Abstract
A superconducting device includes a coil formed of a superconducting wire, an iron core to which the coil is attached, and a magnetic material arranged in a magnetic circuit and magnetized by magnetic flux. The magnetic circuit is generated by energization of the coil and passes through the iron core. A gap is formed between the coil and the iron core, or/and a nonmagnetic material is interposed between the coil and the iron core.

A superconducting device comprising:
- a coil formed of a superconducting wire;
- an iron core to which the coil is attached;
- and
- a magnetic material arranged in a magnetic circuit and magnetized by magnetic flux, the magnetic circuit being generated by energization of the coil and passing through the iron core,
- wherein a gap is formed between the coil and the iron core, or/and a nonmagnetic material is interposed between the coil and the iron core.
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.
