Superconducting magnetic thrust bearing with integrated dynamotor

Abstract

In a superconducting magnetic thrust bearing with integrated dynamotor, a 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, and a superconducting coil is arranged on the inside of the U-shaped portion of the first fixed core formed into the U-shape. A 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 an armature core, with a shape varying at predetermined intervals in the winding direction of the superconducting coil. The rotary core is constituted such that it rotates relatively to the first fixed core and is able to move in the direction of the central axis of the first fixed core. The armature core is arranged fixedly in a magnetic flux path that introduces a magnetic flux, which 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.
