This book has been written for a course of study that will introduce the reader to a broad range of motor types and control systems. It provides an overview of electric motor operation, selection, installation, control and maintenance. Every effort has been made in this first edition text to present the most up-to-date information which reflects the current needs of the industry.
The broad based approach taken makes this text viable for a variety of motors and control systems courses. Content is suitable for colleges, technical institutions, vocational/technical schools as well as apprenticeship and journeymen training. Electrical apprentices and journeymen will find this book to be invaluable due to Electrical Code references applicable to the installation of new control systems and motors, as well as information on maintenance and troubleshooting techniques. Personnel involved in the motor maintenance and repair will find this book to be a useful reference text.
The text is comprehensive! It includes coverage of how motors operate in conjunction with their associated control circuitry. Both older and newer motor technologies are examined. Topics covered range from motor types and controls to installing and maintaining conventional controllers, electronic motor drives and programmable logic controllers.
Also Available! Activities Manual for Electric Motors and Control Systems

Each chapter constitutes a complete and independent unit of study. All chapters are divided into parts designed to serve as individual lessons. Instructors can easily pick and choose chapters or parts of chapters that meet their particular curriculum needs.
When the operation of a circuit is called for a bulleted list is used to summarize its operation. They are used in place of paragraphs and especially helpful when explaining the sequenced steps of a motor control operation.
When the operation of a piece of equipment is illustrated by means of a diagram a photo of the device is included. This feature is designed increase the level of recognition of devices associated motor and control systems.
Troubleshooting is an important element of any Motors and Controls course. The chapter troubleshooting scenarios are designed to help students with the aid of the instructor to develop a systematic approach to troubleshooting.
These open-ended questions are designed to give students an opportunity to reflect upon the material covered in the chapter. In most cases they allow for a wide-range of responses and provide an opportunity for the student to share more than just facts.
