Download or read book Energy Efficiency Improvements in Electric Motors and Drives written by Anibal de Almeida and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 517 pages. Available in PDF, EPUB and Kindle. Book excerpt: The reduction of energy consumption through improvements in energy efficiency has become an important goal for all countries, in order to improve the efficiency of the economy, to increase energy supply security, and to reduce the emissions of CO and other pollutants caused by power· generation. 2 Electric motors use over half of all electricity consumed in developed countries. Typically 60-80% of the electricity which is used in the industrial sector and about 35% of the electricity used in the commercial sector in the European Union is consumed by motors. In industry, a motor consumes an annual quantity of electricity which corresponds to approximately 5 times its purchase price, throughout its whole life of aroun~ 12 to 20 years. Motors are by far the most important type of electric load. They are used in all sectors and in a wide range of applications, namely the following: fans, compressors, pumps, mills, winders, elevators, transports, home appliances, and office equipment, etc. It is their wide use that makes motor drive systems one of the main targets to achieve significant energy savings. As motors are the largest USers of electrical energy, even small efficiency improvements will produce very large energy savings.

Book Synopsis Energy-efficient Motor Systems by : Steven Nadel
Download or read book Energy-efficient Motor Systems written by Steven Nadel and published by . This book was released on 1991 with total page 418 pages. Available in PDF, EPUB and Kindle. Book excerpt: Motors use more than half of all electricity. This book outlines an approach for increasing motor and motor system efficiency through high-efficiency motors, optimized controls, improved component sizing and repair, better transmission hardware, and more comprehensive monitoring and maintenance. In addition to explaining technical opportunities in language understandable to non-engineers, the book reviews what is known about the existing motor stock and its use, chronicles experience to date with drive power programs and policies, and offers recommendations for future efforts. Full application of the measures described can cut U.S. electricity demand by up to 20 percent, save motor users and utilities billions of dollars, reduce pollutant emissions, and enhance productivity. The book was written by an interdisciplinary team of engineers, energy analysts, and program planners who collectively have over 50 years of experience in the energy efficiency field.

Book Synopsis 20 Ways to Optimize Efficiency in the Use of Induction Motors by : A. Bhatia
Download or read book 20 Ways to Optimize Efficiency in the Use of Induction Motors written by A. Bhatia and published by CreateSpace. This book was released on 2015-02-24 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: The majority of electrical energy consumed in most industrial facilities is used to run electric motors. Annual energy operating costs of electric motors usually far exceed purchase prices. For example, a typical 25 horsepower (hp) motor running at full load for 6,000 hours per year would consume nearly $10,000 of electricity annually. An average purchase price for a motor of this size would be only $500 to $600.Energy efficiency decisions are important decisions that affect operating cost for the life of the equipment. By optimizing the efficiency of your motor-driven systems, you can increase productivity while achieving substantial energy and dollar savings. Opportunities for energy conservation are wide spread and applicable to new as well as old plants. It is important to note that majority of savings shall accrue not on the motor itself but on the motor-driven system as a whole. This 6 - hour Quick Book provides 20 different strategies to guide you into the electric motor evaluation process and highlights common ways you can improve system efficiency and reliability to achieve permanent long-term electric cost reduction. This course is aimed at students, electrical & control engineers, energy auditors, operational & maintenance engineers, contractors and system designers who are responsible for design and operation of the system. Learning ObjectiveAt the conclusion of this course, the reader will understand:• Characteristics, types and classification of motors based on NEMA; • Fixed and variable losses of induction motors; • Power quality and impact of voltage/phase imbalance and power factor on motor performance; • Motor efficiency v/s motor load and motor load v/s speed relationships• Motor load estimation techniques;• Comparison of Energy Efficient v/s Standard Motors; • Cost evaluating methods & simple payback analysis of motor replacement; • Application of variable speed drives on motor energy savings; • Motor transmission efficiency using synchronous belts/soft starters; • Starting systems viz. direct-on-line, delta star controllers; • Motors repair or replacement decisions; • Monitoring and maintenance practices.
Book Synopsis Energy Efficient Motors Reference Guide by : Nadi D. Sadanandan
Download or read book Energy Efficient Motors Reference Guide written by Nadi D. Sadanandan and published by . This book was released on 2005-01 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: Energy efficient motors are motors in which better quality parts, increased conductor size, higher quality steel, and improved design are combined to produce motors with full load efficiencies higher than standard motors. Energy efficient motors maintain high efficiency at low loads. They usually have inherently higher power factors than standard motors and maintain higher power factors under partial load operations. Energy efficient motor windings will generally have longer life than standard motor windings, because they run cooler. This motor reference guide is the result of data and information collected and organized by the Industrial and Large Commercial staff of the Tennessee Valley Authority. Additionally, computer simulations were performed to develop data not currently available in literature. The guide is not intended to be a textbook on motors, but a quick and ready reference to assist in the technical and economic evaluation of energy-efficient motors versus standard motors. However, chapters on motor related topics such as rotating fields, power factor correction and impact of power quality on motor performances have also been included to complement the text.

Book Synopsis Power Quality Issues and Their Impact on the Performance of Industrial Machines by : Abhishek Chauhan
Download or read book Power Quality Issues and Their Impact on the Performance of Industrial Machines written by Abhishek Chauhan and published by Anchor Academic Publishing. This book was released on 2016-10 with total page 49 pages. Available in PDF, EPUB and Kindle. Book excerpt: Power supply quality concerns are the consequences of the increasing use of solid state switching devices, power electronically switched loads, unbalanced power systems, lightning controls, computer and data processing equipment, as well as industrial plant rectifiers and inverters. In this book, special prominence is given to the degrading of power quality due to unbalanced power supply. Moreover, the impact of unbalanced voltage on the performance of three-phase induction motors are also underlined. Three-phase induction motors are broadly used in diverse industrial applications while unbalances in supply voltage are responsible for various ailing impacts on their performance. Furthermore, the variation of performance parameters of three-phase induction motors have been analysed. Additionally, various existing methods for the assessment of the performance induction motor under the supply voltage unbalance have been critically reviewed to underline their shortcomings. The causes, effects, mitigation techniques along with the various interpretations of voltage unbalance, prescribed in different standard, are also discussed to highlight their deficits.
