Description:

Install, troubleshoot, and test electrical motors like the pros! UNDERSTANDING MOTOR CONTROLS, 2ND Edition uses a real-world systems approach to learning motor control devices. Starting with basic control circuits and components, thisbook covers all must-know applications and procedures to ensure your success in the more complex topics. From safety and development to operations and problem solving, UNDERSTANDING MOTOR CONTROLS, 2ND Edition prepares you for a career as an industrial electrician with a solid foundation in basic control circuits, sensing devices, solid-state controls, variable speed drives, programmable logic controllers (PLCs), and more.

Product Benefits:

  • Code references had been updated throughout to reflect the 2011 NEC, preparing industrial electricians with the most up-to-date information available.
  • Includes extended information on Control Transformers, Motor Nameplate Data, Hall Effect Sensors, and On-delay Timers.
  • Enhanced with information concerning the operation of single-phase and three-phase motors, as well as more discussions on troubleshooting motors.
  • Drawings and charts throughout the book have been updated and revised to depict the real world responsibilities of modern industrial electricians.
  • Written for instructors who require streamlined, focused content, delivering essential material in a smaller, easy-to-understand format.
  • Future Industrial Electricians will learn the language of the trade with the book's standard NEMA symbols and key 2011 National Electrical CodeĀ® information throughout the book.
  • Beginning with clear explanations of the logic behind control systems, the book moves from very simple control circuits to more advanced circuits for organized, common-sense learning.
  • Covers the basic control components such as limit switches, flow switches, and pressure switches, as well as all of the key areas of knowledge for industry professionals.
  • Covers the basic control components such as limit switches, flow switches, and pressure switches, as well as all of the key areas of knowledge for industry professionals.
