Abstract:
The invention proceeds from a rotating electric machine, in particular a double-fed induction machine in the power range between 20 MVA and 500 MVA, which comprises a rotor (14) that rotates about a machine axis, is concentrically surrounded by a stator, and has a rotor plate body and a shaft, which rotor plate body bears a rotor winding that is arranged further outwards and is connected by means of connectors (18a, 18b) to slip rings that are arranged further inwards at the end of the shaft. A flexible and secure connection is achieved in that the connectors (18a, 18b) have mechanical connectors (18b) that run at right angles to the shaft to absorb forces arising owing to centrifugal acceleration, which mechanical connectors are connected on one side to a rotor winding head (14) of the rotor winding and are supported on the other side on an auxiliary rim (13, 22) on the rotor plate body (12).
