Patent ID: 7282832

Claim:
A superconducting rotating machine comprising: a stator assembly including at least one stator coil assembly; and a rotor assembly, including an axial shaft, which is configured to rotate within said stator assembly, said rotor assembly including: at least one superconducting winding assembly; a first end plate and a second end plate, each being rigidly attached to said axial shaft at distal ends of said at least one superconducting winding assembly; an asynchronous field filtering shield which surrounds said at least one superconducting winding assembly; and a first interconnection assembly for connecting said shield to said first end plate, said first interconnection assembly being configured to allow axial movement between said shield and said first end plate and restrict tangential movement between said shield and said first end plate; wherein the superconducting rotating machine further comprises a vacuum chamber sleeve which surrounds said at least one superconducting winding assembly and is positioned between said shield and said at least one superconducting winding assembly, wherein the distal ends of said sleeve are rigidly attached to said end plates of said rotor assembly.
