ABSTRACT:
A rotor assembly for an electric machine includes a rotatable shaft, a rotor core coupled to the shaft for common rotation, and an impeller coupled to the shaft for common rotation. A bearing is coupled to the shaft generally between the rotor core and the impeller. The bearing can include an outer race sized smaller than an opening defined by the machine housing. The bearing can include steel rolling elements such as steel balls or generally cylindrical steel rollers. An adaptor sleeve can be disposed generally around the outer race. The adaptor sleeve can be disposed within the opening defined by the housing for securing the adaptor sleeve and the bearing within the opening defined by the housing.
