International ClassH02K 013/00AbstractA 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.Field of SearchBrush holders or riggingBrush engagements or guides Brushes Impregnated or coated Vibration or noise suppression Housings, windows or covers Supports Connectors, terminals or lead-ins Slidable brush Axial spring With assembling, metal casting or machining feature Dynamoelectric machine Commutator or slip ring assembly Having means to mount pump and motor in working position | |
