Abstract

See full text

A dual rotor-type motor includes a stator having a coil wound therearound, an outer rotor, and an inner rotor. The stator includes inner teeth facing the inner rotor, and outer teeth facing the outer rotor, and the inner teeth are misaligned in a rotating direction by as much as an angle with respect to the outer teeth, which may enable the reduction of a torque ripple to a satisfying level, even without having to change the design of the stator structure into a complicated form.
