glands constructed with steel and zinc coated steel.

An integrated approach and IT platform to optimise electric motor engineering and design  

Science Journals Connector (OSTI)

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.

Novel estimation of tyre-road friction coefficient and slip ratio using electrical parameters of traction motor for electric vehicles  

Science Journals Connector (OSTI)

The estimation of the friction coefficient and the slip ratio is crucial for advanced traction control or anti-brake control of electric vehicles. In this paper, dynamic behaviours of electrical parameters of the traction motor under road change are modelled and analysed. Novel estimation only using the measurements of the armature voltage and the current is proposed. The proposed method is much quicker than traditional methods, contributing to adjust the vehicle's motion state more quickly and precisely. Further, it can eliminate the speed measuring devices of the wheel speed and the vehicle speed. Simulations verify the effectiveness.

Fault-tolerant cruise control of electric vehicles with induction motors  

Science Journals Connector (OSTI)

A fault-tolerant control scheme is proposed for the cruise control of electric vehicles (trains, cars) that make use of induction motors. It relies on a rotor speed reference generator and on a flux observer which is adaptive with respect to the uncertain rotor and stator resistances and to the load torque as well. The closed loop on-line identification of those three critical uncertain parameters allows for: (i) on-line estimating and imposing the motor flux modulus reference value which minimizes power losses at steady-state and improves power efficiency; (ii) the on-line detection of speed sensor faults as well as the fast switching on redundant motor speed sensors. CarSim simulations illustrate the effectiveness of the proposed approach.

PM Motor Parametric Design Analyses for a Hybrid Electric Vehicle Traction Drive Application  

SciTech Connect (OSTI)

The Department of Energy's (DOE) Office of FreedomCAR (Cooperative Automotive Research) and Vehicle Technologies office has a strong interest in making rapid progress in permanent magnet (PM) machine development. The DOE FreedomCAR program is directing various technology development projects that will advance the technology and hopefully lead to a near-term request for proposals (RFP) for a to-be-determined level of initial production. This aggressive approach is possible because the technology is clearly within reach and the approach is deemed essential, based on strong market demand, escalating fuel prices, and competitive considerations. In response, this study began parallel development paths that included a literature search/review, development and utilization of multiple parametric models, verification of the modeling methodology, development of an interior PM (IPM) machine baseline design, development of alternative machine baseline designs, and cost analyses for several candidate machines. This report summarizes the results of these activities as of September 2004. This report provides background and summary information for recent machine parametric studies and testing programs that demonstrate both the potential capabilities and technical limitations of brushless PM machines (axial gap and radial gap), the IPM machine, the surface-mount PM machines (interior or exterior rotor), induction machines, and switched-reluctance machines. The FreedomCAR program, while acknowledging the progress made by Oak Ridge National Laboratory (ORNL), Delphi, Delco-Remy International, and others in these programs, has redirected efforts toward a ''short path'' to a marketable and competitive PM motor for hybrid electric vehicle (HEV) traction applications. The program has developed a set of performance targets for the type of traction machine desired. The short-path approach entails a comprehensive design effort focusing on the IPM machine and meeting the performance targets. The selection of the IPM machine reflects industry's confidence in this market-proven design that exhibits a high power density.

Phase 1 STTR flywheel motor/alternator for hybrid electric vehicles. CRADA final report  

SciTech Connect (OSTI)

Visual Computing Systems (VCS) and the Oak Ridge National Laboratory (ORNL) have teamed, through a Phase 1 Small Business Technology Transfer (STTR) grant from the US Department of Energy (DOE), to develop an advanced, low-cost motor/alternator drive system suitable for Flywheel Energy Storage (FES) applications. During Phase 1, system performance and design requirements were established, design concepts were generated, and preliminary motor/alternator designs were developed and analyzed. ORNL provided mechanical design and finite element collaboration and Lynx Motion Technology, a spin-off from VCS to commercialize their technology, constructed a proof-of-concept axial-gap permanent magnet motor/alternator that employed their Segmented Electromagnetic Array (SEMA) with a survivable design speed potential of 10,000 rpm. The VCS motor/alternator was successfully tested in ORNL`s Motor Test Tank using an ORNL inverter and ORNL control electronics. It was first operated as an unloaded motor to 6,000 rpm and driven as an unloaded generator to 6,000 rpm. Output from the generator was then connected to a resistance bank, which caused the loaded generator to decelerate to 3,860 rpm where data was collected. After about 4-1/2 minutes, the test was terminated because of an impact noise. Subsequent inspection and operation at low speeds did not reveal the source of the noise. Electrical performance of the motor was excellent, encouraging continued development of this technology. Phase 2 efforts will focus on further design development and optimization, manufacturing development and prototype construction, testing, and evaluation.

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.

Output feedback control for robust tracking of position trajectories for DC electric motors  

Science Journals Connector (OSTI)

Abstract A generalized PI-like output feedback dynamic control scheme with additional integral compensation of the output error is proposed for robust tracking tasks of position reference trajectories for direct current electric motors with speed reduction gear head, using measurements of angular displacement only. The integral compensation is used to improve the robustness property of the controller, in regards to parametric uncertainty and variable load torque, and avoid the application of asymptotic estimation methods of the state vector. A family of Taylor polynomials approximates the perturbation signals, in order to reduce the control design complexity. These signals are compensated by the integral control action directly. Experimental and simulation results describe the effective performance of the control scheme proposed in this paper as an alternative solution to the efficient angular position control problem of direct current electric motors.

