The switched reluctance machine (SRM) is the least expensive electrical machine to produce, yet one of the most reliable. As such, research has blossomed during the last decade, and the SRM and variable drive systems using SRMs are receiving considerable attention from industry. Because they require a power electronic converter and controller to function, however, successful realization of an SRM variable drive system demands an understanding of the converter and controller subsystems and their integration with the machine.

Switched Reluctance Motor Drives provides that understanding. It presents a unified view of the machine and its drive system from all of its system and subsystem aspects. With a careful balance of theory and implementation, the author develops the analysis and design of SRMs from first principles, introduces a wide variety of power converters available for driving the SRM, and systematically presents both low- and high-performance controllers. The book includes an in-depth study of acoustic noise and its minimization along with application examples that include comparisons between ac and dc drives and SRM drive.

The result is the first book that provides a state-of-the-art knowledge of SRMs, power converters, and their use with both sensor-based and sensorless controllers. Switched Reluctance Motor Drives enables both students and engineers to learn all aspects of SRM drive systems and appreciate the interdependence of the various subsystems in performance optimization.

Controlling the level of noise in electrical motors is critical to overall system performance. However, predicting noise of an electrical motor is more difficult and less accurate than for other characteristics such as torque-speed. Recent advances have produced powerful computational methods for noise prediction, and Noise of Polyphase Electric Motors is the first book to collect these advances in a single source. It is also the first to include noise prediction for permanent magnet (PM) synchronous motors. Complete coverage of all aspects of electromagnetic, structural, and vibro-acoustic noise makes this a uniquely comprehensive reference. The authors begin with the basic principles of noise generation and radiation, magnetic field and radial forces, torque pulsations, acoustic calculations, as well as noise and vibration of mechanical and acoustic origin. Moving to applications, the book examines in detail stator system vibration analysis including the use of finite element method (FEM) modal analysis; FEM for radial pressure and structural modeling; boundary element methods (BEM) for acoustic radiation; statistical energy analysis (SEA); instrumentation including technologies, procedures, and standards; and both passive and active methods for control of noise and vibration. Noise of Polyphase Electric Motors gathers the fundamental concepts along with all of the analytical, numerical, and statistical methods into a unified reference. It supplies all of the tools necessary to improve the noise performance of electrical motors at the design stage.

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.

This book covers the basics and the state of the art of energy-efficient motor technologies, which can be used now and in the near future to achieve significant and cost-effective energy savings. It describes recent developments in advanced motor technologies such as permanent magnet and reluctance motors. Energy-efficient motor technologies, though enabling a huge amount of electricity to be saved, still have not been widely adopted. The book presents barriers to the adoption of those technologies and features policies to promote the large scale penetration of energy-efficient technologies, describing the experiences carried out so far in different parts of the world. The volume includes contributions from relevant institutions in the European Union, North America, Latin America, Japan and New Zealand.

This volume presents the theory of control systems with sliding mode applied to electrical motors and power converters. It demonstrates the methodology of control design and the original algorithms of control and observation. Practically all semiconductor devices are used in power converters, that feed electrical motors, as power switches. A switching mode offers myriad attractive, inherent properties from a control viewpoint, especially a sliding mode. Sliding mode control supplies high dynamics to systems, invariability of systems to changes of their parameters and of exterior loads in combination with simplicity of design. Unlike linear control, switching sliding mode control does not replace the control system, but uses the natural properties of the control plant system effectively to ensure high control quality. This is the first text that thoroughly describes the application of the highly theoretical control design approach to synchronous drives in practice. It examines in detail the different features of various types of synchronous motors and converters with regard to sliding mode control design. It further presents a detailed analysis of control issues and mechanical coordinate observation design for various types of synchronous motors, of power converters, and various drive control structures. It also discusses the digital implementation of control, observation and identification algorithms. The potential of sliding mode control and observation are moreover demonstrated in numerical and experimental results from real control plants. This work is intended for professionals and advanced students who work in the field of electric drive control. It is also recommended to experts in control theory application, who work with sliding modes for the control of electrical motors and power converters.
