Motor driver is basically a device that converts constant voltage into variable voltage. This drivers make it possible to operate electric motors and control the speed and torque of the motor.
Motor driver sets the operating parameters of the motor by converting the constant voltage from the main AC power supply into a variable voltage. These devices are available designed with different features. Different control strategies can be used according to the motor’s characteristics and intended use. The most common types of drivers include AC motor or DC drivers and servo type drivers.
