To provide a superconducting rotor for large-capacity superconducting rotary electric machine having excellent excitation controllability without using any twisted superconductor having a large current capacity in the case of increasing the capacity of a superconducting rotary electric machine, such as the superconducting generator, etc.
In a superconducting rotor for large-capacity superconducting rotary electric machine provided with field windings formed by forming magnetic poles by winding superconductors in slots provided on the surface of a winding fitting shaft and current leads 11 for supplying electric current to the field windings, the field winding of each pole is constituted of a plurality of parallel circuits 13NA, 13NB, 13SA, and 13SB, of superconductors having small current capacities. Then the parallel circuits 13NA, 13NB, 13SA, and 13SB, are combinedly connected in series so that the self-inductances of the parallel circuits can become nearly equal to each other.
