Document Type and Number:
Japanese Patent JP6639105
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a superconducting rotary electric machine stator for constituting a superconducting rotary electric machine that is reduced in deterioration in a torque as compared with conventional ones, and a method for manufacturing the superconducting rotary electric machine stator.SOLUTION: A superconducting rotary electric machine stator 3 includes: a plurality of superconducting coils 32; and a stator core 31 formed in a hollow cylindrical shape that has an inner peripheral wall surface 31in and an outer peripheral wall surface 31out, a plurality of inside slots 311 being extended to the inner peripheral wall surface in an axial direction and a plurality of outside slots 312 being extended to the outer peripheral wall surface in an axial direction. A first straight line portion 321 of each of the superconducting coils 32 is arranged in each of the inside slots 311, and a second straight line portion 322 of each of the superconducting coils 32 is arranged in each of the outside slots 312. The stator core 31 is divided in a circumferential direction.SELECTED DRAWING: Figure 7
