Parametric electric motor study  

DOE Green Energy (OSTI)

Technology for the axial gap motor was developed by DOE with an investment of approximately $15 million. This development effort is for motor technologies of high power density and high efficiency. Such motors that are also small and light-weight are not available on the commercial market because high-power motors have typically been used in large industrial applications where small size and light weight are not requirements. AC Delco has been developing motors since 1918 and is interested in leveraging its research and development dollars to produce an array of motor systems for vehicles and to develop a future line of propulsion products. The DOE focus of the study was applied to machining applications. The most attractive feature of this motor is the axial air gap, which may make possible the removal of the motor`s stationary component from a total enclosure of the remainder of the machine if the power characteristics are adequate. The objectives of this project were to evaluate alternative electric drive systems for machine tools and automotive electric drive systems and to select a best machine type for each of those applications. A major challenge of this project was to produce a small, light-weight, highly efficient motor at a cost-effective price. The project developed machine and machine drive systems and design criteria for the range of applications. The final results included the creation of a baseline for developing electric vehicle powertrain system designs, conventional vehicle engine support system designs, and advanced machine tool configurations. In addition, an axial gap permanent magnet motor was built and tested, and gave, said one engineer involved, a sterling performance. This effort will commercialize advanced motor technology and extend knowledge and design capability in the most efficient electric machine design known today.

Development of Ulta-Efficient Electric Motors  

SciTech Connect

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

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

This report covers the fifth quarter (01/01/04 to 03/31/04) of the In-Line Electric Motor Driven Compressor (IEMDC) project. Design efforts on the IEMDC continued with compressor efforts focused on performing aerodynamic analyses. These analyses were conducted using computational fluid dynamics. Compressor efforts also entailed developing mechanical designs of components through the use of solid models and working on project deliverables. Electric motor efforts focused on the design of the magnetic bearing system, motor pressure housing, and the motor-compressor interface. The mechanical evaluation of the main interface from both the perspective of the compressor manufacturer and electric motor manufacturer indicates that an acceptable design has been achieved. All mechanical and aerodynamic design efforts have resulted in considerable progress being made towards the completion of the compressor and electric motor design and towards the successful completion of the IEMDC unit.

Summary of electric vehicle dc motor-controller tests  

DOE Green Energy (OSTI)

Available performance data for production motors are usually of marginal value to the electric vehicle designer. To provide at least a partial remedy to this situation, tests of typical dc propulsion motors and controllers were conducted as part of the DOE Electric Vehicle Program. The objectives of this program were to evaluate the differences in the performance of dc motors when operating with chopper-type controllers and when operating on direct current; and to gain an understanding of the interactions between the motor and the controller which cause these differences. Toward this end, motor-controller tests performed by the NASA Lewis Research Center provided some of the first published data that quantified motor efficiency variations for both ripple-free (straight dc) and chopper modes of operation. Test and analysis work at the University of Pittsburgh explored motor-controller relationships in greater depth. And to provide additional data, 3E Vehicles tested two small motors, both on a dynamometer and in a vehicle, and the Eaton Corporation tested larger motors, using sophisticated instrumentation and digital processing techniques. All the motors tested were direct-current types. Of the separately excited types, seven were series wound and two were shunt wound. One self-excited permanent magnet type was also tested. Four of the series wound motors used brush shifting to obtain good commutation. In almost all cases, controller limitations constrained the test envelope so that the full capability of the motors could not be explored.

Aging assessment of large electric motors in nuclear power plants  

Science Conference Proceedings (OSTI)

Large electric motors serve as the prime movers to drive high capacity pumps, fans, compressors, and generators in a variety of nuclear plant systems. This study examined the stressors that cause degradation and aging in large electric motors operating in various plant locations and environments. The operating history of these machines in nuclear plant service was studied by review and analysis of failure reports in the NPRDS and LER databases. This was supplemented by a review of motor designs, and their nuclear and balance of plant applications, in order to characterize the failure mechanisms that cause degradation, aging, and failure in large electric motors. A generic failure modes and effects analysis for large squirrel cage induction motors was performed to identify the degradation and aging mechanisms affecting various components of these large motors, the failure modes that result, and their effects upon the function of the motor. The effects of large motor failures upon the systems in which they are operating, and on the plant as a whole, were analyzed from failure reports in the databases. The effectiveness of the industry`s large motor maintenance programs was assessed based upon the failure reports in the databases and reviews of plant maintenance procedures and programs.

Electric motor systems in developing countries: Opportunities for efficiency improvement  

SciTech Connect

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.

Economic Realities and Energy Efficient Polyphase Integral Horsepower Electric Motors  

E-Print Network (OSTI)

Energy efficient polyphase integral horsepower electric motors are currently being vigorously promoted as a profitable method of conserving energy in many industrial and commercial applications. While the goal to be attained is indeed laudable, and must be tenaciously pursued, the economic realities of investment payback on increased efficiency versus cost of change out, power factor, etc. must have a meaningful review before decision making. Actual savings on a discount cash flow basis must be documented. and validity of the claims for the energy efficient motor must be verified. This paper develops the procedures used by the chemical manufacturing divisions of the Union Carbide Corporation in developing a long range plan for evolution from a motor population of standard efficiency units to one of higher efficiency and increased reliability. It notes statistics publicized by the U.S. Department of Energy, Union Carbide's overall electric equipment efficiency review, their own efficiency testing of sample small electric motors, and a pilot program to determine the number of lightly loaded motors in plant location. It further depicts an economic appraisal on the payback of replacing a standard efficiency motor with a higher efficiency unit and an action plan for purchasing energy efficient motors while simultaneously securing optimization of other parameters.

Not a Babe in the Woods: Using MotorMaster Software to Make Sophisticated Electric Motor Purchase Decisions  

E-Print Network (OSTI)

Three-phase motors use more than half of all electricity in the United States. Energy efficient models are available in most motor classes in the 1 to 500 horsepower range, offering simple pay backs under two years. In practice, few motor buyers have performed an economic analysis, resulting in missed energy and dollar savings. MotorMaster software helps identify the best motor for a specific application. Its database of 9,000 motors includes the majority of three-phase motors sold in the United State. Performance information such as Full-Load RPM, torque and amperage rating identify models that meet specific design criteria. MotorMaster calculates operating costs and simple paybacks. This paper reviews the importance of proper electric motor selection and explains how MotorMaster software can be used to identify the most efficient, cost effective and reliable motor for each specific application.

Direct Lamination Cooling of Motors For Electric Vehicles  

DOE Green Energy (OSTI)

Current designs for electric motors use a housing that acts as both a structural support and as a method of cooling the stator and rotor. This approach to cooling is not as effective as possible because heat must flow from the rotor and stator through the housing to the cooling media. Because the housing must contain the coolant, it is also larger, heavier, and more expensive than necessary. This project develops a motor that uses a direct lamination cooling (DLC) system, passing coolant directly through the stator and eliminating the need for bulky housing, thereby improving heat transfer. Motor size could be reduced by up to 30-40%, mass by up to 20-30%, and cost by up to 30%. Phase I demonstrated that reliable lamination-to-lamination seals and reliable stack-to-manifold seals can be achieved using the methods identified. The addition of the selected sealants adds only slightly to the thermal resistance and pressure drop compared with unsealed counterparts. Phase II builds electric motors and inductors using the DLC method, obtain comparative performance data on the effectiveness of the method, and then obtain operational use data on these components through long term testing in a representative environment. The long-term testing will ensure that real world aspects of motor and inductor operation (including vibration, temperature cycling, and the presence of electrical and magnetic fields) do not degrade the seals such that leaking occurs or that the thermal performance degrades.

