ROTOR HAVING A SUPERCONDUCTING ROTOR WINDING AND AN INTEGRAL SLEEVE SURROUNDING THE ROTOR WINDING

A rotor for a synchronous machine has a rotor axis which defines a rotor shaft. The rotor has a winding support which is arranged on the rotor shaft such that they rotate together, in such a way that it surrounds the rotor shaft in a center section with respect to the rotor axis. The winding support...

Zusammenfassung:A rotor for a synchronous machine has a rotor axis which defines a rotor shaft. The rotor has a winding support which is arranged on the rotor shaft such that they rotate together, in such a way that it surrounds the rotor shaft in a center section with respect to the rotor axis. The winding support is fitted with a superconducting rotor winding. The rotor has a sleeve which at least radially surrounds the winding support and the rotor winding with respect to the rotor axis. The sleeve is formed integrally from a metal alloy, which is non-magnetic, has an electrical conductivity of at least 60% of the electrical conductivity of copper at 20° C., has a mechanical tensile strength of at least 250 N/mm2 at 200° C. and has a 0.2% proof stress of at least 200 N/mm2 at 200° C.
