<p>An electric motor assembly capable of withstanding heavy side loading includes a motor housing having a shell with first and second end shields including bearing supports having bearings therein. The first end shield further includes a flange for connecting a compressor to the motor. A rotor is rotatably mounte d in the housing and supported by the bearings. A stiffening collar, positioned betwe en a rotor core and the first end shield, surrounds a portion of a rotor shaft an d provides support for the shaft against deflection due to heavy side loading. A centrifugal mechanism and a spacer are positioned on the rotor assembly outboard of the motor housing. The motor assembly also includes a cover attached to the second end shield. The cover holds a start capacitor, a run capacitor and a centrifugal switch and further includes snaps for mounting the centrifugal switch to the cover. An overload and an overload bracket extend, at least partially, through an opening in the secon d end shield. The overload bracket includes snaps that engage the second end shiel d and maintain the bracket and overload in position. A load washer having a plurality of snaps engages the second end shield and maintains the load washer in positio n on the second end shield.</p> |
