DYNAMO-ELECTRIC MACHINE

摘要

A dynamo-electric machine is provided comprising a stator and a rotor assembly which is rotatably mounted relative to the stator and which has a rotor shaft. The rotor assembly also has a rotor winding through which current flows and which is connected to terminals associated with the stator in an electrically conductive manner without interruption via a slip ring arrangement. The slip ring arrangement comprises at least two pairs of slip rings, each pair having a stator slip ring and a rotor slip ring that permanently rest against each other in a ring-shaped non-cylindrical contact zone. The two rotor slip rings are arranged between the two stator slip rings. Furthermore, each rotor slip ring is arranged on a rotor support disk that is rotationally fixed to the rotor shaft. The position of the two stator slip rings can be changed relative to each other in the axial direction.
