Understanding Motor Controls,
Stephen L. Herman
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.
experiments start with simple circuits before advancing to more
complicated circuits involving timing relays and auto-transformer
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.
