Abstract
An electric motor includes an armature structurehaving a shaft, a lamination stackcoupled with the shaft, a commutatorcoupled with the shaft, and windingscarried by the lamination stack and connected to the commutator. Brushesengage the commutator to deliver electric current to the windings. The motor includes a frame structureand permanent magnetscarried by the frame structure. At least one assembly is provided including a sleeve bearing, an elastomer structurecoupled with the sleeve bearing, and a retainer. The sleeve bearing is operatively associated with an end of the shaft to support the shaft for rotation. The elastomer structure is clamped between the frame structure and the retainer, with the retainer being engaged with a portion of the frame structure to maintain clamping on the elastomer structure. The assembly is constructed and arranged to reduce transmission of noise from the sleeve bearing to the frame structure, and to control endplay of the armature structure by controlling compression of the elastomer structure due to clamping by the retainer.
