Abstract

The present invention relates to an electrical machine (1) having a rotor (2), to which a winding (5) for the generation of an electromagnetic field and a slip ring (10) of an apparatus (9) for the supply of electrical energy to the winding (5) are fitted in a non-rotational manner, wherein the slip ring (10) cooperates with a brush (12) of the apparatus (9). A prolonged service life and/or more reliable operation of the electrical machine (1) are achieved by virtue of the fact that a housing (7), in which the slip ring (10) and the brush (12) are arranged, is configured in a fluidically sealed arrangement vis-a-vis the exterior, and the housing (7) is provided with a housing part (16), which is fluidically connected to an annular gap (19) between the slip ring (10) and the housing (7) via two flow openings (20, 21) which are mutually spaced in the circumferential direction (15).
