ABSTRACT:
A dynamoelectric machine has a rotor affixed to a shaft which is journaled at each end by a bearing assembly. These elements preferably are assembled in a housing. A simplified system for controlling end movement or end play of the shaft during transport of the motor and motor start-up and coast-down eliminates the need for end play washers normally associated with motor construction. The system includes a stop (3) molded into an endshield of the motor so as to be integrally formed in one end wall of the housing, while a spacer (7), which can bear against the bearing at the other end of the shaft restrains end play in the opposite direction.