Electricity distribution industry restructuring, electrification, and competition in South Africa  

SciTech Connect (OSTI)

This paper reviews the status of the South African electricity supply industry (ESI) and proposals for reorienting and restructuring it. South Africa has been intensely examining its ESI for more than 4 years in an effort to determine whether and how it should be restructured to best support the country`s new economic development and social upliftment goals. The debate has been spirited and inclusive of most ESI stakeholders. The demands on and expectations for the ESI are many and varied. The debate has reflected this diversity of interests and views. In essence, however, there is a consensus on what is expected of the industry, namely, to extend provision of adequate, reliable, and affordable electricity service to all citizens and segments of the economy. This means a large-scale electrification program to reach as many of the nearly 50% of households currently without electricity service as soon as possible, tariff reform to promote equity and efficiency, and the upgrading of service quality now being provided by some of the newly consolidated municipal authorities. The issues involved are how best to achieve these results within the context of the national Reconstruction and Development Program, while accounting for time and resource constraints and balancing the interests of the various parties.

Bias reduction for reliable fault detection of electric motors under measurement noise of non-zero means  

Science Journals Connector (OSTI)

Model identification and fault detection are of importance for reliable motor control. For fault diagnosis, motor parameters must be estimated accurately and reliably during operation. Typical measurement noises for power electronics encounter unknown and drifting non-zero means. This causes identification bias and has detrimental effects on reliability of fault detection. Based on enhanced model structures of electric motors that accommodate both normal and faulty modes, this paper introduces algorithms that correct this bias and restore diagnosis accuracy. BLDC motors are used as a benchmark type for concrete algorithm development and evaluation. Algorithms are presented, their properties are established, and their accuracy and robustness are evaluated by case studies.

Modelling and simulation of the electronic differential system for an electric vehicle with two-motor-wheel drive  

Science Journals Connector (OSTI)

In-wheel-motor drive electric vehicle (EV) is an innovative configuration, in which each wheel is driven individually by an electric motor. It is possible to use an electronic differential (ED) instead of the heavy mechanical differential because of the fast response time of the motor. A new control approach for ED of a two in-wheel-motor drive EV is proposed based on the fuzzy logic control. The fuzzy logic method employs to estimate the slip rate of each wheel considering the complex and non-linear of the system. Consequently, the ED system distributes torque and power to each motor according to requirements. The effectiveness of the control method is validated in the Matlab/Simulink environment. By simulation results, it is demonstrated that the present ED control system is effective on keeping the slip rate within the optimal range and ensuring the stability of the vehicle either on a straight or curvilinear line.

The prevalent motor bearing premature failures due to the high frequency electric current passage  

Science Journals Connector (OSTI)

Abstract Bearing premature failures are prevalent in VFD (Variable Frequency Drives) motors. The three common symptoms of the modern bearing current appeared on the bearings of a group of pump motors. The bearing failure mechanisms have been studied from the tribological point of view. The natures of the three common symptoms have been uncovered. A hypothesis of the skin effect has been proposed to explain the three common symptoms. The discovery of the serial microcraters reveals the discharge with Fourier series features. The nature of the fluting patterns excluded the theories of both EDM (Electrical Discharge Machining) and discharge corrugation. VA (Vibration Analysis) detected the harmonics of the BPOR (Ball Pass Outer Ring) frequency which associated with the fluting on the outer raceway. This discovery may be applied to detect fluting in condition monitoring.

Control methods of the switched reluctance motor in electric vehicle during acceleration  

Science Journals Connector (OSTI)

In this paper the equations describing the performance of the electric vehicle are derived. Performance characteristics for each part in the vehicle system are obtained when the vehicle is accelerated under voltage turn on and turn off angle control. A comparison between the different methods of control is established. From these comparisons it can be noticed that the acceleration time for the case at which the turn on angle is controlled will be smaller than that for the other cases; also the motor efficiency at the voltage control method has the highest value especially at the higher values of the vehicle speed.

Analysis on cogging torque of driving in-wheel motor for electric vehicle  

Science Journals Connector (OSTI)

In order to reduce the torque fluctuation, vibration and acoustic noise of driving in-wheel motor for electric vehicle, this paper researches the generation mechanism and influence factors of cogging torque. Based on energy method and Fourier expansion, an analytical method is proposed to establish the expression of cogging torque, which can express its relation with design parameters. Based on the expression, the match of pole and slot, pole arc coefficient and permanent magnet eccentric distance are analysed and studied. Ansoft software is used to establish a time-varying movement electromagnetic field finite element model, which can compute the cogging torque about the different match of the pole and slot, different pole arc coefficient and different permanent magnet eccentric distance, in order to obtain the change regularity of the corresponding cogging torque. The conformity of the final simulation computation results with the theoretical analysis indicates this method can be used to provide a theoretical basis to make further optimal design of the new driving in-wheel motor and its control system, so as to reduce torque ripple of in-wheel motor.

Transition-cost issues for a restructuring US electricity industry  

SciTech Connect (OSTI)

Utilities regulators can use a variety of approaches to calculate transition costs. We categorized these approaches along three dimensions. The first dimension is the use of administrative vs. market procedures to value the assets in question. Administrative approaches use analytical techniques to estimate transition costs. Market valuation relies on the purchase price of particular assets to determine their market values. The second dimension concerns when the valuation is done, either before or after the restructuring of the electricity industry. The third dimension concerns the level of detail involved in the valuation, what is often called top-down vs. bottom-up valuation. This paper discusses estimation approaches, criteria to assess estimation methods, specific approaches to estimating transition costs, factors that affect transition-cost estimates, strategies to address transition costs, who should pay transition costs, and the integration of cost recovery with competitive markets.

