PROBLEM TO BE SOLVED: To provide a new superconduction rotary machine which skillfully utilizes superconduction characteristics to achieve a small and lightweight structure and high efficiency without supplying power from the exterior to a superconductor incorporated in a rotor.SOLUTION: A superconduction rotary machine is composed of: an armature coil 2 provided at a stator 1; a plate like superconductor 4 that is housed and disposed in a hollow rotation part 3a of a rotor so as to be aligned with a rotation center of the rotor 3 and is formed by a rectangular thin film superconductor. An electromagnetic force is generated by mutual action of a shield current, induced on the plate like superconductor 4 by applying a magnetic field (a rotary magnetic field) that is generated by the armature coil 2 with the superconductor 4 cooled in a superconduction state, and the armature magnetic field. Rotation torque is generated in the rotor 3 on the basis of the electromagnetic force to rotationally drive the rotor. |
