Abstract
Disclosed is a method for manufacturing a laminated core, including: a laminated core manufacturing step of manufacturing a laminated core by laminating a lamina member having an adhesive layer formed on a surface thereof; an adhesive layer curing step of curing the adhesive layer by heating the laminated core by high frequency induction-heating; a resin filling step of filling a resin filling part of the laminated core with a resin; and a resin curing step of curing a resin filled in the laminated core. With this method, by curing an adhesive layer with high frequency induction-heating and filling the resin in a state in which a residual heat of the laminated core is maintained, a process for preheating the laminated core for the resin filling may be omitted, and therefore, there is an effect of saving time and expenses consumed in the pre-heating process.
