Abstract
A superconducting rotating machine includes a stator that includes a cylindrical stator iron core and a stator winding that is toroidally wound around the stator iron core and formed of a superconducting material, and generates a rotating magnetic field, an inner rotor rotatably held at an inner circumferential side of the stator, and an outer rotor rotatably held at an outer circumferential side of the stator. The inner and outer rotors each include at least one rotor winding selected from a superconducting squirrel cage winding including a single or a plurality of rotor bars and end rings that are formed of a superconducting material, and a normal conducting squirrel cage winding including a single or a plurality of rotor bars and end rings that are formed of a normal conducting material, and a rotor iron core including a plurality of slots that accommodate respective rotor bars of the rotor winding.
