Zusammenfassung:A synchronous alternating current machine having a superconducting field winding on a hollow cylindrical portion of a rotor which is joined by hollow frustoconical transition members to supporting stub shafts. The field winding is cooled by cryogenic fluid from a refrigerator, which may be wholly or partly within the rotor, and heat leak into the winding is minimized by the hollow transition members, which are themselves cooled, and a radiation shield mounted on the outside of the rotor.
