Download or read book Switched Reluctance Motor Drives written by R. Krishnan and published by CRC Press. This book was released on 2017-12-19 with total page 331 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Modern Electrical Drives written by H. Bülent Ertan and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 766 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electrical drives lie at the heart of most industrial processes and make a major contribution to the comfort and high quality products we all take for granted. They provide the controller power needed at all levels, from megawatts in cement production to milliwatts in wrist watches. Other examples are legion, from the domestic kitchen to public utilities. The modern electrical drive is a complex item, comprising a controller, a static converter and an electrical motor. Some can be programmed by the user. Some can communicate with other drives. Semiconductor switches have improved, intelligent power modules have been introduced, all of which means that control techniques can be used now that were unimaginable a decade ago. Nor has the motor side stood still: high-energy permanent magnets, semiconductor switched reluctance motors, silicon micromotor technology, and soft magnetic materials produced by powder technology are all revolutionising the industry. But the electric drive is an enabling technology, so the revolution is rippling throughout the whole of industry.

Download or read book Noise of Polyphase Electric Motors written by Jacek F. Gieras and published by CRC Press. This book was released on 2018-10-03 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Noise and Vibration of Electrical Machines written by and published by North-Holland. This book was released on 1989 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hardbound. Although the basic theory of the noise of electrical machines was elaborated many years ago, the theoretical knowledge has since been considerably extended. This book discusses the acoustics and noise-measuring systems of electrical machines. It is a fully revised English edition of the authors' book published in Hungarian. A detailed analysis is presented of the electromagnetical, mechanical and aerodynamical vibration and noise sources in electrical machines. A summary of the most recent developments in noise pollution is included, as well as the results of the authors' own observations regarding techniques of reducing the noise level of electrical machines and transformers. The vibro-acoustical measuring-technique of machines is discussed generally, both in the steady-state and transient mode of operation. In addition, the noise of transformers and high voltage transmission lines is examined, and the various practical and theoretical methods"

Download or read book A Cultural History of the Modern Age written by Egon Friedell and published by Routledge. This book was released on 2017-07-12 with total page 579 pages. Available in PDF, EPUB and Kindle. Book excerpt: Volume three of A Cultural History of the Modern Age finishes a journey that begins with Descartes in the first volume and ends with Freud and the psychoanalytical movement in the third volume. Friedell describes the contents of these books as a series of performances, starting with the birth of the man of the Modern Age, followed by flowering of this epoch, and concludes with the death of the Modern Age. This huge landscape provides an intertwining of the material and the cultural, the civil and the military, from the high points of creative flowering in Europe to death and emptiness. The themes convey multiple messages: romanticism and liberalism opens the cultural scene, encased in a movement from The Congress of Vienna and its claims of peaceful co-existence to the Franco-German War. The final segment covers the period from Bismarck's generation to World War I. In each instance, the quotidian life of struggle, racial, religious, and social class is seen through the lens of the mighty figures of the period. The works of the period's great figures are shown in the new light of the human search for symbolism, the search for superman, the rise of individualism and decline of history as a source for knowledge. This third volume is painted in dark colors, a foreboding of the world that was to come, of political extremes, and intellectual exaggerations. The author looks forward to a postmodern Europe in which there is a faint glean of light from the other side. What actually appeared was the glare of Nazism and Communism, each claiming the future.
