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.

Abstract: A laundry drying machine includes: a cabinet, a drum rotatably disposed in the cabinet and configured to accommodate a target object, an electric field generator spaced apart from the drum and configured to, based on power being applied to the electric field generator, generate an electric field, and an exhaust duct configured to discharge air inside the drum. The electric field generator includes: (i) an anode electrode spaced apart from the drum, fixed to the cabinet, and configured to apply the electric field to the target object, (ii) a power supply unit configured to supply the power to the anode electrode, and (iii) a matcher configured to match a source impedance of the power and an impedance of a load side. The drum is configured to, based on a reflectivity of the electric field exceeding a predetermined ratio, reduce a rotation speed.
