ABSTRACT:
A motor has a sealed structure, in which a stator core is disposed outside rotors attached to a rotating shaft held by bearings. The motor is equipped with bushes for fixing the bearings, a housing having a through hole from which one end of the rotating shaft protrudes, and pushing spring shims disposed inside the housing for pushing the bush in the longitudinal direction of the rotating shaft. The housing includes a plate portion and a sealing case formed in the shape of a hollow cylinder with a bottom. The bushes have cutout portions formed for positioning the stator core and the rotors in the direction perpendicular to the rotating shaft and for positioning the rotors in the longitudinal direction of the rotating shaft, and the plate portion and the sealing case constituting the housing are sealed by a sealing material.
