Why is the Starting Torque of a DC Motor Greater Than That of an AC Motor? DC (direct current) motors generally have higher starting torque compared to AC (alternating current) motors. The starting torque of a motor is crucial for applications where the load initially resists motion, such as in conveyors, crushers, and other heavy-duty machinery.
