Method for manufacturing laminated core

Abstract

Provided is a method for manufacturing a laminated core capable of reducing the likelihood that the iron loss increases while increasing the space factor of the laminated core. A method for manufacturing a laminated core includes a laminating step of laminating a plurality of thin plates made of a soft magnetic material, an impregnating step of filling a resin into spaces between the plurality of thin plates laminated, and a fixing step of curing the filled resin to fix the plurality of thin plates laminated. In the fixing step, the resin is cured while applying a pressure larger than 0 MPa and equal to or smaller than 1.5 MPa to the plurality of thin plates laminated in a laminating direction of the plurality of thin plates.
