1. A winding pattern of a driving motor in a driving system in which a first inverter and a second inverter are connected to the driving motor, a first end of a stator winding through which 3-phase current flows is connected to an output line of the first inverter, and a second end of the stator winding is connected to an output line of the second inverter, the winding pattern comprising:
coils, which are wound in slots defined in the stator of the driving motor and to which 3-phase current is applied;
coils, which are wound on an innermost side and an outermost side defined by a direction toward a rotating shaft of the driving motor in each of all the slots defined in the stator and which are energized by different AC phases; and
coils, which are disposed between a first coil located on the outermost side and a second coil located on the innermost side and which are energized by the same AC phases as the AC phases of the first coil and the second coil,
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.