Wavelet based Neuro-Detector for low frequencies of vibration signals in electric motors  

Science Journals Connector (OSTI)

This study presents a Wavelet based Neuro-Detector approach employed to detect the aging indications of an electric motor. Analysis of the aging indications, which can be seen in the low frequency region, is performed using vibration signals. More specifically, two vibration signals are observed for healthy and faulty (aged) cases which are measured from the same electric motor. Multi Resolution Wavelet Analysis (MRWA) is applied in order to obtain low and high frequency bands of the vibration signals. Thus for detecting the aging properties in the spectra, the Power Spectral Density (PSD) of the subband for the healthy case is used to train an Auto Associative Neural Network (AANN). The PSD amplitudes, which are computed for the faulty case, are applied to input nodes of the trained network for the re-calling process of AANN. Consequently, the simulation results show that some spectral properties defined in low frequency region are determined through the error response of AANN. Hence, some specific frequencies of the bearing damage related to the aging process are detected and identified.

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.

Analytical and simulation studies have been complemented with research on switching mechanisms to accomplish the task. The simulation studies conducted examine the power and energy demands on a vehicle following a series of standard driving cycles and the impact on the efficiency and battery size of an electrically propelled vehicle when it uses an IPM motor with turn-switching capabilities. Both full driving cycle electric propulsion and propulsion limited starting from zero to a set speed have been investigated.

Motor cortex activation by H-coil and figure-8 coil at different depths. Combined motor threshold and electric field distribution study  

Science Journals Connector (OSTI)

AbstractObjective To compare the ability of an H-coil and figure-8 coil to stimulate different motor cortex regions. Methods The resting (rMT) and active (aMT) motor thresholds were measured for the right hand APB and leg AHB muscles in 10 subjects, using an H-coil and a figure-8 coil. The electric field distribution induced by the coils was measured in a head model. The combination of the hand and leg \\{MTs\\} with the field measurements was used to determine the depth of hand and leg motor areas via the intersection points. Results The rMT and aMT of both APB and AHB were significantly lower for the H-coil. The ratio and difference between the leg and hand rMT and aMT were significantly lower for the H-Coil. Electric field measurements revealed significantly more favorable depth profile and larger volume of stimulation for the H-coil. The averaged intersection for the APB was at a distance from coil of 1.830.54cm and at an intensity of 97.821.4V/m, while for the AHB it was at a distance of 2.730.44cm and at an intensity of 118.621.3V/m. Conclusion The results suggest a more efficient activation of deeper motor cortical regions using the H-coil. Significance The combined evaluation of \\{MTs\\} by H- and figure-8 coils allows measurement of the individual depth of different motor cortex regions. This could be helpful for optimizing stimulation parameters for TMS treatment.

Nonsinusoidal electrical measurement accuracy in adjustable-speed motors and drives  

SciTech Connect (OSTI)

Accurate measurements of voltage, current, and power under nonsinusoidal conditions are essential for determining the efficiency of a drive system and performing separation of losses between an adjustable-speed drive (ASD) and an electric motor. That information is invaluable for equipment designers, manufacturers, and users. Three modern power meters and analyzers were tested to determine their accuracy with various nonsinusoidal waveforms applied. The meters were subjected to waveforms that are characteristic to the three most common fractional and integral horsepower ASD technologies, namely, pulsewidth modulation induction, brushless dc, and switched-reluctance drives. The tests were performed under field conditions and in a computer-controlled laboratory environment. The obtained results show that some meters are able to measure accurately electric power at the input to ASD`s. However, the output power of ASD`s for brushless dc and switched-reluctance technology was not measured with acceptable accuracy by any of the tested meters. Possible reasons of meters inaccuracies and suggestions for performance improvement are presented. Conclusions on the present state of ASD electric power measurements and recommendations for further research are given.

Vibration-based approach to lifetime prediction of electric motors for reuse  

Science Journals Connector (OSTI)

This paper is concerned with lifetime prediction of components in washing machines. Vibration signals were measured on electric motors during an accelerated lifetime test ranging from 26.7 to 38.5 simulated years. Loose bearings have initiated air-gap eccentricity and rotor-to-stator rubbing, which resulted in a motor breakdown. Significant frequency bands were identified using a spectral comparison based on the constant percentage bandwidth (CPB) spectrum. Increasing trends were extracted from several vibration indicators, such as envelope cepstrum (EC) and a weighted integral of CPB differences. The EC is computed as the real cepstrum of the envelope signal obtained by demodulating the band identified by the CPB comparison. Hence the EC is more sensitive as it employs a priori information provided by historical data. The fault was first detected 9.7 years in advance and confirmed 5.3 years before the breakdown. The indicators can be integrated with a recent methodology based on Weibull analysis and neural network modelling.

