Herman/Seiler's UNDERSTANDING MOTOR CONTROLS, 5th Edition, is designed for students with no previous experience in motor controls and introduces basic principles for using components in motor control circuits. Illustrations depict the building of complicated circuits and troubleshooting skills with 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 also 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 concepts, starting with simple circuits and advancing to more complicated topics involving timing relays, programmable devices and auto-transformer starters.