IEMDC IN-LINE ELECTRIC MOTOR DRIVEN COMPRESSOR  

SciTech Connect

This report contains the final project summary and deliverables required by the award for the development of an In-line Electric Motor Driven Compressor (IEMDC). Extensive work was undertaken during the course of the project to develop the motor and the compressor section of the IEMDC unit. Multiple design iterations were performed to design an electric motor for operation in a natural gas environment and to successfully integrate the motor with a compressor. During the project execution, many challenges were successfully overcome in order to achieve the project goals and to maintain the system design integrity. Some of the challenges included limiting the magnitude of the compressor aerodynamic loading for appropriate sizing of the magnetic bearings, achieving a compact motor rotor size to meet the rotor dynamic requirements of API standards, devising a motor cooling scheme using high pressure natural gas, minimizing the impact of cooling on system efficiency, and balancing the system thrust loads for the magnetic thrust bearing. Design methods that were used on the project included validated state-of-the-art techniques such as finite element analysis and computational fluid dynamics along with the combined expertise of both Curtiss-Wright Electro-Mechanical Corporation and Dresser-Rand Company. One of the most significant areas of work undertaken on the project was the development of the unit configuration for the system. Determining the configuration of the unit was a significant step in achieving integration of the electric motor into a totally enclosed compression system. Product review of the IEMDC unit configuration was performed during the course of the development process; this led to an alternate design configuration. The alternate configuration is a modular design with the electric motor and compressor section each being primarily contained in its own pressure containing case. This new concept resolved the previous conflict between the aerodynamic flow passage requirements and electric motor requirements for support and utilities by bounding the flowpath within the compressor section. However most importantly, the benefits delivered by the new design remained the same as those proposed by the goals of the project. In addition, this alternate configuration resulted in the achievement of a few additional advantages over the original concept such as easier maintenance, operation, and installation. Interaction and feedback solicited from target clients regarding the unit configuration supports the fact that the design addresses industry issues regarding accessibility, maintainability, preferred operating practice, and increased reliability.

Distributed monitoring system for electric-motor-driven compressors  

SciTech Connect

Personnel in the Instrumentation and Controls Division at the Oak Ridge National Laboratory, in association with the United States Enrichment corporation (USEC), the Navy, and various Department of Energy sponsors, have been involved in the development and application of motor-current signature analysis (CSA) for several years. 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.

IEMDC -IN-LINE ELECTRIC MOTOR DRIVEN COMPRESSOR  

SciTech Connect

Dresser-Rand completed the preliminary aerodynamic flowpath of the volute and inlet design for the compressor section. This has resulted in considerable progress being made on the development of the compressor section and ultimately towards the successful integration of the IEMDC System design. Significant effort was put forth in the design of aerodynamic components which resulted in a design that meets the limits of aerodynamically induced radial forces previously established. Substantial effort has begun on the mechanical design of the compressor pressure containing case and other internal components. These efforts show progression towards the successful integration of a centrifugal compressor and variable speed electric motor ventilated by the process gas. All efforts continue to confirm the feasibility of the IEMDC system design. During the third quarter reporting period, the focus was to further refine the motor design and to ensure that the IEMDC rotor system supported on magnetic bearing is in compliance with the critical speed and vibration requirements of the API standards 617 and 541. Consequently specification to design magnetic bearings was developed and an RFQ to three magnetic bearing suppliers was issued. Considerable work was also performed to complete preliminary reports on some of the deliverable tasks under phase 1.0. These include specification for the VFD, RFQ for the magnetic bearings, and preliminary write-up for motor instrumentation and control schematic. In order to estimate motor efficiency at various operating points, plots of calculated motor losses, and motor cooling gas flow rates were also prepared. Preliminary evaluations of motor support concepts were performed via FEA to determine modal frequencies. Presentation was made at DOE Morgantown on August 12, 2003 to provide project status update. Preparations for the IEMDC motor-compressor presentation, at the GMRC conference in Salt Lake City to be held on October 5, 2003, were also started. Detailed calculations of cooling gas flow requirements for the motor and magnetic bearings, per several new operating points designated by DR, confirmed that the required gas flow was within the compressor design guidelines. Previous thrust load calculations had confirmed that the magnetic thrust bearing design load capacity of 6,000 lb. was sufficient to handle the net thrust load produced by the motor and compressor pressure loading. Thus the design data that has been generated, for the variable speed 10 MW 12,000 rpm motor, during the last three quarters, continue to confirm the feasibility of an efficient and robust motor design.

Energy Conservation and Efficiency Improvement for the Electric Motors Operating in U.S. Oil Fields  

E-Print Network (OSTI)

Because of its versatility, electricity consumption continues to grow all over the world more rapidly than any other energy form. The portion of the United States' primary energy supply used as electricity has expanded from near zero at the turn of the century to 38 percent in 1987. Electric motors use as input about 64% of all electricity in the U.S. and many other countries. The cost of powering motors in the U.S. is estimated to be roughly $90 billion a year. In terms of primary energy input, motor energy use in the U.S. is comparable to all auto energy use. Electric motors are the largest users of energy in all mineral extraction activities. In oil fields, electric motors drive the pumping units used for lifting the oil and water to the surface. To find out actual efficiencies of operating motors in the oil fields, the University of Wyoming and the U.S. Department of Energy -Denver Support Office have been working for the last twelve months on two Naval Petroleum Reserve oil fields -one each in California and Wyoming. So far, actual motor loading of all operating oil fields motors has been determined by actual field measurements. We have also completed the analysis of economy of operation of existing motors and evaluating the candidate replacement motors. In this paper, we will present these results along with the methodologies and protocol developed for motor energy efficiency improvement in oil field applications.

Achieving A Long Term Business Impact by Improving the Energy Effectiveness and Reliability of Electric Motors  

E-Print Network (OSTI)

Over 100,000 electric motors drive the production equipment throughout a large chemical company. The energy-efficiency and reliability of these motors during their entire life have a decided impact on the company's manufacturing costs and production capability. The Corporate Motor Technology Team (CMTT) conceived and led a program to optimize the cost effectiveness and reliability of new motors and developed criteria to determine whether to repair or replace motors that fail. The higher energy efficiency of the electric motors offered by vendors today plays a crucial role in these decisions. The company's current motor specification, procurement, maintenance, repair and replacement practices are vastly improved and consistent across the corporation. The 1995 savings attributed to the higher energy efficiency of over 2000 motors installed the prior year amount to $570,000 and will continue to accrue year after year. So will the savings stemming from lower maintenance cost and reduced downtime.

Oil Field Electrical Energy Savings Through Energy-Efficient Motor Retrofits  

E-Print Network (OSTI)

The Wyoming Electric Motor Training and Testing Center (WEMTTC), in conjunction with the Department of Energy-Denver Support Office and the Naval Petroleum Reserve #3 (NPR-3), has conducted an extensive study of electric motor efficiency at the Reserve's oil field near Casper, Wyoming. As a result of this project, WEMTTC has developed a new test method for estimating an electric motor's operating efficiency, and the instrumentation to implement this test method. Using the new test method and instrumentation, several oversized or inefficient motors were replaced with new generation, high-efficiency motors, and the savings documented. This paper describes the test method and instrumentation developed by WEMTTC. The results obtained from the actual energy-efficient motor retrofits are also presented.

