Abstract
A superconducting electric motor includes: a rotor that is rotatably arranged; and a stator. The stator has a plurality of teeth provided on one radial end portion of a stator core and slots, each of which is provided between two of the plurality of teeth, adjacent in a circumferential direction of the stator. Coils are respectively wound around the teeth. The superconducting electric motor further includes a refrigerator that has a narrow tube that flows low-temperature refrigerant inside. At least part of the narrow tube is arranged between two of the coils, adjacent in the circumferential direction of the stator, in one of the slots.
