Understanding Motor Controls, 4E

Stephen L. Herman

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 reader-friendly experiments start with simple circuits before advancing to more complicated circuits involving timing relays and auto-transformer starters.

Features:

• READER-FRIENDLY LABORATORY EXPERIMENTS ARE NOT BRAND-SPECIFIC FOR MAXIMUM FLEXIBILITY AND ACCESSIBILITY. Because all hands-on lab experiments are not based on a particular brand of relay, timer or other piece of equipment, you can construct and complete the experiments using common motor control components.
• DETAILED EXAMPLES CLARIFY MORE DIFFICULT TOPICS, SUCH AS HOW TO CONVERT A LADDER OR SCHEMATIC DIAGRAM TO A WIRING DIAGRAM. Clear examples and illustrations demonstrate this first step in learning how to connect a working circuit using a schematic diagram. Thoroughly understanding this concept also helps you understand the logic of a circuit.
• EXTREMELY READER-FRIENDLY APPROACH OFFERS EASY-TO-READ EXPLANATIONS WRITTEN IN LANGUAGE READERS CAN UNDERSTAND. The author incorporates many practical illustrations to clarify and explain in a step-by-step sequence how the logic of a circuit works. This proven approach helps ensure the thorough understanding and foundation readers need to advance.