Ultra-Efficient and Power Dense Electric Motors for U. S. Industry  

SciTech Connect

The primary purpose of this project was to combine the ease-of-installation and ease-of-use attributes of industrial induction motors with the low-loss and small size and weight advantages of PM motors to create an ultra-efficient, high power density industrial motor that can be started across-the-line or operated from a standard, Volts/Hertz drive without the need for a rotor position feedback device. PM motor products that are currently available are largely variable speed motors that require a special adjustable speed drive with rotor position feedback. The reduced size and weight helps to offset the magnet cost in order make these motors commercially viable. The scope of this project covers horsepower ratings from 20 ? 500. Prototypes were built and tested at ratings ranging from 30 to 250 HP. Since fans, pumps and compressors make up a large portion of industrial motor applications, the motor characteristics are tailored to those applications. Also, since there is extensive use of adjustable frequency inverters in these applications, there is the opportunity to design for an optimal pole number and operate at other than 60 Hz frequency when inverters are utilized. Designs with four and eight pole configurations were prototyped as part of this work. Four pole motors are the most commonly used configuration in induction motors today. The results of the prototype design, fabrication, and testing were quite successful. The 50 HP rating met all of the design goals including efficiency and power density. Tested values of motor losses at 50 HP were 30% lower than energy efficient induction motors and the motor weight is 35% lower than the energy efficient induction motor of the same rating. Further, when tested at the 30 HP rating that is normally built in this 286T frame size, the efficiency far exceeds the project design goals with 30 HP efficiency levels indicating a 55% reduction in loss compared to energy efficient motors with a motor weight that is a few percentage points lower than the energy efficient motor. This 30 HP rating full load efficiency corresponds to a 46% reduction in loss compared to a 30 HP NEMA Premium? efficient motor. The cost goals were to provide a two year or shorter efficiency-based payback of a price premium associated with the magnet cost in these motors. That goal is based on 24/7 operation with a cost of electricity of 10 cents per kW-hr. Similarly, the 250 HP prototype efficiency testing was quite successful. In this case, the efficiency was maximized with a slightly less aggressive reduction in active material. The measured full load efficiency of 97.6% represents in excess of a 50% loss reduction compared to the equivalent NEMA Premium Efficiency induction motor. The active material weight reduction was a respectable 14.5% figure. This larger rating demonstrated both the scalability of this technology and also the ability to flexibly trade off power density and efficiency. In terms of starting performance, the 30 ? 50 HP prototypes were very extensively tested. The demonstrated capability included the ability to successfully start a load with an inertia of 25 times the motor?s own inertia while accelerating against a load torque following a fan profile at the motor?s full nameplate power rating. This capability will provide very wide applicability of this motor technology. The 250 HP prototype was also tested for starting characteristics, though without a coupled inertia and load torque. As a result it was not definitively proven that the same 25 times the motor?s own inertia could be started and synchronized successfully at 250 HP. Finite element modeling implies that this load could be successfully started, but it has not yet been confirmed by a test.

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

SciTech Connect

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.

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

SciTech Connect

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.

This report describes research performed on the viability of changing the effectively active number of turns in the stator windings of an internal permanent magnet (IPM) electric motor to strengthen or weaken the magnetic fields in order to optimize the motor's performance at specific operating speeds and loads. 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.

Efficient electric motor systems for industry. Report on roundtable discussions of market problems and ways to overcome them  

Science Conference Proceedings (OSTI)

Improving the efficiency of electric motor systems is one of the best energy-saving opportunities for the United States. The Department of Energy (DOE) Office of Industrial Technologies estimates that by the year 2010 in the industrial sector, the opportunities for savings from improved efficiency in electric motor systems could be roughly as follows: 240 billion kilowatthours per year. $13 billion per year from US industry`s energy bill. Up to 50,000 megawatts in new powerplant capacity avoided. Up to 44 million metric tons of carbon-equivalent emissions mitigated per year, corresponding to 3 percent of present US emissions. Recognizing the benefits of this significant opportunity for energy savings, DOE has targeted improvements in the efficiency of electric motor systems as a key initiative in the effort to promote flexibility and efficiency in the way electricity is produced and used. Efficient electric motor systems will help the United States reach its national goals for energy savings and greenhouse gas emission reductions.

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

Science Conference Proceedings (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.

Subcontract Report: Final Report on Assessment of Motor Technologies for Traction Drives of Hybrid and Electric Vehicles (Subcontract #4000080341)  

DOE Green Energy (OSTI)

Currently, interior permanent magnet (IPM) motors with rare-earth (RE) magnets are almost universally used for hybrid and electric vehicles (EVs) because of their superior properties, particularly power density. However, there is now a distinct possibility of limited supply or very high cost of RE magnets that could make IPM motors unavailable or too expensive. Because development of electric motors is a critical part of the U.S. Department of Energy (DOE) Advanced Power Electronics and Motors activity, DOE needs to determine which options should be investigated and what barriers should be addressed. Therefore, in order to provide a basis for deciding which research topics should be pursued, an assessment of various motor technologies was conducted to determine which, if any, is potentially capable of meeting FreedomCAR 2015 and 2020 targets. Highest priority was given to IPM, surface mounted permanent magnet (SPM), induction, and switched reluctance (SR) motors. Also of interest, but with lesser emphasis, were wheel motors, multiple-rotor motors, motors with external excitation, and several others that emerged from the assessment. Cost and power density (from a design perspective, the power density criterion translates to torque density) are emerging as the two most important properties of motors for traction drives in hybrid and EVs, although efficiency and specific power also are very important. The primary approach for this assessment involved interviews with original equipment manufacturers (OEMs), their suppliers, and other technical experts. For each technology, the following issues were discussed: (1) The current state-of-the-art performance and cost; (2) Recent trends in the technology; (3) Inherent characteristics of the motor - which ones limit the ability of the technology to meet the targets and which ones aid in meeting the target; (4) What research and development (R&D) would be needed to meet the targets; and (5) The potential for the technology to meet the targets. The interviews were supplemented with information from past Oak Ridge National Laboratory (ORNL) reports, previous assessments that were conducted in 2004, and literature on magnet technology. The results of the assessment validated the DOE strategy involving three parallel paths: (1) there is enough of a possibility that RE magnets will continue to be available, either from sources outside China or from increased production in China, that development of IPM motors using RE magnets should be continued with emphasis on meeting the cost target. (2) yet the possibility that RE magnets may become unavailable or too expensive justifies efforts to develop innovative designs for permanent magnet (PM) motors that do not use RE magnets. Possible other magnets that may be substituted for RE magnets include samarium-cobalt (Sm-Co), Alnico, and ferrites. Alternatively, efforts to develop motors that do not use PMs but offer attributes similar to IPM motors also are encouraged. (3) New magnet materials using new alloys or processing techniques that would be less expensive or have comparable or superior properties to existing materials should be developed if possible. IPM motors are by far the most popular choice for hybrid and EVs because of their high power density, specific power, and constant power-speed ratio (CPSR). Performance of these motors is optimized when the strongest possible magnets - i.e., RE neodymium-iron-boron (NdFeB) magnets - are used.

