Abstract
A driving system of a driving motor is proposed. The system includes: a stator having slots at which coils are wound; a first inverter connected to first ends of the coils of the stator; a second inverter connected to second ends of the coils of the stator; and a stage switch circuit configured to control an electrical connection between the second ends of the coils of the stator and the second inverter. In particular, the coils include a first coil set connected to an output terminal of the first inverter, and a second coil set connected to an input terminal of the second inverter. Currents having the same phase or currents having different AC phases are applied to the first coil set and the second coil set wound at the slots by controlling on and off of the stage switch circuit.
