CPC classification number: H02K9/06

Abstract: A motor includes a rotor and a stator. The rotor comprises a rotating shaft and an impeller. The impeller couples with the rotating shaft and has a hub. The hub has an outer surface, an inner surface, a plurality of first through holes and a plurality of second through holes. The first through holes are disposed nearer the rotating shaft than the second through holes. The stator comprises a silicon steel sheet and a bearing assembly. The silicon steel sheet has an annular portion and a plurality of protruding portions. The rotating shaft couples with the bearing assembly and penetrates within an inner hole of the annular portion. Each protruding portion is extended outward from the annular portion and has an extending length. The distance between the first through hole and the nearest second through hole is in a range of 0.3 to 1.2 times of the extending length.
