Zusammenfassung:A universal motor has a brush cage assembly in which a U-shaped clip is located about a wall of a through hole of a bearing bracket for receiving a brush cage . The clip has an outer limb with inwardly and rearwardly directed barbs to grip an outer surface of the wall to prevent removal of the clip and an inner limb with outwardly and forwardly directed barbs which resiliently deform as the cage is inserted to snare the cage should it move in the opposite direction. The clip thus prevents withdrawal of the brush cage and provides a lateral spring force against the cage to reduce cage lateral position tolerance and movement.
