PURPOSE:To eliminate a noise, by providing a permanent magnet in either a stator or a rotor and an annular structure, which is wound by a superconducting coil to be mounted in the other and providing the rotor with a bearing function. CONSTITUTION:A superconductor motor mounts a thin disk-shaped permanent magnet 3', having an outside diameter larger then that of a disk-shaped permanent magnet 3, to its one surface and arranging a shaft 11, penetrating through the permanent magnet 3, to its center. The motor mounts a permanent magnet 1 by a screw 7 to an opposite side surface of both the magnet 3, 3', forming a rotor 30. The motor forms a superconducting film 13 on the outer periphery of the permanent magnet 3 of the rotor 30 providing a predetermined space respectively from the permanent magnets 1-3, while arranging a number of superconducting plates 14 with a predetermined space in the inside thereof. The motor arranges stators 31 consisting of an annular permanent magnet 12 having one superconducting coil 4. Accordingly, the motor, in which the rotor 30 rotates in a condition with no mechanical contact by a bearing or a brush or the like, enables the rotor to semipermanently continue its rotary motion. |
