Patent ID: 6998746

Claim:
An electric motor comprising: an armature structure including: a shaft, a lamination stack coupled with the shaft, a commutator coupled with the shaft, and windings carried by the lamination stack and connected to the commutator, brushes engaging the commutator to deliver electric current to the windings, a frame structure, permanent magnets carried by the frame structure, and at least one assembly including a sleeve bearing, an elastomer structure directly coupled with the sleeve bearing, and a retainer, the sleeve bearing being operatively associated with an end of the shaft to support the shaft for rotation, the elastomer structure being 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 being 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 thereof by the retainer.
