Patent ID: 7659646

Claim:
An outer rotor superconductor journal bearing comprising: a rotor in which a solid of revolution magnet is magnetized in an axis direction in an inner portion of an inner circumference thereof; and a stator constituting a cryostat in the shape of a cylinder in which a plurality of superconductors that are tightly attracted by magnetic force to an inner circumference of the rotor is mounted in an outer circumference of the cryostat; wherein the cryostat comprises the superconductor in any one of the sides of the rounded outer circumference thereof, a module base in which the superconductors are mounted, and a fixing plate supporting the upper and lower surfaces of the superconductors so that the superconductors are spaced apart from each other by a predetermined gap between the upper and lower surfaces of the plurality of superconductors, and an inner material of the fixing plate is weaker than the superconductors in terms of the strength so that the superconductors are prevented from being damaged by a cooling contraction of the modules.
