摘要:
The present adhesively-laminated core for a stator includes: a plurality of electrical steel sheets coaxially overlapping each other, and each of which having a core back part and a tooth part; and a plurality of adhesion parts which adheres between the electrical steel sheets, in which, between the respective electrical steel sheets, a partial adhesion strength provided by the adhesion parts and being an average adhesion strength per unit area in the tooth part, is lower than a partial adhesion strength provided by the adhesion parts and being an average adhesion strength per unit area in the core back part.
