SUPERCONDUCTING MOTOR

摘要

PROBLEM TO BE SOLVED: To provide a superconducting motor capable of efficiently cooling a coil consisting of a superconducting wire rod to a desired cryogenic temperature.

SOLUTION: A superconducting motor 10 comprises: a rotor 12 supported rotatably; a stator 14 which is provided to cover the circumference of the rotor 12 and in which a plurality of coils 34 composed of a superconducting wire rod are wound around an inner peripheral part of a stator core 30; and a plurality of refrigerators 16 and 17 each including cooling parts 58. A coil end part 36 of each coil 34 positioned at both ends in the axial direction of the stator 14 is cooled from both sides of the axial direction by the cooling parts 58 of a plurality of refrigerators 16 and 17.
