A dual rotor-type motor, according to one embodiment of the present invention, comprises: a stator having a coil wound therearound; an outer rotor; and an inner rotor, wherein the stator comprises inner teeth facing the inner rotor, and outer teeth facing the outer rotor, wherein the inner teeth are misaligned in a rotating direction by as much as an angle configured with respect to the outer teeth, and thus the present invention 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.
