Abstract

Provided is a washing machine motor capable of efficiently generating torque by improving a winding factor of coils with a relatively simple configuration. The washing machine motor () has an outer rotor (), an inner rotor (), and a stator (). The outer rotor () and the inner rotor () share coils () of the stator (), and a composite current is supplied to the coils () such that the outer rotor () and the inner rotor () are independently driven. The outer rotor () has forty eight outer magnets () arranged such that the N and S poles thereof are continuously and alternately aligned in the circumferential direction thereof. The inner rotor () has forty-two inner magnets () arranged such that the N and S poles thereof are continuously and alternately aligned in the circumferential direction thereof. The stator () has thirty-six I-shaped cores () and the coils ().
