Title:
The stator of a superconductivity rotating machine, a superconductivity rotating machine
Document Type and Number:
Japanese Patent JP6029934
Kind Code:
B2
Abstract:
A unit winding (40(K)) is formed by bundling a plurality of insulating conductor strands (a1 to f7). A unit winding (44) disposed in a first sectional region (S1) of a first slot from one end in an axial direction of a stator toward the other end in the axial direction is turned back in such a manner that positions of the insulating conductor strands are inverted in the axial direction from inside to outside and from outside to inside at the other end (non-connection side). Then, the unit winding (45) is disposed into a third sectional region (S2) of a second slot from the other end in the axial direction toward the one side in the axial direction, and turned back in such a manner that the positions of the insulating conductor strands are inverted in a circumferential direction from one side to the other side and from the other side to one side at the one end in the axial direction (connection side). Then, the turned back unit winding (46) is disposed into the second sectional region (S3) of the first slot from the one end in the axial direction toward the other side in the axial direction, and turned back in such a manner that positions of the insulating conductor strands are inverted in the axial direction from inside to outside and from outside to inside at the other end in the axial direction. Then, the unit winding (47) is disposed in a fourth sectional region (S4) of the second slot from the other end in the axial direction toward the one end in the axial direction.
