Abstract
An outer rotor superconductor journal bearing that comprising modules and including an outer rotor superconductor journal bearing that cools a superconductor that is mechanically fixed to a module below a critical temperature, attains a strong magnetic fixing force in an axial direction and a radial direction, prevents the superconductor from being damaged due to a different thermal expansion between the superconductor and a cryostat when cooled, and is easier for assembling and repair and maintenance. Preferably, the outer rotor superconductor journal bearing includes 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 comprising a cryostat in the shape of a cylinder in which a superconductor that is tightly adhered to an inner circumference of the rotor is mounted in an outer circumference of the cryostat.
