Abstract: The washing machine of the present disclosure includes an improved pulley for reducing the noise generated in the pulley. When the shaft is inserted into the shaft insertion hole, at least a part of the shaft is closely contacted with the shaft insertion hole to minimize the tolerance between the shaft and the shaft insertion hole, and the rotation shaft of the pulley and the center axis of the shafts may be made to coincide with each other, so that the noise generated by the rotation of the pulley can be effectively reduced. In addition, the spoke of the pulley includes the curved portion, thereby reducing the friction with the air and effectively reducing noise due to friction with air.

Abstract: A drive motor includes: a double stator including a stator core, a first coil wound on one side of the stator core, and a second coil wound around the other side of the stator core; and a double rotor including a rotor support connected to a drum via a rotating shaft, an outer rotor fixed to the rotor support and arranged with a gap on the outer surface of the stator, and an inner rotor fixed to the rotor support and arranged with a gap on the inner surface of the stator. The drive motor drives to rotate two rotors of the double rotor by applying a drive power to the first and second coils at wash and rinsing strokes, and drives to rotate only one rotor of the double rotor by applying the drive power to only one of the first and second coils at a dehydration stroke.
