In a coated high-temperature superconducting wirein which a superconducting yttrium-based wire (high-temperature superconducting wire)having a rectangular cross section is coated by an insulating layer, the insulating layeris an electrodeposited film made of block copolymerized polyimide which contains siloxane bonds in a polyimide main chain and which has molecules with anionic groups. A coil formed from the superconducting yttrium-based wireis impregnated with epoxy resin, and the epoxy resin is cured. The coil is configured such that the epoxy resin is completely separated from the superconducting yttrium-based wireby the insulating layer

Coated high-temperature superconducting wire and high-temperature superconducting coil including the same

A stator structure includes: a stator core () having a large number of concave slots () and a large number of convex magnetic poles () circumferentially alternately arranged; and magnet wires () of rectangular cross section in each of which an insulating coating () is formed on the outer surface of a metal wire (), wherein each of the slots () is formed so that the distance (W) between both the side surfaces () of the slot () gradually decreases from the bottom () to a distal opening () of the slot (), each of the magnet wires () is wound around the associated magnetic pole () and inserted in tiers in the associated slot (), and the magnet wire () is placed in the slot () so that the width (W) thereof continuously or stepwise decreases from the bottom () to the distal opening () of the slot ().
