Abstract

The invention relates to a slip ring assembly featuring a high breakdown voltage between adjacent slip rings (3). To achieve this the rotor (1) is provided with radially extending, cross-sectionally V-shaped grooves (4), the slip rings being positioned at the bottom of the V-shaped grooves. The V-shaped grooves preferably extend into the slip rings, such that also the current collectors (5) rest in a groove.
