To provide a superconducting motor that efficiently cools superconducting coils to a desired cryogenic temperature while reducing variations in temperature of the superconducting coils.
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 capillaries 66 for conducting a low temperature refrigerant therein, and the capillaries 66 include a coil wrapping portion 100 wrapping the coil 36. The coil wrapping portion 100 has a side straight portion 102 disposed along and in thermal contact with a side plate portion 96 of a peripheral portion of the coil 36 directed to one side of the circumference of the stator, an opposite side straight portion 104 disposed along and in thermal contact with an opposite side plate portion 97 of the peripheral portion of the coil 36 directed to the other side of the circumference of the stator, a coupling portion 106 coupling both straight portions 102, 104.
