Abstract:
A dual shaft integrated motor includes an inner rotor and an outer rotor that are independently rotatable and rotate in an identical pivotal direction. The inner rotor, an inner stator, an outer stator, and the outer rotor are sequentially arranged from a pivot in a radial direction. The inner stator and the outer stator interpose a non-magnetic body therebetween, the non-magnetic body being provided at a position contiguous with the inner stator and the outer stator along a circumferential direction centering on the pivot.
