Dust core and method of manufacturing the same

摘要

A stator core includes first and second annular dust core pieces. Each of the first and second annular dust core pieces has a plurality of arcuate dust core pieces each integrally having a yoke extending in an arc shape and a tooth projecting in a radial direction of the yoke. The plurality of arcuate dust core pieces are each disposed along a circumferential direction of the yoke and joined together, and the first and second annular dust core pieces are stacked in a height direction and joined together. Thereby, an increase in size of a pressing machine can be suppressed, good magnetic properties can be obtained, and handling can be facilitated.
