ABSTRACT:
A brush assembly for use with a commutator of a dynaomoelectric machine comprises an electrically insulating housing having an integral main body and a flat planar cover which, when assembled, define together a plurality of radially extending brush holders between them. Brush elements are slidably disposed within the brush holders of the housing, and brush springs are disposed for biasing the brush elements radially inwards to establish a pressure contact with the commutator segments of the dynamoelectric machine. In order to hold the cover and the main body together in an assembled condition, holding elements mountable to the dynamoelectric machine while maintaining the assembled condition of the cover and the housing main body are provided.
