At last: field-tested solutions to your electric drive problems. Packed with proven industrial applications and plenty of worked examples, Vedam Subrahmanyam's Electric Drives gives you everything you need to identify and solve virtually any electric drive problems you're likely to encounter. It's the first authoritiative, hands-on guide to both conventional and static converter-based drives. You'll find critical information on closed-loop control and the dynamics of drives, as well as their common technical problems--plus: details on thrister power converters and the drives that employ them; the control aspects of electrical drives; controller design for optimal drive behavior; applications of microporcessors in electric drives; extensive comparisons of various drives; industrial applications--from textile mills to coal mines; dozens of sample problems that help you master concepts; and more.

Contents
Characteristics of Electric Motors. Dynamics of Electric Drives. Converters for Feeding Electric Motors. Control of Electric Motors. Rating and Heating of Motors. Control Techniques for Electrical Drives. Drives for Specific Applications. Microprocessors and Control of Electric Drives.

From the Back Cover
All the details you need to get the best performance from any electric drive Electric Drives: Concepts and Applications. In this complete guide, an international expert taps the latest developments in the field to show you how to get optimal performance from any electric drive. Electric Drives shows you exactly how to: get the fastest dynamic response, the most accurate speed control, and more with thyristor power converters; design controllers to improve the static and dynamic behavior of the drive; maximize the use of microprocessors in electric drives; improve the dynamics of conventional systems with closed-loop systems; make the right choice with an extensive comparative analysis that details the common technical problems of a wide variety of drives. Plus, this ideal reference reviews elementary theory of electrical machines and conventional speed control methods (without deep mathematical analysis), and presents detailed discussions of closed-loop control and the dynamics of drives.

Reviews:

I found this book to be superbly written. The author covers all aspects of thyrister controlled converters and inverters. He has tremendous knowledge of the subjet.

After reading this book, I've come to completely understand particular characteristics of electric motors. Some examples are: the four quadrant operation of motors; dynamic and regenerative braking, and the difference between the two; and voltage control of motors.

Although I've worked with wound rotor motors I've never seen one with a "slip power energy recovery scheme". This book details such schemes which is very interesting.

The cycloconverter is shown throughout this book which I find extremely interesting. Siemens uses the cycloconverter in their marine electric propulsion systems. I now know more about the cycloconverter.

This is one outstanding book.
