Abstract

PURPOSE:To reduce the vibration and noise of a rotary electric machine by forming a plurality of grooves or holes on the back surface of a stator core and burying vibration attenuating members therein. CONSTITUTION:Coils are disposed in the slots 1a of a stator core 1 and fitted with a wedge 3 fixedly, a plurality of grooves 1c with narrow openings are formed on the back surface 1b of the core, and vibration attenuating memebers 4 are buried therein. The members 4 are formed of synthetic rubber, silicone rubber, are inserted into the grooves 1c, and are then secured with an adhesive. In this manner, the stator core 1 is reduced at the vibration value by the operation of the vibration attenuating force of the attenuating members to the back surface 1b of the core 1.
