The DC drive has been made to convert the Alternating Current (AC) into Direct Current (DC). This is accessible with a higher motor speed and ensures smooth running of motor at correct speed. This is suited for AC applications and is demanded for DC applications. DC drive is demanded for servo motor applications. It is needed for the running if cranes, lifts, pump, fans, overhead cranes, feeders, mixers, conveyors, dispensers and others. Advantages include easy installation, good speed control, simple starting torque, quick starting, simple acceleration, great reversing and accurate step-less speed with constant rotation.