Transistors for Electric Motor Drives: High-Performance GaN HEMT Modules for Agile Power Electronics  

SciTech Connect

ADEPT Project: Transphorm is developing transistors with gallium nitride (GaN) semiconductors that could be used to make cost-effective, high-performance power converters for a variety of applications, including electric motor drives which transmit power to a motor. A transistor acts like a switch, controlling the electrical energy that flows around an electrical circuit. Most transistors today use low-cost silicon semiconductors to conduct electrical energy, but silicon transistors donít operate efficiently at high speeds and voltage levels. Transphorm is using GaN as a semiconductor material in its transistors because GaN performs better at higher voltages and frequencies, and it is more energy efficient than straight silicon. However, Transphorm is using inexpensive silicon as a base to help keep costs low. The company is also packaging its transistors with other electrical components that can operate quickly and efficiently at high power levelsóincreasing the overall efficiency of both the transistor and the entire motor drive.

PM Motor Parametric Design Analyses for Hybrid Electric Vehicle Traction Drive Application: Interim Report  

DOE Green Energy (OSTI)

The Department of Energy's (DOE) Office of FreedomCAR (Cooperative Automotive Research) and Vehicle Technologies has a strong interest in making rapid progress in permanent magnet (PM) machine development. The program is directing various technology development projects that will advance the technology and lead to request for proposals (RFP) for manufacturer prototypes. 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 to determine the effects of design parameters, 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 interim progress report summarizes the results of these activities as of June 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, 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 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 power density surpassed by no other machine design.

The experimental implementation and comparison of active, semiactive, and passive vehicle suspensions utilizing a linear electric motor  

E-Print Network (OSTI)

The primary objective of this research is the investigation of the experimental implementation of an active automobile suspension, three types of semiactive suspensions, and a passive suspension. These suspensions are realized via computer control of a linear electric motor. The details of the suspensions are explained in full assuming no prior knowledge by the reader. A theoretical quarter car model is developed and used to provide baseline performance criteria. Details of the design and development of the experimental test rig are given. The experimental results are compared to the theoretical results to study the effectiveness of the motor at realizing the control strategies. This gives an indication of the feasibility of electric motors for implementation of active and semiactive suspension control strategies. Furthermore, the control algorithms are compared to each other to rate each for performance versus complexity. Also, the experimental results are compared to previous experimental results for a resistance controlled semiactive suspension using dual dampers. The experimental test rig and theoretical simulation results agreed fairly well for all suspension performance criteria. The relative comparisons of each suspension when implemented on the test rig were almost identical to the rankings resulting from theory. The performance criteria showed that an active suspension is substantially better than a passive one. Also, only minimal differences exist between the active suspension and the three semiactive suspensions. This indicates that an active suspension is not needed for excellent suspension performance.

Cost Effective, High Efficiency Integrated Systems Approach to Auxilliary Electric Motors  

DOE Green Energy (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.

Discrimination among mechanical fault types in induction motors using electrical measurements  

E-Print Network (OSTI)

Rotating machine failures are a major cause of downtime in a wide variety of industrial processes and are a burden on maintenance personnel and facilities. Some of these failures occur suddenly and are seemingly unpredictable. However, the overwhelming majority develop slowly over time and produce characteristic warning signs. A system capable of detecting and diagnosing these incipient faults before they become critical would significantly reduce downtime and serve to facilitate maintenance and repair of these machines. The ability to accurately distinguish between different types of incipient faults would be a critical aspect of such a system. In this research, a model-based method for diagnosing motor faults is examined and tested using two squirrel-cage AC induction motors with staged fault conditions. The proposed method involves the multi-resolution signal analysis of the current residuals. These residuals are generated by comparing the measured motor current with the current predicted by a recurrent neural network. The frequency content of the distortion of the residuals is used to identify the type of fault present. Although "steady-state" conditions are examined exclusively in this research, the nonstationarities of the current signals are sufficient to warrant the use of multi-resolution analysis. The fault diagnosis system is tested using data taken from an 800 hp motor and a 3 hp motor. The method is successful in identifying residual distortion in the frequency range expected for broken-bar faults. Because the magnitude of the distortion grows with increasing fault severity, the method is also useful for evaluating fault severity for broken-bar faults. However, the current distortions caused by rotor eccentricities and damaged bearings are too small to be identified in a statistically significant manner using this approach. Nevertheless, this research demonstrates the feasibility of a general method by which the characteristic frequencies produced by a particular type of fault can be identified in the output of a system.

Electrostatic generator/motor having rotors of varying thickness and a central stator electrically connected together into two groups  

DOE Patents (OSTI)

A sub-module consists of a set of two outer sets of stationary fan-blade-shaped sectors. These outer sectors include conductive material and are maintained at ground potential in several examples. Located midway between them is a set of stationary sector plates with each plate being electrically insulated from the others. An example provides that the inner sector plates are connected together alternately, forming two groups of parallel-connected condensers that are then separately connected, through high charging circuit resistances, to a source of DC potential with respect to ground, with an additional connecting lead being provided for each group to connect their output as an AC output to a load. These same leads can he used, when connected to a driver circuit, to produce motor action.

Performance Evaluation of a Cascaded H-Bridge Multi Level Inverter Fed BLDC Motor Drive in an Electric Vehicle  

E-Print Network (OSTI)

The automobile industry is moving fast towards Electric Vehicles (EV); however this paradigm shift is currently making its smooth transition through the phase of Hybrid Electric Vehicles. There is an ever-growing need for integration of hybrid energy sources especially for vehicular applications. Different energy sources such as batteries, ultra-capacitors, fuel cells etc. are available. Usage of these varied energy sources alone or together in different combinations in automobiles requires advanced power electronic circuits and control methodologies. An exhaustive literature survey has been carried out to study the power electronic converter, switching modulation strategy to be employed and the particular machine to be used in an EV. Adequate amount of effort has been put into designing the vehicle specifications. Owing to stronger demand for higher performance and torque response in an EV, the Permanent Magnet Synchronous Machine has been favored over the traditional Induction Machine. The aim of this thesis is to demonstrate the use of a multi level inverter fed Brush Less Direct Current (BLDC) motor in a field oriented control fashion in an EV and make it follow a given drive cycle. The switching operation and control of a multi level inverter for specific power level and desired performance characteristics is investigated. The EV has been designed from scratch taking into consideration the various factors such as mass, coefficients of aerodynamic drag and air friction, tire radius etc. The design parameters are meant to meet the requirements of a commercial car. The various advantages of a multi level inverter fed PMSM have been demonstrated and an exhaustive performance evaluation has been done. The investigation is done by testing the designed system on a standard drive cycle, New York urban driving cycle. This highly transient driving cycle is particularly used because it provides rapidly changing acceleration and deceleration curves. Furthermore, the evaluation of the system under fault conditions is also done. It is demonstrated that the system is stable and has a ride-through capability under different fault conditions. The simulations have been carried out in MATLAB and Simulink, while some preliminary studies involving switching losses of the converter were done in PSIM.

Two-way coupling of Presto v2.8 and CTH v8.1.  

