A motor of washing machine according to the present invention comprises: an outer rotor connected by a washing machine tub through an outer shaft; an inner rotor connected by a pulsator through an inner shaft; a stator disposed between the inner rotor and the outer rotor placing a gap and operates the inner rotor and the outer rotor independently; and a planetary gear installed to the inner shaft to reduce velocity and increase torque, wherein the outer shaft is rotated at same speed as the outer rotor, and the inner shaft is decelerated compared with rotation speed of the inner rotor in order to increase torque. In such a motor of washing machine output of the inner rotor with a small torque drives a pulsator through a planetary gear system, whereas output of the inner rotor with a great torque generate drives a washing machine tub through a planetary gear system, thereby reverse driving of the pulsator and the washing machine tub is enabled, so a bulk washing machine can be provided. |
