Patent ID: 7948131

Claim:
A superconducting magnetic thrust bearing with integrated dynamotor comprising: a superconducting coil; a first fixed core having a cylindrical shape and arranged so that a central axis thereof coincides with that of the superconducting coil; a rotary core having a cylindrical shape and arranged on the inside or outside of the first fixed core so that a central axis thereof coincides with that of the superconducting coil; and an armature core having a plurality of armature coils arranged in a winding direction of the superconducting coil, wherein the first fixed core is formed to have a U-shaped cross-section in a direction of the central axis of the cylindrical shape with an opening of the U-shape being directed perpendicularly to the central axis, wherein the superconducting coil is arranged on the inside of the U-shaped portion of the first fixed core formed into the U-shape, wherein the rotary core has projecting ends at positions opposite to two projecting ends of the U-shape of the first fixed core, and a magnetic flux guide path, at a position opposite to the armature core, with a shape varying at predetermined intervals in the winding direction of the superconducting coil, and is constituted in such a way that said rotary core rotates relatively to the first fixed core and is able to move in the direction of the central axis of the first fixed core, and wherein the armature core is arranged fixedly in a magnetic flux path that introduces a magnetic flux, said magnetic flux is generated from the superconducting coil and led out from one of the two projecting ends of the U-shape of the first fixed core, to the projecting ends of the rotary core and leads out the magnetic flux from the projecting ends of the rotary core.
