The invention relates to a guidance device (10) of a suction system, said suction system being designed to suck up the dust generated by a brush (1) rubbing against a rotary element (2) in a rotary electrical machine, the guidance device (10) being designed in such a way as to concentrate a stream of air (F) generated by the suction system, near the end of the brush that is in contact with the rotary element (2). The guidance device defines at least one suction chamber (12) shaped so that it opens towards the rotary element, said at least one chamber having walls extending in a longitudinal direction so that said assembly is shaped so as to surround part of a brush near said end. The invention also relates to a suction system comprising such a guidance device. |
