Designed for students with no previous experience in motor controls, UNDERSTANDING MOTOR CONTROLS, 3e introduces basic principles and progresses from learning about common motor control components to how they are used in motor control circuits. The new edition is packed with illustrations concerning troubleshooting circuits and offers thorough explanations of the basic types of meters and test equipment needed for troubleshooting control circuits. Written in accord with the National Electrical Code, Chapter 37 on the installation of motors has been completely updated and now offers an even stronger illustration of how overload heater sizes are actually selected. Using actual motor control components, hands-on laboratory experiments enable students to put what they learn into practice. These student-friendly experiments start with very simple circuits and progress to more complicated circuits involving the use of timing relays and an auto-transformer starter.
"The sections on the various controls are good for the most part." "There is a wonderful number of schematics! My students are technically minded and that will help them picture what is really going on inside."
— Keith Dinwiddie, Ozarks Community College
