Abstract: A structured product family of dynamoelectric machines for use in a plurality of applications has a frame with a closed end, and a set of permanent magnets is adhesively secured within the frame. An armature disposed in the frame for interaction with the permanent magnets includes a shaft, a core having a set of winding receiving slots therein, and a commutator. During manufacturing and assembly, stress on the motor shaft and commutator is minimized. A brush plate is associated with the frame for locating a set of brushes relative to the commutator, and an end shield is secured to the frame opposite its closed end. At least one freely aligning bearing assembly disposed in the end shield for freely aligning the shaft and including a bearing and a retainer having predetermined conditions preset with the retainer being adhesively secured to the end shield. A bracket is adhesively secured to the frame for connecting the dynamoelectric machine in anyone of the applications; and a novel brush assembly is provided.

Abstract: A lubricant slinger mechanism for preventing the loss of oil or other lubricant which is pumped between the rotor shaft and bearing in an electric motor or other dynamoelectric machine. The slinger is mounted to the rotor shaft and mounted adjacent the end of the bearing out of which oil flow at it is pumped along the shaft from the reservoir. The slinger initially throws the oil radially outward against an inner oil well cover, and the provision of an impeller, such as a spiral vane on the outer peripheral surface of the slinger, imparts an axial component of velocity to the lubricant which impels it rearwardly toward the reservoir and prevents the migration of oil out of the forward end of the oil cover through which the rotor shaft extends. The slinger, in one form thereof, includes an annular cup portion which overhangs the end of the bearing so that lubricant is thrown off the slinger at a point rearwardly of the end of the bearing.