A Soft-Switching Inverter for High-Temperature Advanced Hybrid Electric Vehicle Traction Motor Drives  

SciTech Connect (OSTI)

The state-of-the-art hybrid electric vehicles (HEVs) require the inverter cooling system to have a separate loop to avoid power semiconductor junction over temperatures because the engine coolant temperature of 105?C does not allow for much temperature rise in silicon devices. The proposed work is to develop an advanced soft-switching inverter that will eliminate the device switching loss and cut down the power loss so that the inverter can operate at high-temperature conditions while operating at high switching frequencies with small current ripple in low inductance based permanent magnet motors. The proposed tasks also include high-temperature packaging and thermal modeling and simulation to ensure the packaged module can operate at the desired temperature. The developed module will be integrated with the motor and vehicle controller for dynamometer and in-vehicle testing to prove its superiority. This report will describe the detailed technical design of the soft-switching inverters and their test results. The experiments were conducted both in module level for the module conduction and switching characteristics and in inverter level for its efficiency under inductive and dynamometer load conditions. The performance will be compared with the DOE original specification.

Development of traction control for front-wheel drive in-wheel motor electric vehicles  

Science Journals Connector (OSTI)

This paper proposes a novel traction control for a front-wheel drive in-wheel motor electric vehicle. The presented vehicle has advantages on high fuel efficiency and cost effectiveness. In order to achieve specific control performance, this study employed a high speed microcontroller as the vehicle's electronic control unit. The anti-skid function based on a reliable traction control kernel is embedded in the system, which can guarantee the steering safety in a slippery and dangerous situation. This study verifies that the traction control based on maximum torque regulation cannot only constrain the slip to improve the longitudinal friction force and lateral friction force, but also provide some information on tyre-road conditions, which can ensure the performance and the effectiveness of two-dimensional motion control. The numerical simulation and demonstration video reveal its effectiveness and feasibility.

Study on controlling chaos of permanent magnet synchronous motor in electric vehicles  

Science Journals Connector (OSTI)

The objective of this study is to analyse chaotic motion and its control in a Permanent Magnet Synchronous Motor (PMSM) in an Electric Vehicle (EV). Complex non-linear behaviours are observed over a range of parameter values in the bifurcation diagram. Hopf bifurcation and chaos may even occur in the PMSMs if the PMSMs are not properly sized. The Lyapunov exponent approach is utilised to identify the onset of chaotic motion and to verify the above analyses. Finally, an approach for effectively controlling a chaotic PMSM system is presented. The state feedback control procedure is employed to control chaotic motions in the PMSM effectively. Simulation results are presented to demonstrate the feasibility of the proposed approach.

Thermal performance of oil spray cooling system for in-wheel motor in electric vehicles  

Science Journals Connector (OSTI)

Abstract The cooling of the motor in an in-wheel system is critical to its performance and durability. In the present study, the shape of the channel in the hollow shaft for the oil spray cooling of a high-capacity 35kW in-wheel motor was optimized, and the thermal performance of the motor was evaluated by numerical analysis and experiments. The thermal flow was analyzed by evaluating the thermal performance of two conventional cooling models of in-wheel motors under conditions of continuous rating base speed. For conventional model #1, in which the cooling oil is stagnant in the lower end of the motor, the maximum temperature of the coil was 221.7C. For conventional model #2, in which the cooling oil circulates through the exit and entrance of the housing and jig, the maximum temperature of the coil was 155.4C. Both models thus proved to be unsuitable for in-wheel motors because the motor control specifications limit the maximum temperature to 150C. We designed and manufactured an enhanced model for in-wheel motors, which we equipped with an optimized channel for the oil spray cooling mode, and evaluated its thermal performance under continuous rating conditions. The maximum temperatures of the coil at the base and maximum speeds, which were set as the design points, were below the motor temperature limit, being 138.1 and 137.8C, respectively.

Voluntary GHG reduction in the US electric industry  

SciTech Connect (OSTI)

The report is a study of efforts by members of the industry to voluntarily reduce their greenhouse gas emission. Dozens of US utilities are leveraging voluntary greenhouse gas (GHG) emissions reduction programs to help develop cost-effective plans for responding to future potential regulation. Many of these utilities are taking aggressive steps to reduce their GHG emissions and positioning themselves as leaders. They are participating in voluntary programs for reasons ranging from pressure by environmental groups and investors to a desire for a stronger voice in shaping climate change policy. The report takes a comprehensive look at what is driving these voluntary efforts, what government and industry help is available to support them, and what specific activities are being undertaken to reduce GHG emissions. It explains the features of the most prominent voluntary utility programs to help companies determine which might best suit their needs. 1 app.

3 Aerial view of Washington D.C. 3 Aerial view of Washington D.C. News From the D.C. Office New Work With Motor Systems The Energy Analyis Program has recently started a project for the DOE Office of Industrial Technologies Motor Challenge Program. This project, to be carried out in the Washington D.C. office, extends the office's work to an exciting new area of electric motor system efficiency. Motor systems consume about 70 percent of the electric energy used in the U.S. industrial sector. Emphasis on motor efficiency in recent years has led to passage of efficiency standards, to become effective in 1997, for most common types of motors. This is extremely important because the cost of energy consumed by a motor during its useful life typically far exceeds its acquisition cost. Frequently, significant system-level opportunities

