Electric Motors and Drives: Fundamentals, Types and Applications

Electric Motors and Drives 4th edition pdf

Electric Motors and Drives is intended for non-specialist users of electric motors and drives, filling the gap between maths- and theory-based academic textbooks and the more prosaic ‘handbooks’, which provide useful detail but little opportunity for the development of real insight and understanding. The book explores all of the widely-used modern types of motor and drive, including conventional and brushless D.C., induction motors and servo drives, providing readers with the knowledge to select the right technology for a given job.

The third edition includes additional diagrams and worked examples throughout. New topics include digital interfacing and control of drives, direct torque control of induction motors and current-fed operation in DC drives. The material on brushless servomotors has also been expanded.

Austin Hughes’ approach, using a minimum of maths, has established Electric Motors and Drives as a leading guide for electrical engineers and mechanical engineers, and the key to a complex subject for a wider readership, including technicians, managers and students.

  • Acquire knowledge of and understanding of the capabilities and limitations of motors and drives without struggling through unnecessary maths and theory
  • Updated material on the latest and most widely-used modern motors and drives, including brushless servomotors
  • New edition includes additional diagrams and worked examples throughout

Book Review by Calc

Excellent, Practical Technical Book

This is a very good technical book on electric machines and drives, probably one of the best I’ve ever read. It’s truly written in a manner that’s not heavily mathematical, but without losing any technical soundness or being anecdotal. Instead, the author expertly explains the consequence equations have on the practical design of electric machines and drives, the reasons for the design techniques of today’s electric machines and drives, and how to analyze and make assessments for the selection of electric machines and drives.

This new update includes a new chapter for field-oriented control used in VFD’s. I think it’s a worthwhile update to the 3rd edition, but the author sacrifices end of chapter problems for the addition of that chapter. Now, this book has no problems that one can practice, a very unfortunate thing! I don’t know why he did it, if but he felt that the publishing costs would be too high with having to print too many extra pages or if he didn’t want to develop new problems for the new VFD chapter.

I would encourage him at least to bring back the problems for the other chapters in a reprint of this edition! However, the overall book is still excellent and the additional chapter is definitely a must for anyone wanting to understand fully how VFD’s work. Overall, I highly recommend this book for an engineer, technician, or student.

Editorial Reviews


“This book is very readable, up-to-date and should be extremely useful to both users and o.e.m. designers. I unhesitatingly recommend it to any busy engineer who needs to make informed judgments about selecting the right drive system.” –Drives and Controls

“A very useful reference book for anyone wanting a comprehensive understanding of motors and drives … I have not seen another book which covers this wide subject more comprehensively and in such an easy-to-read style.” –Silicon Chip, May 2006

“I would regard this book as a light but broad coverage of many motor and drive concepts that have been around a long time.” –Dennis Feucht, Innovatia.com

“The coverage of drive types and behaviors is thorough and up to date.” –Electrical Apparatus, May 2006