SciTech Connect

A loose two-way coupling of SNL's Presto v2.8 and CTH v8.1 analysis code has been developed to support the analysis of explosive loading of structures. Presto is a Lagrangian, three-dimensional explicit, transient dynamics code in the SIERRA mechanics suite for the analysis of structures subjected to impact-like loads. CTH is a hydro code for modeling complex multi-dimensional, multi-material problems that are characterized by large deformations and/or strong shocks. A fundamental assumption in this loose coupling is that the compliance of the structure modeled with Presto is significantly smaller than the compliance of the surrounding medium (e.g. air) modeled with CTH. A current limitation of the coupled code is that the interaction between CTH and thin structures modeled in Presto (e.g. shells) is not supported. Research is in progress to relax this thin-structure limitation.

Ontario Hydro Motor Efficiency Study  

E-Print Network (OSTI)

Electric motors consume more than one-half of the electrical energy produced by Ontario Hydro. In the residential sector, the major motor load is for refrigerators and freezers while packaged equipment dominate the motor load in the commercial market. However, this paper concentrates on the industrial market since 76% of this market's load is motors. The poly phase integral horsepower motor is the "workhorse" of industry. The efficiency of the standard induction motor can be improved. The new "high efficiency" motor is described and the operating cost is compared to the standard motor. Payback for high efficiency motors is found to be about one year for continuous duty applications. Specific instructions are presented for use in industry.

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, √?¬?√?¬?√?¬?√?¬?√?¬?√?¬?√?¬?√?¬Ę√?¬?√?¬?√?¬?√?¬?√?¬?√?¬?√?¬?√?¬?√?¬?√?¬?√?¬?√?¬?√?¬?√?¬?√?¬?√?¬?Motors and Generators for the 21st Century√?¬?√?¬?√?¬?√?¬?√?¬?√?¬?√?¬?√?¬Ę√?¬?√?¬?√?¬?√?¬?√?¬?√?¬?√?¬?√?¬?√?¬?√?¬?√?¬?√?¬?√?¬?√?¬?√?¬?√?¬Ě. 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.

Using MotorMaster to Track Motor Inventory and Analyze Purchasing Decisions  

E-Print Network (OSTI)

MotorMaster 4.0 can be a useful software package for electric motor management decisions in industrial facilities. To be successful, the MotorMaster database must be populated with detailed motor nameplate information. Georgia Tech worked with a large, motor intensive chemical manufacturing plant to collect motor nameplate information on motors 60 hp or larger and populate the motor database. Approximately 130 motors were identified and surveyed. The completed motor database is used to track maintenance actions and to analyze motor replacement options. The approach used to secure and enter motor nameplate data along with examples of purchasing analyses completed will be presented. The success of the MotorMaster software with large motors has convinced the firm to expand its use to smaller horsepower motors.

Gasoline and Diesel Fuel Update (EIA)

1 1 Overview The natural gas industry and markets experienced a num- ber of key changes during 2001. After two years of in- crease, consumption declined in 2001 in all sectors except electric power. Production and net imports increased by 716 Bcf, but much of this supply was added to storage. Prices were generally higher in 2001 compared with previ- ous years. The average wellhead price was $4.02 per thousand cubic feet (Mcf), which is 9 percent above the 2000 level and 84 percent above the 1999 level. However, wellhead prices declined throughout the year. Beyond the changes in market activities, the 2001 data re- flect recent changes in the industry accounting employed by the Energy Information Administration (EIA). EIA has reclassified gas use in the electricity sector to reflect to- day's less regulated energy market. Regulatory reform in both natural gas and electricity markets during

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.

In the petrochemical and refining Industries, and most manufacturing plants, the reliable operation of AC motors always has been crucial to the continuous operation of the process. Now, the cost of operating these motors has also become a significant factor. Engineers Involved In motor specification can help lower plant operating costs and reduce electrical energy consumption dramatically by a relatively simple technique: retrofit of existing, standard-efficiency motors with new, high efficiency models. This article demonstrates strong reasons for motor retrofit, and explains step-by step how process and manufacturing engineering personnel can fully evaluate a retrofit decision.

Motor Energy Saving Opportunities in an Industrial Plant  

E-Print Network (OSTI)

Industrial plants have enormous energy saving opportunities with electric motors. Improving motor efficiency is a conventional wisdom to save energy. Re-engineering affords far greater savings opportunities than motor efficiency improvement. Motor energy saving techniques and basics are discussed. A case study is presented where 63% motor energy savings were realized.

A Novel Approach to Determining Motor Load  

E-Print Network (OSTI)

Properly sized electric motors are essential if industrial plant efficiency is to be optimized and energy costs minimized. Because of the difficulty in making power measurements on three phase motors, loading is rarely, if ever, checked. A simple indication of motor load can be achieved by measuring operating speed because speed and load are almost linearly related. The decrease in motor speed from no load conditions, referred to as slip, can be determined with a non-contact, optical tachometer. Field measurements of motor slip were conducted at a textile plant to quantify motor load conditions. To verify the relationship between operating speed and load, measurements of motor power consumption on a representative number of motors were also conducted. The results of the motor survey, including number of motors, size, and load, are summarized in this paper along with an estimate of the savings from replacing oversized motors.

This results in higher consumption than previously would have been the case. Total natural gas consumption fell to 22.2 trillion cubic feet (Tcf) from the record high of 23.3 Tcf in 2000, with a corresponding decline in the volume delivered to end users from 21.5 to 20.5 Tcf. In general, higher prices likely discouraged consumption. Residential and commercial consumption declined for the year, reflecting the influence of weather on these sectors (Figure 1).

City gate prices represent the total cost paid by gas distribution companies for gas received at the point where gas is physically transferred from a pipeline company or transmission system to the local distribution company (LDC). This price reflects all charges for the com- modity, storage, and transportation associated with the LDC obtaining natural gas for sale to consumers. · Residential prices in 2001 matched their previous record high, while prices to the other sectors were at their highest since

Conducting a Motor Survey: Key Step for Establishing a Motor Management Policy  

E-Print Network (OSTI)

Roughly 70% of the energy consumed by manufacturing processes is used by electric motors. According to the U.S. Department of Energy, greater attention to motor systems management can reduce motor-related energy costs by 18%. Establishing a motor management policy is therefore an essential task for any plant manager or engineer concerned with minimizing motor (and process) downtime and reducing energy costs. In order to develop an effective motor policy, a manager needs information on the number and condition of motors in use. A targeted motor survey will collect data on a representative sample of a plant's motor population. This survey information will then provide a basis for further development of the motor policy. This paper discusses the process of conducting a motor survey. It identifies the type of information to be collected, along with a methodology for selecting appropriate sample motors for more detailed investigations.

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.

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  

Science Conference Proceedings (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 todayís 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.

Submersible canned motor mixer pump  

DOE Patents (OSTI)

A mixer pump used in a waste tank for mobilizing high-level radioactive liquid waste having a column assembly containing power cables, a motor housing with electric motor means which includes a stator can of a stator assembly and a rotor can of a rotor assembly, and an impeller assembly with an impeller connected to a shaft of the rotor assembly. The column assembly locates the motor housing with the electric motor means adjacent to the impeller which creates an hydraulic head, and which forces the liquid waste into the motor housing to cool the electric motor means and to lubricate radial and thrust bearing assemblies. Hard-on-hard bearing surfaces of the bearing assemblies and a ring assembly between the impeller and electric motor means act to grind down large particles in the liquid waste flow. These larger particles are received in slots in the static bearing members of the radial bearing assemblies. Only solid waste particles smaller than the clearances in the system can pass therethrough, thereby resisting damage to and the interruption of the operation of the mixer pump.

