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.

    Glossary.

    • Providing flexibility and accessibility, lab experiments are not based on a particular brand relay, timer, or other piece of equipment but can be constructed from common motor control components.
    • Detailed examples show students how to convert a ladder or schematic diagram to a wiring diagram, which is the first step in learning how to connect a working circuit using a schematic diagram. This concept also helps students understand the logic of a circuit, which aids in learning troubleshooting techniques.
    • Extremely student friendly, the text is written in an easy to read and understand level. Many practical illustrations explain in a step-by-step sequence how the logic of a circuit works -- ensuring thorough student understanding.
    • Packed with new photographs and updated graphics that bring chapter concepts to life through detailed illustrations.
    • Includes expanded coverage of pressure switches.
    • Reflecting the latest developments from the field, the Third Edition features extended information on IEC and NEMA symbols.
    • Increased coverage of troubleshooting equips students with the tools and knowledge to deal with issues they will face in real-world practice.
    • Providing tools to help instructors maximize course success, the Instructor Resource site includes PowerPoint presentations, test banks, and an image gallery.
  • "Location and community needs dictate particular emphasis on certain areas of the Motor Control Industry; UNDERSTANDING MOTOR CONTROLS is a well-balanced text that should meet the needs of any area." "The questions are presented in a way that requires thought yet at the same time are not as though their content is out of bounds with the information within the particular unit."
