Description
Using a real-world systems approach to learning motor control devices, UNDERSTANDING MOTOR CONTROLS, 3rd Edition teaches you to install, troubleshoot, and test electrical motors like the pros! Starting with basic control circuits and components, this book 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 prepares you for a career as an industrial electrician with a strong foundation in basic control circuits, sensing devices, solid-state controls, variable speed drives, programmable logic controllers (PLCs), and more. In addition, hands-on lab experiments give you practice putting what you learn into real-world practice.
Benefits
  • 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.
  • 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.
