This book deals with principles and characteristics of the wide range of motor types likely to be useful in small engineering workshop applications. It also covers matters such as speed control, electric braking, generators, installation and safety aspects – everything, in fact, of practical value to the small workshop user.

In the years since the publication of the first edition, the book has become a well-established reference source for users to dip into when more information is needed on how motors behave both in standard usage and also in less common applications. In this time a lot has happened in the field of motor design.

This second edition now contains updated information covering both these later developments in motor types and their control systems. A major section is devoted to the characteristics and installation of Variable Frequency Drive units (VFDs). It also covers the operating differences between North American and European power systems.

The author, Jim Cox, was Chief Engineer of a well-known electronics company and spent his working life closely involved with electronic and electro-mechanical equipment. He has been a keen model engineer for many years and is well aware of both the needs of small engineering workshops and the capability of their owners. He is also known as a familiar contributor to Internet News Groups under his ‘pentagrid’ signature.

Contents: Safety; Basics; Induction Motors; Variable Frequency Drives; 3 Phase Operation; Commutator Motors; Stepper Motors; Speed Control and Electric Braking; Generators; Installation and Protection; Identifying and Using Scrap Motors; Test Equipment.
