ABSTRACT:
The present invention relates to motors, and more particularly, to a double rotor type motor applicable to a washing machine or the like. The double rotor type motor includes an outer rotor having first base, and a first extension extended from a circumference of the first base substantially perpendicular thereto, the first extension having outer magnets mounted on an inside circumferential surface, an inner rotor having a second base mounted on an upper surface of the first base concentric to the first base, and a second extension extended from a circumference of the second base so as to be opposite to the first extension with a predetermined gap toward an inner side of the first extension, the second extension having inner magnets mounted on an outside circumferential surface, and a bushing at a center of the first base and the second base, for transmission of rotation force both from the outer rotor and the inner rotor to a rotating shaft.
