Abstract (en)
[origin: EP0547437A2] The invention relates to a brush guidance arrangement for electrical machines, in the case of which the commutation brushes (5) are arranged, with a helical compression spring (3), in a prismatic guide tube (1). Cost-effective and low-friction guidance of these commutation brushes (5) and of the compression spring (3) is achieved in that bulges (13, 15) are arranged in the two large-area side walls of the guide tube (1), with which bulges (13, 15) the compression spring (3) is in linear contact. <IMAGE>
