<P>PROBLEM TO BE SOLVED: To provide a superconducting motor that efficiently cools superconducting coils to a desired cryogenic temperature while reducing variations in temperature of the superconducting coils even when using the superconducting coils such that a plurality of turns are on one another in a direction perpendicular to a winding axis. <P>SOLUTION: The superconducting motor includes a rotatably arranged rotor, and a stator radially opposed to the rotor and having the coils. The superconducting motor includes a refrigerator 14 having inner contact capillaries 66a and outer contact capillaries 66b for conducting a low temperature refrigerant therein. Each inner contact capillary 66a includes an inner U-shaped portion 96, as a coil contact portion, in contact with one end face of the coil 36 in the winding axis direction. Each outer contact capillary 66b includes an outer U-shaped portion 102, as a coil contact portion, in contact with the other end face of the coil 36 in the winding axis direction. <P>COPYRIGHT: (C)2012,JPO&INPIT |
