Abstract:
A washing machine includes a driving motor having a stator, an outer rotor connected to the inner shaft and rotatable outside the stator, and an inner rotor connected to the outer shaft and rotatable inside the stator. Stator slots, which are fixedly-installed as a coil are wound on stator teeth. The outer rotor and the inner rotor include rotor teeth, a permanent magnet and a bushing, spaced from an inner circumference of the stator and rotates centering around a rotor shaft by magnetic force. The rotor teeth includes a teeth extension portion extending from a side end of an outer circumference of the rotor teeth in a circumferential direction, a cut recess cut in a concaved manner from the outer circumference of the rotor teeth toward the center of the rotor shaft, and an insertion recess cut in a concaved manner in a radial direction from an inner circumference of the rotor teeth.