The escalating cost of electric power coupled with the rapid depletion of our non-renewable resources makes consideration of motor efficiency good sense both from economic and conservation viewpoints. The efficiency of an electric motor can be assessed during bid evaluation by applying loss penalties: however, the actual value can be influenced at an earlier stage by a careful review of what goes into the motor specification.

DOE Patents (OSTI)

A method and apparatus for assessing the efficiency of an in-service motor. The operating characteristics of the in-service motor are remotely measured. The operating characteristics are then applied to an equivalent circuit for electrical motors. Finally the equivalent circuit is evaluated to determine the performance characteristics of said in-service motor. Based upon the evaluation an individual is able to determine the rotor speed, power output, efficiency, and toque of the in-service motor. Additionally, an individual is able to confirm the calculations by comparing measured values with values obtained as a result of the motor equivalent circuit evaluation.

KELT-2Ab: A HOT JUPITER TRANSITING THE BRIGHT (V = 8.77) PRIMARY STAR OF A BINARY SYSTEM  

Science Conference Proceedings (OSTI)

We report the discovery of KELT-2Ab, a hot Jupiter transiting the bright (V = 8.77) primary star of the HD 42176 binary system. The host is a slightly evolved late F-star likely in the very short-lived 'blue-hook' stage of evolution, with T{sub eff} = 6148 {+-} 48 K, log g = 4.030{sup +0.015}{sub -0.026} and [Fe/H] = 0.034 {+-} 0.78. The inferred stellar mass is M{sub *} = 1.314{sup +0.063}{sub -0.060} M{sub Sun} and the star has a relatively large radius of R{sub *} = 1.836{sup +0.066}{sub -0.046} R{sub Sun }. The planet is a typical hot Jupiter with period 4.1137913 {+-} 0.00001 days and a mass of M{sub P} = 1.524 {+-} 0.088 M{sub J} and radius of R{sub P} = 1.290{sup +0.064}{sub -0.050} R{sub J}. This is mildly inflated as compared to models of irradiated giant planets at the {approx}4 Gyr age of the system. KELT-2A is the third brightest star with a transiting planet identified by ground-based transit surveys, and the ninth brightest star overall with a transiting planet. KELT-2Ab's mass and radius are unique among the subset of planets with V McLaughlin measurements, which should have an amplitude of {approx}44 m s{sup -1}.

Reduced vibration motor winding arrangement  

DOE Patents (OSTI)

The present invention relates generally to an electric motor winding and, more particularly, to a three phase motor armature winding arrangement designed to reduce motor vibration and improve efficiency. An individual phase winding arrangement having a sixty electrical degree phase belt width for use with a three phase motor armature includes a delta connected phase winding portion and a wye connected phase winding portion. Both the delta and wye connected phase winding portions have a thirty electrical degree phase belt width. The delta and wye connected phase winding portions are each formed from a preselected number of individual coils each formed, in turn, from an unequal number of electrical conductor turns in the approximate ratio of {radical}3. The individual coils of the delta and wye connected phase winding portions may either be connected in series or parallel. This arrangement provides an armature winding for a three phase motor which retains the benefits of the widely known and utilized thirty degree phase belt concept, including improved mmf waveform and fundamental distribution factor.

A motor current noise signature analysis method 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 inaccessible or hostile environments. 6 figs.

Total Economics of Energy Efficient Motors  

E-Print Network (OSTI)

Due to the large increases in cost of electrical energy in recent years, the energy savings attainable with the use of energy-efficient motors is very attractive to all motor users. But energy and electric demand charge savings tell only part of the story. Engineers responsible for the selection of motors for many varying uses must also consider many less tangible factors when deciding whether a price premium for an energy-efficient motor is justified. These important intangible factors may throw a borderline decision in favor of a premium motor; at other times these factors may dictate that the capital money could be spent more wisely in other areas. This paper will point out those factors which effect the decision of whether or not to buy a premium priced energy-efficient motor or a standard electric motor. It will also address the question of whether it is cost-effective to rewind an old motor which has failed or to replace it with a new energy-efficient motor.

TFTR Motor Generator  

SciTech Connect

A general description is given of 475 MVA pulsed motor generators for TFTR at Princeton Plasma Physics Laboratory. Two identical generators operating in parallel are capable of supplying 950 MVA for an equivalent square pulse of 6.77 seconds and 4,500 MJ at 0.7 power factor to provide the energy for the pulsed electrical coils and heating system for TFTR. The description includes the operational features of the 15,000 HP wound rotor motors driving each generator with its starting equipment and cycloconverter for controlling speed, power factor, and regulating line voltage during load pulsing where the generator speed changes from 87.5 to 60 Hz frequency variation to provide the 4,500 MJ or energy. The special design characteristics such as fatigue stress calculations for 10/sup 6/ cycles of operation, forcing factor on exciter to provide regulation, and low generator impedance are reviewed.

A piezoelectric motor having a stator in which piezoelectric elements are contained in slots formed in the stator transverse to the desired wave motion. When an electric field is imposed on the elements, deformation of the elements imposes a force perpendicular to the sides of the slot, deforming the stator. Appropriate frequency and phase shifting of the electric field will produce a wave in the stator and motion in a rotor. In a preferred aspect, the piezoelectric elements are configured so that deformation of the elements in direction of an imposed electric field, generally referred to as the d.sub.33 direction, is utilized to produce wave motion in the stator. In a further aspect, the elements are compressed into the slots so as to minimize tensile stresses on the elements in use.

Reduced vibration motor winding arrangement  

DOE Patents (OSTI)

An individual phase winding arrangement having a sixty electrical degree phase belt width for use with a three phase motor armature includes a delta connected phase winding portion and a wye connected phase winding portion. Both the delta and wye connected phase winding portions have a thirty electrical degree phase belt width. The delta and wye connected phase winding portions are each formed from a preselected number of individual coils each formed, in turn, from an unequal number of electrical conductor turns in the approximate ratio of {radical}3. The individual coils of the delta and wye connected phase winding portions may either be connected in series or parallel. This arrangement provides an armature winding for a three phase motor which retains the benefits of the widely known and utilized thirty degree phase belt concept, including improved mmf waveform and fundamental distribution factor, with consequent reduced vibrations and improved efficiency. 4 figs.

Electric turbocompound control system  

DOE Patents (OSTI)

Turbocompound systems can be used to affect engine operation using the energy in exhaust gas that is driving the available turbocharger. A first electrical device acts as a generator in response to turbocharger rotation. A second electrical device acts as a motor to put mechanical power into the engine, typically at the crankshaft. Apparatus, systems, steps, and methods are described to control the generator and motor operations to control the amount of power being recovered. This can control engine operation closer to desirable parameters for given engine-related operating conditions compared to actual. The electrical devices can also operate in "reverse," going between motor and generator functions. This permits the electrical device associated with the crankshaft to drive the electrical device associated with the turbocharger as a motor, overcoming deficient engine operating conditions such as associated with turbocharger lag.