This chapter addresses past, ongoing, and short (to 2010) and medium-term (to 2030) future actions that can be taken to mitigate GHG emissions from the manufacturing and process industries. Globally, and in most countries, CO{sub 2} accounts for more than 90% of CO{sub 2}-eq GHG emissions from the industrial sector (Price et al., 2006; US EPA, 2006b). These CO{sub 2} emissions arise from three sources: (1) the use of fossil fuels for energy, either directly by industry for heat and power generation or indirectly in the generation of purchased electricity and steam; (2) non-energy uses of fossil fuels in chemical processing and metal smelting; and (3) non-fossil fuel sources, for example cement and lime manufacture. Industrial processes also emit other GHGs, e.g.: (1) Nitrous oxide (N{sub 2}O) is emitted as a byproduct of adipic acid, nitric acid and caprolactam production; (2) HFC-23 is emitted as a byproduct of HCFC-22 production, a refrigerant, and also used in fluoroplastics manufacture; (3) Perfluorocarbons (PFCs) are emitted as byproducts of aluminium smelting and in semiconductor manufacture; (4) Sulphur hexafluoride (SF{sub 6}) is emitted in the manufacture, use and, decommissioning of gas insulated electrical switchgear, during the production of flat screen panels and semiconductors, from magnesium die casting and other industrial applications; (5) Methane (CH{sub 4}) is emitted as a byproduct of some chemical processes; and (6) CH{sub 4} and N{sub 2}O can be emitted by food industry waste streams. Many GHG emission mitigation options have been developed for the industrial sector. They fall into three categories: operating procedures, sector-wide technologies and process-specific technologies. A sampling of these options is discussed in Sections 7.2-7.4. The short- and medium-term potential for and cost of all classes of options are discussed in Section 7.5, barriers to the application of these options are addressed in Section 7.6 and the implication of industrial mitigation for sustainable development is discussed in Section 7.7. Section 7.8 discusses the sector's vulnerability to climate change and options for adaptation. A number of policies have been designed either to encourage voluntary GHG emission reductions from the industrial sector or to mandate such reductions. Section 7.9 describes these policies and the experience gained to date. Co-benefits of reducing GHG emissions from the industrial sector are discussed in Section 7.10. Development of new technology is key to the cost-effective control of industrial GHG emissions. Section 7.11 discusses research, development, deployment and diffusion in the industrial sector and Section 7.12, the long-term (post-2030) technologies for GHG emissions reduction from the industrial sector. Section 7.13 summarizes gaps in knowledge.

Cost Effective, High Efficiency Integrated Systems Approach To Auxiliary Electric Motors  

SciTech Connect (OSTI)

The CARAT program, carried out by Kinetic Art & Technology Corporation (KAT), has been one of the most commercially successful KAT R&D programs to date. Based on previous development of its technology, KAT designed, constructed and tested a highly efficient motor and controller system under this CARAT program with supplemental commercial funding. Throughout this CARAT effort, the technical objectives have been refined and refocused. Some objectives have been greatly expanded, while others have been minimized. The determining factor in all decisions to refocus the objectives was the commercial need, primarily the needs of KAT manufacturing partners. Several companies are employing the resulting CARAT motor and controller designs in prototypes for commercial products. Two of these companies have committed to providing cost share in order to facilitate the development. One of these companies is a major manufacturing company developing a revolutionary new family of products requiring the ultra-high system efficiency achievable by the KAT motor and controller technologies (known as Segmented ElectroMagnetic Array, or SEMA technology). Another company requires the high efficiency, quiet operation, and control characteristics afforded by the same basic motor and controller for an advanced air filtration product. The combined annual production requirement projected by these two companies exceeds one million units by 2005.

Weather satellites and the economic value of forecasts: evidence from the electric power industry  

Science Journals Connector (OSTI)

Data from weather satellites have become integral to the weather forecast process in the United States and abroad. Satellite data are used to derive improved forecasts for short-term routine weather, long-term climate change, and for predicting natural disasters. The resulting forecasts have saved lives, reduced weather-related economic losses, and improved the quality of life. Weather information routinely assists in managing resources more efficiently and reducing industrial operating costs. The electric energy industry in particular makes extensive use of weather information supplied by both government and commercial suppliers. Through direct purchases of weather data and information, and through participating in the increasing market for weather derivatives, this sector provides measurable indicators of the economic importance of weather information. Space weather in the form of magnetic disturbances caused by coronal mass ejections from the sun creates geomagnetically induced currents that disturb the electric power grid, sometimes causing significant economic impacts on electric power distribution. This paper examines the use of space-derived weather information on the U.S. electric power industry. It also explores issues that may impair the most optimum use of the information and reviews the longer-term opportunities for employing weather data acquired from satellites in future commercial and government activity.

Maintaining Generation Adequacy in a Restructuring U.S. Electricity Industry  

SciTech Connect (OSTI)

Historically, decisions on the amounts, locations, types, and timing of investments in new generation have been made by vertically integrated utilities with approval from state public utility commissions. As the U.S. electricity industry is restructured, these decisions are being fragmented and dispersed among a variety of organizations. As generation is deregulated and becomes increasingly competitive, decisions on whether to build new generators and to retire, maintain, or repower existing units will increasingly be made by unregulated for-profit corporations. These decisions will be based largely on investor assessments of future profitability and only secondarily on regional reliability requirements. In addition, some customers will choose to face real-time (spot) prices and will respond to the occasionally very high prices by reducing electricity use at those times. Market-determined generation levels will, relative to centrally mandated reserve margins, lead to: (1) more volatile energy prices; (2) lower electricity costs and prices; and (3) a generation mix with more baseload, and less peaking, capacity. During the transition from a vertically integrated, regulated industry to a deintegrated, competitive industry, government regulators and system operators may continue to impose minimum-installed-capacity requirements on load-serving entities. As the industry gains experience with customer responses to real-time pricing and with operation of competitive intrahour energy markets, these requirements will likely disappear. We quantitatively analyzed these issues with the Oak Ridge Competitive Electricity Dispatch model (ORCED). Model results show that the optimal reserve margin depends on various factors, including fuel prices, initial mix of generation capacity, and customer response to electricity prices (load shapes and system load factor). Because the correct reserve margin depends on these generally unpredictable factors, mandated reserve margins might be too high, leading to higher electricity costs and prices. Absent mandated reserve margins, electricity prices and costs decline with increasing customer response to prices during high-demand periods. The issues discussed here are primarily transitional rather than enduring. However, the transition from a highly regulated, vertically integrated industry to one dominated by competition is likely to take another five to ten years.

