ABSTRACT:
A superconducting rotating machine includes a stator assembly having at least one stator coil assembly. A rotor assembly, which includes an axial shaft, is configured to rotate within the stator assembly. The rotor assembly includes at least one superconducting winding assembly. A first and second end plate are rigidly attached to the axial shaft at distal ends of the at least one superconducting winding assembly. An asynchronous field filtering shield surrounds the at least one superconducting winding assembly. A first interconnection assembly connects the shield to the first end plate. The first interconnection assembly allows for axial movement between the shield and the first end plate but restricts tangential movement between the same.
