Updated with the latest technology, machines, and controls in the industry, ELECTRIC MOTOR CONTROL, 10E delivers comprehensive coverage and practical insight for anyone who will install, monitor, and/or maintain motor controls. Extremely reader friendly, the book begins by introducing the simplest of equipment and then helps you build on your knowledge as you learn step by step how to draw and interpret motor control schematic diagrams. Subsequent units offer detailed coverage of motor control components and how they are connected to form complete control circuits. The book ends with troubleshooting techniques that provide real-world practice.
  • Completely up to date and more comprehensive than ever, the new Tenth Edition includes expanded coverage of push-buttons and selector switches, relays, contactors pressure switches, temperature switches, temperature sensing devices, hand-off-auto switches, and much more.
  • The new edition uses a detailed schematic diagram to more clearly illustrate how a circuit is connected.
  • Updated schematics provide thorough explanations of part winding starting.
  • Coverage of direct current motors has been expanded.
  • Additional discussions of control transformers are now included.
  • Dynamic braking for AC squirrel cage motors is explained in detail.
  • In addition, ELECTRIC MOTOR CONTROL now includes an instructor companion website that provides a PDF of the IML, PowerPoint slides, an image gallery, and a test bank-all at your fingertips.
  • Succinct, self-contained units remain a signature feature of this popular text. At about 4-10 pages each, the units are easily matched up with teacher and learner needs-offering instructors optimum flexibility to meet your students' unique needs.
  • A wealth of up-to-date photos, line illustrations, artwork, and schematic diagrams vividly illustrate chapter concepts.
  • Extremely reader friendly, the text provides step-by-step instructions on how to use the voltmeter, ammeter, and ohmmeter when troubleshooting a control circuit.
  • Updated content includes coverage of mercury bulb float switches.
  • The text is popular for its heavy industrial orientation and focus on electromechanical controls.
  • After delivering comprehensive coverage throughout, ELECTRIC MOTOR CONTROL, 10e concludes with unit 60: Troubleshooting Techniques, which effectively equips readers with real-life tools for real-world practice.
