Abstract
Provided is a washing machine motor including: an inner rotor connected with an outer shaft; an outer rotor connected with an inner shaft; and a stator disposed with an air gap between the inner rotor and the outer rotor, wherein the outer shaft is rotated at the same speed as that of the inner rotor, and the rotational speed of the inner shaft is decelerated compared to that of the outer rotor so as to increase a torque, and wherein a first bearing and a second bearing are disposed on an outer surface of the outer shaft in order to rotatably support the outer shaft, and the first bearing is mounted in the stator. The washing machine motor includes a planetary gear set that decelerates the rotational speed of the inner shafts and increases the torque, to thereby implement a large-capacity washing machine.
