摘要:
Provided is an adhesively-laminated core for a stator including: a plurality of electrical steel sheets which have phosphate-based insulation coatings on surfaces thereof and are overlapped coaxially with each other; and adhesion parts provided between the respective electrical steel sheets, an average thickness of the insulation coatings is 0.3 μm to 1.2 μm, an average thickness of the adhesion parts is 1.0 μm to 3.0 μm, and in a case where the average thickness of the insulation coating is defined as t1 in a unit of μm, and the average thickness of the adhesion parts is defined as t2 in a unit of μm, the following Equation 1 is satisfied. −4.3×t1+3.6≤t2≤−4.3×t1+6.9 (Equation 1)
