Description: Gain the knowledge that industrial electricians in the field need in order to be successful! The subject of motor controls is one of the major areas of concern for industrial electricians, and this book prepares readers for work in the industry. A "real-world" systems approach is applied to all aspects of motor control, including basic control circuits, sensing devices, solid-state controls, variable speed drives, programmable logic controllers (PLCs), and more. "Must know" applications, procedures, and operations are stressed throughout. Coverage concludes with a series of practical laboratory exercises to help provide an excellent knowledge base of important installation, testing, and troubleshooting procedures. Product Benefits: - teaches readers how to recognize standard NEMA symbols and familiarizes them with important information on motor installation that is in accordance with the 2005 National Electrical Code®
- clear explanations of the logic of control systems begins with very simple control circuits and progresses to more advanced circuits for organized learning
- covers the basic control components such as limit switches, flow switches, and pressure switches, that readers are likely to encounter throughout their work in the industry
- introduces the basics of programmable logic controllers and how they operate, as well as how a standard relay control system can be converted for loading into a PLC
