This book discusses the current status of the solid-state AC motor controls. It treats most technical phenomena in the empirical sense, with emphasis on input-output characteristics of solid-state controls, oriented at all times to their effect on the performance of the AC motor.

Gain the knowledge that industrial electricians in the field need in order to be successful! The subject of motor controls is one of the major areas of concern for industrial electricians, and this book prepares readers for work in the industry. A "real-world" systems approach is applied to all aspects of motor control, including basic control circuits, sensing devices, solid-state controls, variable speed drives, programmable logic controllers (PLCs), and more. "Must know" applications, procedures, and operations are stressed throughout. Coverage concludes with a series of practical laboratory exercises to help provide an excellent knowledge base of important installation, testing, and troubleshooting procedures.
