Energy Efficiency Improvements in Electric Motors and Drives by Anibal de Almeida,Paolo Bertoldi,Werner Leonhard Pdf

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.

Energy-efficient Motor Systems by Steven Nadel Pdf

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.

Energy Efficiency Improvements in Electronic Motors and Drives by Paolo Bertoldi,Anibal T. de Almeida,Hugh Falkner Pdf

The 1997 Kyoto Conference defined CO2 emISSIOn targets for the developed regions of the world. The EU target of decreasing the emissions 8% below the 1990 level, by 2010, will require a very substantial effort covering basically all activities if such a target is to be reached. Energy-efficient motor systems can provide one of the most important opportunities to achieve electricity savings in a cost effective way, avoiding at the same time the emission of tens of millions of tons of carbon. The reduction of energy consumption through improvements in energy efficiency is one of the major instruments for developed and developing countries to meet the Kyoto commitments. Energy efficiency is also a key element of the European Union (EU) energy policy, since it improves the efficiency of the economy, increases energy supply security, and decreases harmful emissions due to electricity generation. Electric motor systems use over half of all electricity consumed in developed countries. Typically about 70% of the electricity which is used in the industrial sector and about 35% of the electricity used in the commercial sector in the EU is consumed by motor systems. In industry, a motor on average consumes an annual quantity of electricity which corresponds to approximately 5 times its purchase price, throughout its whole life of around 12 to 20 years.

20 Ways to Optimize Efficiency in the Use of Induction Motors by A. Bhatia Pdf

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.