The electricity supply industry in Germany: market power or power of the market?  

Science Journals Connector (OSTI)

This paper analyses the electricity supply industry in Germany, which was liberalized in April 1998. Noticeable aspects are the eligibility of all end-users, the lack of constraints on the vertical industry structure and the option for negotiated third party access. There is no sector-specific regulation. This paper argues that the vertically integrated firms concentrate on excessive network access charges, whereas the stages generation and retail appear to be relatively competitive. Empirical evidence suggests that in Germany network access charges make up a significantly higher share of end-user prices than in the UK, which is used as regulation-benchmark.

The electric and gas industries are converging: What does it mean?  

SciTech Connect (OSTI)

Three broad views define deregulation in retail gas and electric markets. One sees the future as but a lengthened shadow of the present. Change is glacial. The second predicts a significant but mannerly shift-a leisurely transition from monopoly to competition. The third posits revolution. It awaits a future marked by epochal, discontinuous, and abrupt changes. This third future is the most interesting. It raises the stakes. This article examines the industrial organization of gas and electric enterprises as they will be reinvented by those who embrace the third view. Not a prediction; rather, a thought experiment.

ELECTRICITY CONSUMPTION IN THE INDUSTRIAL SECTOR OF JORDAN: APPLICATION OF MULTIVARIATE LINEAR REGRESSION AND ADAPTIVE NEURO?FUZZY TECHNIQUES  

Science Journals Connector (OSTI)

In this study two techniques for modeling electricity consumption of the Jordanian industrial sector are presented: (i) multivariate linear regression and (ii) neuro?fuzzy models. Electricity consumption is modeled as function of different variables such as number of establishments number of employees electricity tariff prevailing fuel prices production outputs capacity utilizations and structural effects. It was found that industrial production and capacity utilization are the most important variables that have significant effect on future electrical power demand. The results showed that both the multivariate linear regression and neuro?fuzzy models are generally comparable and can be used adequately to simulate industrial electricity consumption. However comparison that is based on the square root average squared error of data suggests that the neuro?fuzzy model performs slightly better for future prediction of electricity consumption than the multivariate linear regression model. Such results are in full agreement with similar work using different methods for other countries.

Product-service systems in the electric car industry: critical success factors in marketing  

Science Journals Connector (OSTI)

Abstract In the electric car industry the service component assumes considerable importance and it is a relevant factor in purchasing decisions. Therefore, proper management of the Product-Service System (PSS) is essential. This article aims to 1) identify the main sub-systems of the PSS in the electric car industry and 2) identify the critical success factors (CSFs) in marketing. The review of the literature led to the definition of four sub-systems: vehicle, infrastructure, on-board electronics, and energy. Based on these PSS sub-systems, organisations belonging to each sub-system were selected, and five managers were interviewed. The data were analysed using a cognitive mapping technique. Ten \\{CSFs\\} were identified, of which two belong to the vehicle sub-system (value proposition and product-service system bundle); one relates to the electronic on-board sub-system (advanced navigation systems); three relate to infrastructure sub-system (incentives, alternative transport systems and advocacy campaigns) and three belong to infrastructure and energy sub-systems (ease of use, proximity of charging point and standardisation). Finally, partnerships among players involve all the four sub-systems. Moreover, the relevance/manageability matrix offers evidence that partnerships represent a priority factor that requires immediate action from companies. The research offers a new means to identify \\{CSFs\\} by using a PSS analysis rather than taking an industry sector perspective.

Cascaded H-bridge inverter motor drives for hybrid electric vehicle applications  

Science Journals Connector (OSTI)

This paper presents the asymmetric cascaded H-bridge multilevel inverter for electric vehicles (EV) and hybrid electric vehicles (HEV) applications. Currently available power inverter systems for HEVs use a DC-DC boost converter to boost the battery voltage for a traditional three-phase inverter. The present HEV drive inverters have low power density, are expensive, and have low efficiency because they need a bulky inductor. Asymmetric cascaded H-bridge multilevel inverter design for EV and HEV applications without the use of inductors to output a boosted AC voltage is proposed in this paper. Traditionally, each H-bridge needs a DC power supply having equal values of DC power sources. The proposed design uses the asymmetric cascaded multilevel inverter using non-equal DC power sources based on specified ratios. A fundamental switching scheme is used to do modulation control and to produce a seven-level phase voltage.

Products of motor burnout. Final report  

SciTech Connect (OSTI)

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.