Electric vehicles  

SciTech Connect

Quiet, clean, and efficient, electric vehicles (EVs) may someday become a practical mode of transportation for the general public. Electric vehicles can provide many advantages for the nation's environment and energy supply because they run on electricity, which can be produced from many sources of energy such as coal, natural gas, uranium, and hydropower. These vehicles offer fuel versatility to the transportation sector, which depends almost solely on oil for its energy needs. Electric vehicles are any mode of transportation operated by a motor that receives electricity from a battery or fuel cell. EVs come in all shapes and sizes and may be used for different tasks. Some EVs are small and simple, such as golf carts and electric wheel chairs. Others are larger and more complex, such as automobile and vans. Some EVs, such as fork lifts, are used in industries. In this fact sheet, we will discuss mostly automobiles and vans. There are also variations on electric vehicles, such as hybrid vehicles and solar-powered vehicles. Hybrid vehicles use electricity as their primary source of energy, however, they also use a backup source of energy, such as gasoline, methanol or ethanol. Solar-powered vehicles are electric vehicles that use photovoltaic cells (cells that convert solar energy to electricity) rather than utility-supplied electricity to recharge the batteries. This paper discusses these concepts.

Developing a Motor Management Policy at BASF  

E-Print Network (OSTI)

In early 1998 Thomas R. Theising, BASF Corporate Engineering initiated the formation of a motor management team. The goal of the team was to develop a Motor Management Guideline to better manage the purchase and repair of motors used throughout the company. BASF draws a 240MW electrical power load. Accepting that 70% (industry standards range from 63 to 75% for BASF's businesses) of this load was consumed by rotating equipment and assuming an average cost of$401MWh at 8400 hours of annual operation BASF spends over $56M annually to operate electric motors. A guideline to better manage the purchase and repair of these motors could reduce this operating cost by 3 to 5%, which translates to $1.7M to $2.8M annually. An estimated total cost to BASF for implementation is $200K. The development of a Motor Management Guideline required the cooperative effort of a team of individuals. This team consisted of representatives from several BASF manufacturing locations, Corporate Engineering, Corporate Purchasing and Energy Management. Also, BASF included representatives from Duke Power and from Advanced Energy (AE). Advanced Energy had previously provided motor testing services to the BASF facility in Enka, NC.

Energy Savings of Variable Speed Motors  

E-Print Network (OSTI)

This paper investigates the energy savings available by utilizing variable speed motors on pump and fan applications. Conventional control of flow or pressure in process plants is normally accomplished by throttling the various streams with control valves. Depending on the system and the actual operating conditions, this throttling may consume a considerable amount of energy. The hydraulics of different systems are investigated to generalize high energy saving applications. Typical pump characteristics at varying speeds are investigated since most performance curves are only available at a constant speed. The various types of variable speed electric motors are discussed. However, the primary variable speed system recommended is a variable frequency speed system which utilizes standard induction motors. Specific cases of centrifugal pump applications and cooling tower fan service are presented. Turndown frequencies, stream factors, and electric rates are included in the evaluation. The energy savings of a variable speed system becomes significant when flow rates vary widely and the electrical rates are high.

Copper in the Rotor for Lighter, Longer Lasting Motors  

E-Print Network (OSTI)

This paper reviews the advantages of substituting die-cast copper for aluminum in the motor rotor. This advance in motor technology has been long sought by the motor industry but short die life due to the high melting point of copper frustrated attempts to manufacture by pressure die casting. The nickel-base alloy hot die technology developed to solve the manufacturing problem is briefly reviewed. Development work done prior to the present program and commercial motors derived from that work have focused on the increased electrical energy efficiency achievable by using copper with its higher electrical conductivity in the rotor. Performance characteristics of example industrial motors are presented. Modification of the conductor bar shape to control in-rush current and starting torque to accommodate copper in the rotor will be discussed. Modeling by motor manufacturers has shown that by using copper in the rotor, a lighter motor than an aluminum rotor motor at the same efficiency can be built. An example of weight savings calculated for a 15 Hp (11 kW) motor is presented. Data presented here show that motors with copper rotors run cooler. Industry experience shows that cooler operation translates to reduced maintenance costs, improved reliability and longer motor life.

3M's Motor Challenge Showcase Demonstration Project  

E-Print Network (OSTI)

In January 1994, 3M began the task of optimizing the electric motor systems at 3M Center, a 26 building, 7 million square foot corporate campus. A cross-functional, cross-company team was established which included four 3M employees representing two different departments within 3M, an engineer specializing in demand side management programs from Northern States Power Company, and a sales engineer from General Electric Supply Company. The team was later joined by an engineering specialist from Landis & Staefa, Inc., a building automation controls supplier. The team began the task of identifying the projects that could save energy and provide a reasonable return on 3M's investment on a building by building approach. As surveys were completed, proposals were prepared and presented to management requesting funding. The team continued the process of identifying projects in remaining buildings and took on the responsibility of designing, contracting and implementing projects as funding was approved for those already studied. Follow-up measurements to ascertain that the savings predicted was actually achieved are done before project close-out. This project was submitted and accepted as a Motor Challenge Showcase Demonstration Project. The Motor Challenge is a U.S. Department of Energy initiative to promote the efficient use of energy in electric motor systems. Showcase Demonstration Projects are used to exemplify the benefits that motor system optimization can provide. This Showcase Project is different from most as it emphasizes the process that was developed to carry out a project of this magnitude rather than any single specific technologies or applications. The team has completed the project at 3M Center. Measured savings are $823,000 per year.

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

Modular PM Motor Drives for Automotive Traction Applications  

DOE Green Energy (OSTI)

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

Report on Toyota Prius Motor Thermal Management  

DOE Green Energy (OSTI)

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

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.

Advanced Ultra-High Speed Motor for Drilling  

Science Conference Proceedings (OSTI)

Three (3) designs have been made for two sizes, 6.91 cm (2.72 inch) and 4.29 cm (1.69 inch) outer diameters, of a patented inverted configured Permanent Magnet Synchronous Machines (PMSM) electric motor specifically for drilling at ultra-high rotational speeds (10,000 rpm) and that can utilize advanced drilling methods. Benefits of these motors are stackable power sections, full control (speed and direction) of downhole motors, flow hydraulics independent of motor operation, application of advanced drilling methods (water jetting and abrasive slurry jetting), and the ability of signal/power electric wires through motor(s). Key features of the final designed motors are: fixed non-rotating shaft with stator coils attached; rotating housing with permanent magnet (PM) rotor attached; bit attached to rotating housing; internal channel(s) in a nonrotating shaft; electric components that are hydrostatically isolated from high internal pressure circulating fluids ('muds') by static metal to metal seals; liquid filled motor with smoothed features for minimized turbulence in the motor during operation; and new inverted coated metal-metal hydrodynamic bearings and seals. PMSM, Induction and Switched Reluctance Machines (SRM), all pulse modulated, were considered, but PMSM were determined to provide the highest power density for the shortest motors. Both radial and axial electric PMSM driven motors were designed with axial designs deemed more rugged for ultra-high speed, drilling applications. The 6.91 cm (2.72 inch) OD axial inverted motor can generate 4.18KW (5.61 Hp) power at 10,000 rpm with a 4 Nm (2.95 ft-lbs) of torque for every 30.48 cm (12 inches) of power section. The 6.91 cm (2.72 inch) OD radial inverted motor can generate 5.03 KW (6.74 Hp) with 4.8 Nm (3.54 ft-lb) torque at 10,000 rpm for every 30.48 cm (12 inches) of power section. The 4.29 cm (1.69 inch) OD radial inverted motor can generate 2.56 KW (3.43 Hp) power with 2.44 Nm (1.8 ft-lb) torque at full speed 10,000 rpm for every 30.48 cm (12 inches) of power section. Operating conditions are 300 voltage AC at the motor leads. Power voltage losses in the cables/wirelines to the motor(s) are expected to be about 10% for 5000 feet carrying 2 amperes. Higher voltages and better insulators can lower these losses and carry more amperes. Cutting elements for such high tip velocities are currently not available, consequently these motors will not be built at this time. However, 7.62 cm (3 inch) OD, low speed, PMSM radial electric motors based on this project design are being built under a 2006 Oklahoma Center for the Advancement of Science and Technology 'proof of concept' grant.

