Patent ID: 7932659

Claim:
An axial-type superconducting motor constituted as an axial-type and inductor-type motor comprising, around a rotary shaft, an armature side stator including an armature coil attached to an iron core, a pair of rotors including inductors arranged on both sides of the armature side stator, and a pair of field side stators including field coils arranged on both sides of the rotors, the rotors being fitted over and fixed to the rotary shaft, wherein the armature coil and the field coils are each a coil formed of a superconducting wire, a gap is formed between the armature coil and an iron core to which the armature coil is attached, or/and a nonmagnetic material is interposed between the armature coil and the iron core, and gaps are formed between the field coils and the field side stators serving as iron cores, or/and nonmagnetic materials are interposed between the field coils and the field side stators, wherein the field coils are arranged such that an N pole and an S pole are positioned on respective concentric circles, and wherein the inductors in each of the rotors, which inductors serve as magnetic materials during energization of the armature coil and the field coils, are arranged such that an N-pole inductor positioned to face an N pole of the filed coil and an S-pole inductor positioned to face an S pole of the filed coil are alternately located in a circumferential direction.