Remedial neural network inverse control of a multi-phase fault-tolerant permanent-magnet motor drive for electric vehicles  

Science Journals Connector (OSTI)

A five-phase in-wheel fault-tolerant interior permanent-magnet (FT-IPM) motor incorporates the merits of high efficiency, high power density and high reliability, suitable for Electric Vehicles (EVs). A new remedial Neural Networks Inverse (NNI) control strategy is proposed to attain the post-fault operation. In this scheme, the NN is used to approximate the inverse model of the FT-IPM motor. With this NNI system and the original motor drive combined, a pseudo-linear compound system can be obtained. The simulation demonstrates that the proposed control strategy leads to excellent control performance at the faulty mode and offers good robustness against load disturbance.

A Unique Approach to Power Electronics and Motor Cooling in a Hybrid Electric Vehicle Environment  

SciTech Connect (OSTI)

An innovative system for cooling the power electronics of hybrid electric vehicles is presented. This system uses a typical automotive refrigerant R-134a (1,1,1,2 tetrafluoroethane) as the cooling fluid in a system that can be used as either part of the existing vehicle passenger air conditioning system or separately and independently of the existing air conditioner. Because of the design characteristics, the cooling coefficient of performance is on the order of 40. Because liquid refrigerant is used to cool the electronics directly, high heat fluxes can result while maintaining an electronics junction temperature at an acceptable value. In addition, an inverter housing that occupies only half the volume of a conventional inverter has been designed to take advantage of this cooling system. Planned improvements should result in further volume reductions while maintaining a high power level.

An improved energy management strategy for FC/UC hybrid electric vehicles propelled by motor-wheels  

Science Journals Connector (OSTI)

Abstract The hybridization of the fuel-cell electric-vehicle (FCEV) by a second energy source has the advantage of improving the system's dynamic response and efficiency. Indeed, an ultra-capacitor (UC) system used as an energy storage device fulfills the FC slowest dynamics during fast power transitions and recovers the braking energy. In FC/UC hybrid vehicles, the search for a suitable power management approach is one of the main objectives. In this paper, an improved control strategy managing the active power distribution between the two energy sources is proposed. The UC reference power is calculated through the DC link voltage regulation. For the FC power demand, an algorithm with five operating modes is developed. This algorithm, depending on the UC state of charge (SOC) and the vehicle speed level, minimizes the FC power demand transitions and therefore ameliorates its durability. The traction power is provided using two permanent magnetic synchronous motor-wheels to free more space in the vehicle. The models of the FC/UC vehicle system parts and the control strategy are developed using MATLAB software. Simulation results show the effectiveness of the proposed energy management strategy.

Sliding mode-based DTC-SVM control of permanent magnet synchronous motors for plug-in electric and hybrid vehicles  

Science Journals Connector (OSTI)

This paper presents a sliding mode controller design for a permanent magnet synchronous motor used in an integrated powertrain for plug-in electric and hybrid vehicles. In order to adapt to complicated driving environment and improve the robustness of the system, a sliding mode-based torque controller is developed. At the same time, a sliding mode speed controller is also proposed to meet the need of gear shift of the integrated powertrain. The stability and robustness of the proposed controllers are analysed. Computer simulations are performed to verify the effectiveness of the proposed control system. The simulation results illustrate that fast response and small ripples are achieved using the proposed control scheme. It is also shown that the control system is robust against load variations, measurement errors and parameter uncertainty. In addition, the transition during shift is smooth. Therefore, the proposed control scheme is suitable for control of the propulsion motor for plug-in electric and hybrid vehicles.

Physiological observations validate finite element models for estimating subject-specific electric field distributions induced by transcranial magnetic stimulation of the human motor cortex  

Science Journals Connector (OSTI)

Abstract Recent evidence indicates subject-specific gyral folding patterns and white matter anisotropy uniquely shape electric fields generated by TMS. Current methods for predicting the brain regions influenced by TMS involve projecting the TMS coil position or center of gravity onto realistic head models derived from structural and functional imaging data. Similarly, spherical models have been used to estimate electric field distributions generated by TMS pulses delivered from a particular coil location and position. In the present paper we inspect differences between electric field computations estimated using the finite element method (FEM) and projection-based approaches described above. We then more specifically examined an approach for estimating cortical excitation volumes based on individualistic FEM simulations of electric fields. We evaluated this approach by performing neurophysiological recordings during MR-navigated motormapping experiments. We recorded motor evoked potentials (MEPs) in response to single pulse TMS using two different coil orientations (45 and 90 to midline) at 25 different locations (5נ5 grid, 1cm spacing) centered on the hotspot of the right first dorsal interosseous (FDI) muscle in left motor cortex. We observed that motor excitability maps varied within and between subjects as a function of TMS coil position and orientation. For each coil position and orientation tested, simulations of the TMS-induced electric field were computed using individualistic FEM models and compared to MEP amplitudes obtained during our motormapping experiments. We found FEM simulations of electric field strength, which take into account subject-specific gyral geometry and tissue conductivity anisotropy, significantly correlated with physiologically observed MEP amplitudes (rmax=0.91, p=1.8נ10-5 rmean=0.81, p=0.01). These observations validate the implementation of individualistic FEM models to account for variations in gyral folding patterns and tissue conductivity anisotropy, which should help improve the targeting accuracy of TMS in the mapping or modulation of human brain circuits.

Advanced Motors  

SciTech Connect (OSTI)

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.

Industrial Power Factor Analysis Guidebook.  

