DC drive technology is efficient, reliable, cost effective, operator friendly and relatively easy to implement. DC drive provides many advantages over AC drives, especially for regenerative and high power applications. DC drives have been widely used in industrial drive applications in order to offer very precise control.
DC drive is basically a DC motor speed control system that supplies the voltage to the motor to operate at desired speed. Earlier, the variable DC voltage for the speed control of an industrial DC motor was generated by a DC generator.
