Abstract
A superconducting electric motor includes: a rotor rotatably arranged; a stator arranged in a radial direction of the rotor to face the rotor; and a refrigerator having at least one narrow tube that flows low-temperature refrigerant inside. The stator has a plurality of superconducting coils wound at a radial end portion of a stator core and formed of a superconducting wire material. The at least one narrow tube has a core penetrating portion that is provided to penetrate through the stator core. Alternatively, the refrigerator has a plurality of narrow tubes, and at least part of each narrow tube is provided in the stator core. Connecting portions that are refrigerant supply/drain connecting portions at both ends of each of the plurality of narrow tubes are provided on both axial sides of the stator at opposite sides in a diametrical direction with respect to a rotation central axis of the rotor.
