Title:
STATOR, ROTATING ELECTRIC MACHINE, AND COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2021/166123
Kind Code:
A1
Abstract:
Provided are a stator, a rotating electric machine, and a compressor. The stator is obtained by winding a coil around a annular stator iron core with an insulating material interposed therebetween. The stator iron core is a linked multilayer iron core that includes a plurality of segment cores which are arranged so as to be annularly linked together and which include first and second segment cores that are disposed adjacent to each other and linked together. The plurality of segment cores are each formed by alternately layering a plurality of plate-shaped first and second members. The first and second members each have a yoke part having a linking section formed at one end thereof and a yoke end formed at the other end thereof. The linking sections of the yoke parts of the first members are each located at an end on the opposite side from a linking section of the yoke part of the second member. The linking sections of the first members of the first segment core are located and interposed between the linking sections of the second members of the second segment core, while abutting the yoke ends of the first members of the second segment core. The first and second segment cores are linked together in a manner that allows the first and second segment cores to freely rotate about the linking sections relative to each other. In addition, a tooth tip of the first segment core is in contact with or fitted with at least a portion of a tooth tip of the second segment core at two ends in the circumferential direction.
