PROBLEM TO BE SOLVED: To suppress the tremor of the tip of a stator tooth. SOLUTION: A motor, which is equipped with a stator having slots 13 among teeth 12 and a rotor, is provided with a wedge 20 which is made of insulating material such that it closes the opening on the inner perimetrical side of the slot 13. Since the wedge made of insulating material is provided to close the opening on the inner perimetrical side of the slot, it can reduce accoustic tremor by controlling the tremor of the tooth tip. Since it is simple of form, it can reduce the cost in manufacture. COPYRIGHT: (C)2009,JPO&INPIT
