Classification: CPC H | IPC H

Claim 8:
9. A motor driving system comprising:
a driving motor including a stator defining therein slots in which coils to which 3-phase current is applied are wound;
a first inverter connected to a first end of a winding of the stator through which the 3-phase current flows;
a second inverter connected to a second end of the winding of the stator through which the 3-phase current flows; and
a switch configured to control an electric connection between the second end of the winding of the stator and the second inverter,
wherein coils, which are energized by different AC phases on an innermost side and an outermost side defined by a direction toward a rotating shaft of the driving motor, are wound on each of all the slots defined in the stator,
wherein coils, which are energized by the same AC phases as the AC phases of a first coil and a second coil, are disposed between the first coil located on the outermost side and the second coil located on the innermost side,
wherein the coils disposed in odd positions based on the first coil disposed on the outermost side of each of the slots are energized by the same AC phases, and
wherein the coils disposed in even positions based on the first coil disposed on the outermost side of each of the slots are energized by the same AC phases.
