The author's earlier book Electric Motors (Workshop Practice Series No. 16) described the basic principles of operation and methods of application of the wide range of motor types likely to be encountered in small scale engineering. This book provides additional information about popular workshop applications for motors. Detailed advice is given on how to identify and make good use of discarded and surplus motors from both domestic and industrial sources and also how to operate three phase motors from single phase supplies. Examples are given of actual workshop applications and conversions, and on battery supplies for the use of motors in mobile projects.
