<P>PROBLEM TO BE SOLVED: To provide a superconducting motor that is applied with an alternating current and does not spoil cooling efficiency of a superconducting wire while suppressing hysteresis loss of the superconducting wire. <P>SOLUTION: There is provided an axial gap type superconducting motor characterized in that a stator 1 has a pair of superconducting wires 12a, 12b extending radially from a rotating shaft 2 as a center in point symmetry relationship, rotors 21, 22 are configured to have pairs of permanent magnets 21a, 21b and 22a, 22b with mutually opposite polarities in a direction of the rotating shaft allocated to two halved regions across a diameter having its center on the rotating shaft, an alternating current is supplied to one of the superconducting wires 12a, 12b in the point symmetry relationship from an inner periphery to an outer periphery, and an alternating current in phase is supplied to the other of the superconducting wires 12a, 12b from an outer periphery to an inner periphery. <P>COPYRIGHT: (C)2013,JPO&INPIT |