SciTech Connect (OSTI)

Power factor is a way of measuring the percentage of reactive power in an electrical system. Reactive power represents wasted energy--electricity that does no useful work because the electrical current is out of phase with the voltage. Reactive power is used by inductive loads (such as, motors, transformers, fluorescent lights, arc welders and induction furnaces) to sustain their magnetic fields. Electric systems with many motors exhibit low power factors, increased conductor and transformer losses, and lower voltages. Utilities must supply both active and reactive power and compensate for these losses. Power factor can be improved by the addition of shunt capacitors. Capacitors act in opposition to inductive loads, thereby minimizing the reactive power required to serve them. In raising the power factor, shunt capacitors release energy to the system, reduce system losses, and ultimately decrease power costs. Improving system power factor can reduce reactive and active power losses for both industry and utilities through the addition of shunt capacitors. This Guide Book gives electric utility technical staff, industrial end-users, consultants and BPA employees a step-by-step method for evaluating the cost effectiveness of installing power factor correction capacitors in an industrial plant.

Demand side management of industrial electricity consumption: Promoting the use of renewable energy through real-time pricing  

Science Journals Connector (OSTI)

Abstract As the installed capacity of wind generation in Ireland continues to increase towards an overall goal of 40% of electricity from renewable sources by 2020, it is inevitable that the frequency of wind curtailment occurrences will increase. Using this otherwise discarded energy by strategically increasing demand at times that would otherwise require curtailment has the potential to reduce the installed capacity of wind required to meet the national 2020 target. Considering two industrial electricity consumers, this study analyses the potential for the implementation of price based demand response by an industrial consumer to increase their proportional use of wind generated electricity by shifting their demand towards times of low prices. Results indicate that while curtailing during peak price times has little or no benefit in terms of wind energy consumption, demand shifting towards low price times is likely to increase a consumers consumption of wind generation by approximately 5.8% for every 10% saved on the consumers average unit price of electricity.

NICE3: Industrial Refrigeration System  

SciTech Connect (OSTI)

Energy Concepts has developed an absorption-augmented system as a cost-effective means of achieving more cooling capacity with a substantial reduction in energy consumption and greenhouse gas emissions for industrial refrigeration. It cuts fuel consumption by 30% by combining an internal combustion engine with a mechanical compression refrigeration system and an absorption refrigeration system. The absorption system is powered by engine waste heat. Conventional industrial refrigeration uses mechanical vapor compression, powered by electric motors, which results in higher energy costs. By the year 2010, the new system could cut fuel consumption by 19 trillion Btu and greenhouse emissions by more than 1 million tons per year.

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.

Time-of-use pricing and electricity demand response: evidence from a sample of Italian industrial customers  

Science Journals Connector (OSTI)

The introduction of real time pricing in many wholesale market as well as the liberalisation process involving the retail market poses the attention over the measurement of demand response to time differentiated price signals. This paper shows an example of how to estimate elasticities of substitution across time using a sample of Italian industrial customers facing time-of-use (TOU) pricing schemes. The model involves the estimation of a nested constant elasticity of substitution (CES) input demand function, which allows estimating substitutability of electricity usage across hourly intervals within a month and across different months.

Identification, definition and evaluation of potential impacts facing the US electric utility industry over the next decade. Final report  

SciTech Connect (OSTI)

There are numerous conditions of the generation system that may ultimately develop into system states affecting system reliability and security. Such generation system conditions should also be considered when evaluating the potential impacts on system operations. The following five issues have been identified to impact system reliability and security to the greatest extent: transmission access/retail wheeling; non-utility generators and independent power producers; integration of dispersed storage and generation into utility distribution systems; EMF and right-of-way limitations; Clean Air Act Amendments. Strictly speaking, some issues are interrelated and one issue cannot be completely dissociated from the others. However, this report addresses individual issues separately in order to determine all major aspects of bulk power system operations affected by each issue. The impacts of the five issues on power system reliability and security are summarized. This report examines the five critical issues that the US electric utility industry will be facing over the next decade. The investigation of their impacts on utility industry will be facing over the next decade. The investigation of their impacts on utility system reliability and security is limited to the system operation viewpoint. Those five issues will undoubtedly influence various planning aspects of the bulk transmission system. However, those subjects are beyond the scope of this report. While the issues will also influence the restructure and business of the utility industry politically, sociologically, environmentally, and economically, all discussion included in the report are focused only on technical ramifications.

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.

Magnetically Coupled Adjustable Speed Motor Drives  

Broader source: Energy.gov [DOE]

Alternating current electric motors rotate at a nearly constant speed that is determined by motor design and line frequency. Energy savings of 50% or more may be available when fixed speed systems are modified to allow the motor speed to match variable load requirements of a centrifugal fan or pump. This tip sheet describes the advantages of magnetically coupled ASDs and provides suggested actions.

Rare-Earth-Free Nanostructure Magnets: Rare-Earth-Free Permanent Magnets for Electric Vehicle Motors and Wind Turbine Generators: Hexagonal Symmetry Based Materials Systems Mn-Bi and M-type Hexaferrite  

SciTech Connect (OSTI)

REACT Project: The University of Alabama is developing new iron- and manganese-based composite materials for use in the electric motors of EVs and renewable power generators that will demonstrate magnetic properties superior to todays best rare-earth-based magnets. Rare earths are difficult and expensive to refine. EVs and renewable power generators typically use rare earths to make their electric motors smaller and more powerful. The University of Alabama has the potential to improve upon the performance of current state-of-the-art rare-earth-based magnets using low-cost and more abundant materials such as manganese and iron. The ultimate goal of this project is to demonstrate improved performance in a full-size prototype magnet at reduced cost.
