Book Description
This book describes in detail the construction and working principle of a variety of commercially available hysteresis machines. The last part of the book is devoted to a comprehensive study of an experimental hysteresis machine. The contents of this part derive entirely from the experimental and analytical work carried out by the author during his doctoral research at the University of Aston in the UK. The exhaustive range of tests and measurements, obtained by the use of uniquely devised transducers and techniques—many of these having been evolved for the first time—showcase numerous aspects of a hysteresis machine. These relate mainly to the measured waveforms of radial and peripheral flux density in the airgap and active part of the rotor as influenced by the hysteretic properties of the rotor material.

Book Description
About the Book: It is necessary that a subject like physics is studied, learnt and taught with full comprehension of the various topics of the subject, understanding their numerous facets not only humans but also plants and functions of even bodies all around. This may require not only studying just “theoretical: aspect of physics, but learning these in practice by, for example, conducting relevant experiments where possible. When viewed in this respect, most physics books at school level, including the ones published as “text books”, fail to do full justice to the requirements of learning and teaching physics in class rooms. Many a books are obtained to ‘cover’ the prescribed syllabus under any of the well known streams such as ICSE, CBSE, SSC etc. with too cluttered contents and a horde of solved examples and exercises numbering into dozens at the end of a given chapter which make the students pore over for hours at end with the sole purpose of doing well in the board exams, obtaining marks in nineties, without fully mastering the topics. The present book whilst doing away with many drawbacks as above, has been written by describing all relevant topics of physics at high-school and board level in perspective, relating the topics to their importance in daily life, whilst conforming to various syllabi on physics and enlarging the scope where necessary. The book is structured especially for those students and teachers who have innovative mindset and who would really like to learn physics conceptually, not just to pass board exams with good ‘grades’. The book is enriched with a good number of solved numerical problems with clear step-by-step solution of each and numerous exercises at the end chapter, most question having been derived from the ICSE board exams over the past ten years or so. Contents: 1. Force, Work, Power and Energy 2. Light 3. Sound 4. Electricity and Magnetism 5. Heat 6. Modern Physics

Book Description
This write-up is a near-chronological record of my experiences and memories during my employment at BHEL, Corporate Research and Development Division at Hyderabad from the date of joining, 15 May 1974, to the day of premature retirement on 24 October 1999 – a span of just about a quarter of a century. Whilst describing the (main) events of my 25 years’ stint at BHEL (Bharat Heavy Electricals Limited), comprising the various ups and downs, undoubtably memorable all through, making it a unique experience to have been associated in the capacity of a front-line research engineer with the country’s only ‘electrical’ industry of international repute, manufacturing all kinds of electric-power equipment, once again of worldclass quality, absolutely essential for generation,transmission and distribution of electrical energy and its utilisation by the industry, matching almost 100% demand of the utility – and this beginning within a decade from the time of India’s independence, the narrative brings out the kinds of experience a researcher, or more specifically a research engineer even with a PH D might face in a country like India. I have taken all care to pen down my remembrances as objectively as possible and as I experienced at various stages. However, as can be expected, the memories from nearly 50 years’ past may not keep pace with one’s mind and thought process going back and yet maintain the links. Naturally, there might be instances of ‘slipups’ on my part in terms of dates and details, esp. related to the persons who crossed my path during the decades. For all such ‘omissions’ and ‘errors’ I bear full responsibility with due apologies. For the completion of the record that began nearly two years ago, I acknowledge with sincere thanks all the help from all quarters that came my way.

Book Description
EDDY CURRENTS Understand the theory of eddy currents with this essential reference Eddy currents are electrical current loops produced when a conductor passes through a magnetic field, or is otherwise subject to a change in magnetic field direction. These currents play a significant role in many industrial processes and areas of electrical engineering. Their properties and applications are therefore a subject of significant interest for electrical engineers and other professionals. Eddy Currents: Theory, Modeling and Applications offers a comprehensive reference on eddy currents in theory and practice. It begins with an introduction to the underlying theory of eddy currents, before proceeding to both closed-form and numerical solutions, and finally describing current and future applications. The result is an essential tool for anyone whose work requires an understanding of these ubiquitous currents. Eddy Currents readers will also find: Professional insights from an author team with decades of combined experience in research and industry Detailed treatment of methods including finite difference, finite element, and integral equation techniques Over 100 computer-generated figures to illustrate key points Eddy Currents is a must-have reference for researchers and industry professionals in electrical engineering and related fields.

Book Description
During the past few years the rapid development of computer tech nology has made high power computing facilities more readily accessible to a greater proportion of our industrial and academic community. This development coupled with the recent upsurge in mathematical modelling and computer simulation has led to signif icant developments in electromagnetic field theory and its applic ations to industry. In view of such developments and the present high interest to both academics and industry the theme chosen for the Polymodel 6 Conference held at Newcastle upon Tyne in May 1983 was Industrial Electromagnetics Modelling. To date the North East Polytechnics Mathematical Modelling and Computer Simulation Group has organised five successful Polymodel. conferences each with a different theme. The objectives of the Polymodel group include the promotion of collaborative research between Newcastle, Sunderland and Teesside Polytechnics and industry in the areas of mathematical modelling and computer simulation. The aim of the Polymodel 6 Conference was to call on and use the modelling and computer.simulation expertise of eminent academics and industrialists who are deeply involved in the area of electro magnetics. These proceedings have a twofold purpose in that they contain current analytical and numerical techniques relevant to electromagnetic field problems and useful ideas on the modelling and simulation techniques which are most appropriate. It was also felt important to include implications. of. computer developments (both hardware and software) on such work.

Book Description
This book presents a comprehensive, ordered relationship between malfunctions and symptoms occurring in large turbogenerators. With this book, the operator and/or engineer in a generating station could identify underlying causes of a developing component degradation or a failure quicker, which could potentially save both time and money and reduce the trial-and-error troubleshooting process. Large turbogenerators are the most important source of electricity. They can be found in thousands of power stations in every country. Forced outages, failures and degradation of these very expensive machines have an enormous aggregate cost to society. As such, any tool that can ameliorate loss of production by shaving time from troubleshooting activities, and avoiding unnecessary costs by detecting and promptly responding to component degradation, represents a step forward.
