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.

Handbook of Automotive Power Electronics and Motor Drives by Ali Emadi Pdf

Initially, the only electric loads encountered in an automobile were for lighting and the starter motor. Today, demands on performance, safety, emissions, comfort, convenience, entertainment, and communications have seen the working-in of seemingly innumerable advanced electronic devices. Consequently, vehicle electric systems require larger capacities and more complex configurations to deal with these demands. Covering applications in conventional, hybrid-electric, and electric vehicles, the Handbook of Automotive Power Electronics and Motor Drives provides a comprehensive reference for automotive electrical systems. This authoritative handbook features contributions from an outstanding international panel of experts from industry and academia, highlighting existing and emerging technologies. Divided into five parts, the Handbook of Automotive Power Electronics and Motor Drives offers an overview of automotive power systems, discusses semiconductor devices, sensors, and other components, explains different power electronic converters, examines electric machines and associated drives, and details various advanced electrical loads as well as battery technology for automobile applications. As we seek to answer the call for safer, more efficient, and lower-emission vehicles from regulators and consumer insistence on better performance, comfort, and entertainment, the technologies outlined in this book are vital for engineering advanced vehicles that will satisfy these criteria.

Electric Relays by Vladimir Gurevich Pdf

Electric relays pervade the electronics that dominate our world. They exist in many forms, fulfill many roles, and each have their own behavioral nuances and peculiarities. To date, there exists no comprehensive reference surveying the broad spectrum of electric relays, save one-Electric Relays: Principles and Applications. This ambitious work is not only unique in its scope, but also in its practical approach that focuses on the operational and functional aspects rather than on theory and mathematics. Accomplished engineer Dr. Vladimir Gurevich builds the presentation from first principles, unfolding the concepts and constructions via discussion of their historical development from the earliest ideas to modern technologies. He uses a show-not-tell approach that employs nearly 1300 illustrations and reveals valuable insight based on his extensive experience in the field. The book begins with the basic principles of relay construction and the major functional parts, such as contact and magnetic systems. Then, it devotes individual chapters to the various types of relays. The author describes the principles of function and construction for each type as well as features of several relays belonging to a type that operate on different principles. Remarkably thorough and uniquely practical, Electric Relays: Principles and Applications serves as the perfect introduction to the plethora of electric relays and offers a quick-reference guide for the experienced engineer.

Electrical Contacts by Milenko Braunovic,Nikolai K. Myshkin,Valery V. Konchits Pdf

Various factors affect the performance of electrical contacts, including tribological, mechanical, electrical, and materials aspects. Although these behaviors have been studied for many years, they are not widely used or understood in practice. Combining approaches used across the globe, Electrical Contacts: Fundamentals, Applications, and Technology integrates advances in research and development in the tribological, material, and analytical aspects of electrical contacts with new data on electrical current transfer at the micro- and nanoscales. Taking an application-oriented approach, the authors illustrate how material characteristics, tribological behavior, and loading impact the degradation of contacts, formation of intermetallics, and overall reliability and performance. Coverage is divided broadly into three sections, with the first focused on mechanics, tribology, materials, current and heat transfer, and basic reliability issues of electrical contacts. The next section explores applications, such as power connections, electronic connections, and sliding contacts, while the final section presents the diagnostic and monitoring techniques used to investigate and measure phenomena occurring at electrical contact interfaces. Numerous references to current literature reflect the fact that this book is the most comprehensive survey in the field. Explore an impressive collection of data, theory, and practical applications in Electrical Contacts: Fundamentals, Applications, and Technology, a critical tool for anyone investigating or designing electrical equipment with improved performance and reliability in mind.
