Book Description
"A first edition of Condition Monitoring of Electrical Machines, written by Tavner and Penman, was published in 1987. The economics of industry have now changed, as a result of the privatisation and deregulation of the energy industry, placing emphasis on the importance of reliable operation of plant, throughout the whole life cycle, regardless of first cost. The availability of advanced electronics and software in powerful instrumentation, computers, and digital signal processors (DSP) has simplified our ability to instrument and analyse machinery. As a result condition monitoring is now being applied to a wider range of systems from fault-tolerant drives of a few hundred watts in the aerospace industry, to machinery of a few hundred megawatts in major capital plant." "In this new book the original authors have been joined by Ran, an expert in power electronics and control, and Sedding, an expert in the monitoring of electrical insulation systems. Together the authors have revised and expanded the earlier book, merging their own experience with that of machine analysts to bring it up to date."--BOOK JACKET.

Book Description
Electric motors are the largest consumer of electric energy and they play a critical role in the growing market for electrification. Due to their simple construction, switched reluctance motors (SRMs) are exceptionally attractive for the industry to respond to the increasing demand for high-efficiency, high-performance, and low-cost electric motors with a more secure supply chain. Switched Reluctance Motor Drives: Fundamentals to Applications is a comprehensive textbook covering the major aspects of switched reluctance motor drives. It provides an overview of the use of electric motors in the industrial, residential, commercial, and transportation sectors. It explains the theory behind the operation of switched reluctance motors and provides models to analyze them. The book extensively concentrates on the fundamentals and applications of SRM design and covers various design details, such as materials, mechanical construction, and controls. Acoustic noise and vibration is the most well-known issue in switched reluctance motors, but this can be reduced significantly through a multidisciplinary approach. These methodologies are explained in two chapters of the book. The first covers the fundamentals of acoustic noise and vibration so readers have the necessary tools to analyze the problems and explains the surface waves, spring-mass models, forcing harmonics, and mode shapes that are utilized in modeling and analyzing acoustic noise and vibration. The second applies these fundamentals to switched reluctance motors and provides examples for determining the sources of any acoustic noise in switched reluctance motors. In the final chapter two SRM designs are presented and proposed as replacements for permanent magnet machines in a residential HVAC application and a hybrid-electric propulsion application. It also shows a high-power and compact converter design for SRM drives. Features: Comprehensive coverage of switched reluctance motor drives from fundamental principles to design, operation, and applications A specific chapter on electric motor usage in industrial, residential, commercial, and transportation applications to address the benefits of switched reluctance machines Two chapters address acoustic noise and vibration in detail Numerous illustrations and practical examples on the design, modeling, and analysis of switched reluctance motor drives Examples of switched reluctance motor and drive design

Book Description
Electrical steels are critical components of magnetic cores used in applications ranging from large rotating machines, including energy generating equipment, and transformers to small instrument transformers and harmonic filters. Presented over two volumes, this comprehensive handbook provides full coverage of the state-of-the-art in electrical steels. Volume 2 describes performance and outlines applications of electrical steels. Topics covered include localised characteristics of electrical steels; practical properties of electrical steels; other electrical steels; prediction of losses in electrical steels; application of electrical steels in transformer cores; applications of electrical steels in rotating electrical machines; non-sinusoidal magnetisation and applications; magnetic building factors in electrical steel cores; use of amorphous ribbon and nano-materials in transformer cores; electrical machine core vibration and noise; approaches to predictions and measurements of flux density and loss distributions in electrical machine cores; the application of international standards to magnetic alloys and steels; electrical steels and renewable energy systems; environmental impact of electrical steels; and typical performance data of commercial electrical steels.

Book Description
In this book, the authors have attempted to present many aspects of electrical steels technology. These range from how their magnetic properties are determined by fundamental principles of magnetism and metallurgical features to their influence on the performance of rotating electrical machines and transformers. This should cater for readers, who might be involved in material production, to appreciate how steels have to respond to large differences of localised magnetisation conditions in electrical machine cores. Equally, it should satisfy readers involved in electrical machine manufacture, or operation, who need to understand magnetic factors which should be taken into account in the choice and use of the materials. Although the book only touches on commercial issues of the production and use of electrical steels, it should be noted that the industry is in a state of flux. For political or financial reasons, over the last few years the number of producers has dropped significantly and others are merging or restructuring. However, the demand for high quality electrical steel is set to continue to increase in the future, with increased emphasis being placed on the best grades.
