Understanding Motor Controls/Изучение механизмов управления двигателем

Книга на английском языке
Designed for students with no previous experience in motor controls, Herman's UNDERSTANDING MOTOR CONTROLS, 4E introduces basic principles and guides readers from learning about common motor control components to understanding how to use components in motor control circuits. Numerous up-to-date illustrations depict troubleshooting circuits while thorough explanations detail basic types of meters and test equipment to troubleshoot control circuits. An updated chapter on installing motors corresponds with the National Electrical Code and clearly illustrates how to select overload heater sizes. Using actual motor control components, hands-on laboratory experiments enable students to practice the concepts they've learned. These student-friendly experiments start with simple circuits before advancing to more complicated circuits involving timing relays and auto-transformer starters.
