ABSTRACT:
A slip-ring arrangement for electrical machines,especially asynchronous machines, for the directional elimination of heat and for the removal of brush abrasion elements having several slip rings, located next to one another, the slip rings being provided with axial cooling-gas bores which are intersected by grooves or slots in each slip-ring surface. These cooling-gas bores are guided--separately for each slip ring--through axially extending insulating tubes to a suction fan, preferably a radial fan so that heat lost is eliminated directly at its point or origin.
