AC Motor Controller Maintenance, Part 1

This course introduces participants to AC motor controllers, which are devices, or groups of devices, that control the operation of alternating current (AC) motors. They can start, stop, or protect a motor; control its speed; and change its direction. By doing so, AC motor controllers make it possible to use motors more effectively in industrial operations. In most industrial facilities, electrical maintenance personnel are responsible for maintaining AC motor controllers and correcting any controller problems that arise.
