Superconducting motor of superconducting devices and the axial gap type

摘要

PROBLEM TO BE SOLVED: To miniaturize a superconducting coil by improving structure for fixing the superconducting coil to a core such that superconducting characteristics are not deteriorated by weakening a magnetic field applied to the superconducting coil itself thereby enhancing the current density of the superconducting coil.;SOLUTION: The superconductive device comprises a coil formed of a superconducting material, a core to which the coil is attached, and a magnetic body placed in a magnetic circuit and magnetized by magnetic flux that is generated by energization to the coil and passes the core. An air gap is formed between the coil and the core and/or the nonmagnetic body is interposed between the coil and the core.;COPYRIGHT: (C)2007,JPO&INPIT
