Herman/Seiler's UNDERSTANDING MOTOR CONTROLS, Cengage International Edition, is designed for students with no previous motor control experience. It introduces basic principles and common motor control components to build simple control circuits. Illustrations depict troubleshooting circuits using basic types of meters and test equipment. While the use of modern equipment is highlighted throughout the book, legacy types of timers and other motor control devices are included for reference. Updates include the most recent edition of the National Electrical Code®, clearly illustrating how to select overloads and protect the control circuitry. Motor control components and hands-on laboratory experiments enable students to practice and apply the concepts, starting with simple circuits and advancing to more complicated circuits involving timing relays, electronic control devices and auto-transformer starters.
