Preface:
The amount of knowledge an electrician must possess to be able to install and troubleshoot control systems in today’s industry has increased dramatically in recent years. A continuous influx of im proved control components allows engineers and electricians to design and install even more sophisti cated and complex control systems. Industrial Motor Control presents the solid-state devices common in an industrial environment. This is intended to help the student understand how many of the con trol components operate, such as solid-state relays, rectifiers, SCR drives for direct current motors, variable frequency drives for alternating current motors, and the inputs and outputs of programmab lecontrollers. Although most electricians do not troubleshoot circuits on a component level, a basic knowledge of how these electronic devices operate is necessary in understanding how various control components perform their functions.
