Rotating electrical machine, especially double-powered asynchronous machine in the output range of 20MVA~500MVA

摘要

The present invention relates to a rotating electric machine, in particular a double-fed asynchronous machine in the output range of 20 MVA to 500 MVA, wherein the rotating electric machine is concentrically surrounded by a stator that rotates about a machine axis. The rotor (14) includes a shaft and a rotor laminated iron core, and the rotor laminated iron core supports a rotor winding disposed on the outer side. The rotor winding relates to a rotating electric machine connected via a connecting body (18a, 18b) to a slip ring arranged inwardly at the end of the shaft. The flexible and safe connection has a mechanical connection (18b) that extends perpendicular to the shaft so that the connection (18a, 18b) absorbs the force generated by centrifugal acceleration, The mechanical connection body (18b) is connected on the one hand to the rotor winding overhang (14) of the rotor winding, and on the other hand, the auxiliary rim (13, 22) provided on the rotor laminated core (12). ) To achieve.
