<p>A washing machine motor of the present invention comprises: an outer rotor connected by a washing tub through an outer shaft; an inner rotor connected by a pulsator through an inner shaft; a stator arranged in an air gap between the inner rotor and the outer rotor and independently driving the inner rotor and the outer rotor; and a planetary gear unit provided at the inner shaft so as to increase torque by reducing speed, wherein the outer shaft rotates at the same speed as the inner rotor, and the inner shaft is decelerated compared with the rotational speed of the inner rotor so as to increase the torque. The washing machine motor can form various washing water currents by enabling an output of the inner rotor having a small generated torque to drive the pulsator through the planetary gear unit and enabling an output of the outer rotor having a large generated torque to drive the pulsator and the washing tub in the reverse direction by driving the washing tub through the planetary gear unit without changing speed, and can implement a large-capacity washing machine.</p> |
