Abstract (en)
[origin: WO2005074079A1] The invention relates to a brush bag (3), a brush (11) and a current transfer unit for a dynamo-electric machine comprising a commutator (7), in particular for an electromotor. The current transfer unit comprises at least the brush (11), which is embodied, in particular, as a multi-layer carbon brush, and a brush bag (3). The brush bag (3) is configured in such a manner that the distance (11) between the brush (11) and the brush bag (3) in a front guiding area is smaller than the distance (12) in a rear guiding area. Beating of the brush (11) on the brush bag (3) is visibly reduced due to the configuration thereof and noise caused by the beat is avoided.
