Abstract (en)

[origin: US5329198A] In order to be able to ensure with low outlay a slip ring or commutator motor having a high level of freedom from noise and good running quality at maximum power, despite unavoidable deviations from circularity of the slip ring or commutator ground by the brushes abutting thereon, it is proposed according to the invention that the brushes (6; 7; 8) be supported such that they can pivot about an axis which runs radially in the vicinity of the surface and axially essentially in the axial direction of the commutator (1) or slip ring; that, according to one embodiment, the axis be formed by a guide pin (31; 41), which is retained in a brush housing (2) at least partially embracing the brush (6; 7) in the vicinity of the surface of the commutator (1) or the slip ring, and which is plugged axially through a guide slot (61; 71) running in the compression direction of the brush and open towards the surface of the slip ring or commutator (1), or that the brush (6) be tangentially embraced externally by the brush compression spring (3a) in the sense of a support with tangential supporting parts (33a; 34a), which can pivot.
