Patent ID: 8643240

Claim:
A stator for use in a superconducting rotating electrical machine, the rotating electrical machine comprising a rotor with superconducting windings and said stator mounted around the rotor, comprising: a number of teeth disposed at a regular interval about a rotational axis of the rotor to define slots each between adjacent teeth; and a plurality of windings, each winding having a strip-like wire member, said wire member having a plurality of rectangular cross-section wires in which said rectangular wires are arranged in parallel to each other and electrically insulated away from each other, said winding being constructed by winding said strip-like wire member a plurality of times to have first and second winding portions having a cross section in which said rectangular wires are positioned in matrix, said first and second winding portions having the same arrangement of said wires in a cross section perpendicular to said rotational axis, said first winding portion being disposed in an outward region of one of said slots and said second winding portion being disposed in an inward region of another of said slots corresponding to said one of said slots.