Corona and Motor Voltage Interim Report  

SciTech Connect

It has been suggested that to meet the FreedomCAR objectives for cost, size, weight, efficiency, and reliability higher buss voltages be utilized in HEV and FC automotive applications. The reasoning is that since electric power is equal to the product of voltage and current for a given power a higher voltage and lower current would result in smaller cable and inverter switching components. Consequently, the system can be lighter and smaller. On the other hand, higher voltages are known to require better and thicker electrical insulation that reduce the available slot area for motor windings. One cause of slow insulation breakdown is corona that gradually erodes the insulation and shortens the life expectancy of the motor. This study reports on the results of a study on corona initiating voltages for mush-wound and bobbin-wound stators. A unique testing method is illustrated.

Markov Process of Muscle Motors  

E-Print Network (OSTI)

We study a Markov random process describing a muscle molecular motor behavior. Every motor is either bound up with a thin filament or unbound. In the bound state the motor creates a force proportional to its displacement from the neutral position. In both states the motor spend an exponential time depending on the state. The thin filament moves at its velocity proportional to average of all displacements of all motors. We assume that the time which a motor stays at the bound state does not depend on its displacement. Then one can find an exact solution of a non-linear equation appearing in the limit of infinite number of the motors.

These coils are divided into two groups. When these groups are connected such that their magnetomotive forces are additive, two pole motor operation results. When the polarity of one of the groups is then reversed, six pole motor operation results. An auxiliary stator winding which is similar to the main stator winding is displaced from the main stator winding by 90 electrical degrees on a two pole basis. 12 figs.

Simple cost model for EV traction motors  

DOE Green Energy (OSTI)

A simple cost model has been developed that allows the calculation of the OEM cost of electric traction motors of three different types, normalized as a function of power in order to accommodate different power and size. The model includes enough information on the various elements integrated in the motors to allow analysis of individual components and to factor-in the effects of changes in commodities prices. A scalable cost model for each of the main components of an electric vehicle (EV) is a useful tool that can have direct application in computer simulation or in parametric studies. For the cost model to have wide usefulness, it needs to be valid for a range of values of some parameter that determines the magnitude or size of the component. For instance, in the case of batteries, size may be determined by energy capacity, usually expressed in kilowatt-hours (kWh), while in the case of traction motors, size is better determined by rated power, usually expressed in kilowatts (kW). The simplest case is when the cost of the component in question is a direct function of its size; then cost is simply the product of its specific cost ($/unit size) and the number of units (size) in the vehicle in question. Batteries usually fall in this category (cost = energy capacity x $/kWh). But cost is not always linear with size or magnitude; motors (and controllers), for instance, become relatively less expensive as power rating increases. Traction motors, one of the main components for EV powertrains are examined in this paper, and a simplified cost model is developed for the three most popular design variations.

Low-cost motor drive embedded fault diagnosis systems  

E-Print Network (OSTI)

Electric motors are used widely in industrial manufacturing plants. Bearing faults, insulation faults, and rotor faults are the major causes of electric motor failures. Based on the line current analysis, this dissertation mainly deals with the low cost incipient fault detection of inverter-fed driven motors. Basically, low order inverter harmonics contributions to fault diagnosis, a motor drive embedded condition monitoring method, analysis of motor fault signatures in noisy line current, and a few specific applications of proposed methods are studied in detail. First, the effects of inverter harmonics on motor current fault signatures are analyzed in detail. The introduced fault signatures due to harmonics provide additional information about the motor faults and enhance the reliability of fault decisions. It is theoretically and experimentally shown that the extended fault signatures caused by the inverter harmonics are similar and comparable to those generated by the fundamental harmonic on the line current. In the next chapter, the reference frame theory is proposed as a powerful toolbox to find the exact magnitude and phase quantities of specific fault signatures in real time. The faulty motors are experimentally tested both offline, using data acquisition system, and online, employing the TMS320F2812 DSP to prove the effectiveness of the proposed tool. In addition to reference frame theory, another digital signal processor (DSP)-based phasesensitive motor fault signature detection is presented in the following chapter. This method has a powerful line current noise suppression capability while detecting the fault signatures. It is experimentally shown that the proposed method can determine the normalized magnitude and phase information of the fault signatures even in the presence of significant noise. Finally, a signal processing based fault diagnosis scheme for on-board diagnosis of rotor asymmetry at start-up and idle mode is presented. It is quite challenging to obtain these regular test conditions for long enough time during daily vehicle operations. In addition, automobile vibrations cause a non-uniform air-gap motor operation which directly affects the inductances of electric motor and results quite noisy current spectrum. The proposed method overcomes the challenges like aforementioned ones simply by testing the rotor asymmetry at zero speed.

Retail Motor Gasoline Prices*  

Gasoline and Diesel Fuel Update (EIA)

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

Motor gasolines, Summer 1982  

Science Conference Proceedings (OSTI)

The samples were collected from service stations throughout the country and were analyzed in the laboratories of various refiners, motor manufacturers, and chemical companies. The analytical data for 796 samples of motor gasoline, were submitted to the Bartlesville Energy Technology Center for study, necessary calculations, and compilation under a cooperative agreement between the Bartlesville Energy Technology Center (BETC) and the American Petroleum Institute (API). They represent the products of 22 companies, large and small, which manufacture and supply gasoline. These data are tabulated by groups according to brands (unlabeled) and grades for 17 marketing districts into which the country is divided. A map included in this report, shows marketing areas, districts and sampling locations. The report also includes charts indicating the trends of selected properties of motor fuels since 1959. Sixteen octane distribution percent charts for areas 1, 2, 3, and 4 for unleaded antiknock index (R + M)/2 below 90.0, unleaded antiknock index (R + M)/2 90.0 and above, leaded antiknock index (R + M)/2 below 93.0, and leaded antiknock index (R + M)/2 93.0 and above grades of gasoline are presented in this report. The antiknock (octane) index (R + M)/2 averages of gasoline sold in this country were 87.3 for unleaded below 90.0, 91.7 for unleaded 90.0 and above, 89.0 for leaded below 93.0, and no data in this report for 93.0 and above grades of leaded gasoline.

Cooling Tower Fan Motor Power Optimization Study  

Science Conference Proceedings (OSTI)

Cooling towers are in use at more than 200 major electric generating plants in the United States, representing approximately 800 units and a total of more than 210,000 MW. The auxiliary power consumed by cooling tower fan motors can significantly reduce the net power output of steam-cycle power plants. Cooling tower specifications are established by the economic and operational requirements of maximum unit load and the most demanding environmental conditions expected in the towerís locale. Since power pl...
