Motor controls can ideally be identified as a group of devices that govern the performance of an electric motor in a predefined manner. Motor controls are also known as motor controllers. They have several essential functions which include: automatically or manually starting as well as stopping the operation of an electric motor, setting forward or reversing the course of rotation, selecting and regulating the speed of rotation, controlling or regulating the torque, as well as protecting the motor against several degrees of electrical overloads and faults.
