More Information
Summary:적층 코어는, 서로 적층되고, 양면이 절연 피막에 의해 피복된 복수의 전자 강판과, 적층 방향으로 인접하는 전자 강판끼리의 사이에 마련되고, 전자 강판끼리를 각각 접착하는 접착부를 구비하고, 접착부에 의한 전자 강판의 접착 면적률이 1％ 이상 40％ 이하이다. A laminated core includes a plurality of electrical steel sheets stacked on each other and coated with an insulation coating on both surfaces thereof, and an adhesion part provided between the electrical steel sheets adjacent to each other in a stacking direction and configured to adhere the electrical steel sheets to each other, wherein an adhesion area ratio of the electrical steel sheet by the adhesion part is 1% or more and 40% or less.
