The 4th Edition of “Electric Motors and Drives: Fundamentals, Types and Applications” by Austin Hughes and Bill Drury is a book that can help expanding our knowledge about electric motors. What is interesting to note is that this latest edition is co-authored.
The first three editions of the book were written by Austin Hughes - a teacher and researcher at the University of Leeds, UK. In this edition Bill Drury was brought in with his knowledge and expertise in more modern and advanced motor technology – he was the Executive Vice-President of Technology at Emerson – Control Techniques, as well as a Visiting Professor at the universities of Bristol and Newcastle, UK.

Another characteristic of the book is that it targets a broad audience of specialists in different fields that have something to do with motors, but are not exclusively focused on them.
That is why the authors’ philosophy is to present the material in a balanced way – deeper analysis of the subject without the purely academic analytical approach of a textbook.

The more than 400 pages material of the book is divided in eleven chapters. The first introduces the basics of electric motors, with the second covering the fundamentals of power electronic converters for motor drives.
The following chapters are focused on specific types of motors. Chapters three and four describe conventional DC motors and DC motor drives.
The next four chapters cover different aspects of induction motors. Chapter 5 introduces their rotating field, slip and torque. Chapter 6 then describes the operation of induction motors with 50 and 60 Hz supply, followed by analysis of their variable frequency operation in Chapter 7.

Finally, the next chapter covers inverter-fed induction motors.
Chapter 9 is dedicated to synchronous and brushless permanent magnet machines and drives, while the following chapter describes stepping and switched-reluctance motors.
After covering in sufficient detail the different types of motors and their operation, the last chapter of the book provides some guidelines for the selection of motors and drives.

Two appendices at the end introduce closed-loop control and the equivalent circuits of electric motors.
In conclusion, the book can be a very helpful tool of all PAC specialists that are interested in expanding their knowledge of electric motors and their impact on PAC systems in this rapidly changing world.  

The last chapter of the book discusses the future of the Smart Grid from the point of view of expectations and challenges, as well as the directions for its future development.
The wide range of topics covered in the book together with the analysis of different technologies, their applications and the related international standards make it a valuable resource that can be used by many specialists in the protection, automation and control field to get a deeper understanding of the challenges and solutions that our industry is facing.
