A distal end of each of the teeth forms a tooth tip, with a slot opening formed between each two adjacent tooth tips. The rotor includes a permanent magnet forming a plurality of magnetic poles. The stator and the rotor define an air gap therebetween. A circumferential width of the slot opening is equal to or less than two times of a radial width of the air gap.
