Electric
Motor Control, 9E
Ninth Edition
Stephen L. Herman
With a highly
practical approach, ELECTRIC MOTOR CONTROL, 9E provides a
useful and effective tool for anyone who will install, monitor,
and/or maintain motor controls.
The book begins by introducing the simplest of
equipment and then builds upon this knowledge, step-by-step,
enabling readers to learn how to draw and interpret motor control
schematic diagrams.
Subsequent units provide useful information on
motor control components and how they are connected to form complete
control circuits.
Features:
- Final unit 60 on troubleshooting techniques provides real-life
tools for readers.
- Updated content includes coverage of Mercury bulb float
switches.
- Chapter 3 Magnetic Line Voltage Starters has been heavily
revised.
- Over 30 updated photos and line illustrations.
- VISUAL AIDES: Includes updated artwork and schematic diagrams.
- INSTRUCTIONS: Step-by-step instructions are given on how to use
the voltmeter, ammeter, and ohmmeter when troubleshooting a control
circuit.
- UNITS: Short, self-contained, 4-10 page units are a key
trademark feature of this book so that content can be easily matched
up with teacher and learner needs.
