ABSTRACT:
There is presented an electric motor having a drive shaft, an armature and commutator fixed on the drive shaft, a metal housing disposed around the armature, permanent magnets disposed between the armature and the housing, and an endframe fixed to the housing. A discrete brush card is fixed to the housing and has a central cylindrical portion for retaining the commutator, and brush tubes extending radially from the central portion. The brush tubes are adapted to retain brushes and brush springs for urging the brushes into engagement with the commutator. The brush card is provided with tab portions having orifices therethrough and elastomeric grommets mounted thereon, the grommets having openings extending therethrough and aligned with the tab orifices. The endframe is provided with posts extending from an end wall thereof. The grommet openings are configured to receive, respectively, the posts to lock the grommets onto the posts. The grommets are at least in part disposed between the brush card and the endframe end wall to isolate the brush card from the endframe end wall.
