생산성이 우수하고, 기계 강도가 높고, 회전 전기 기기의 진동이나 소음을 저감하고, 철손을 억제할 수 있는 스테이터용 접착 적층 코어를 구비한 회전 전기 기기를 제공한다. 서로 적층되며, 양면이 절연 피막에 의해 피복된 복수의 전자 강판과, 적층 방향으로 인접하는 전자 강판끼리의 사이에 배치되며, 이들 전자 강판끼리를 접착하는 접착부를 구비하고, 적층 방향으로 인접하는 전자 강판끼리의 모든 조가 접착부에 의해 접착되고, 접착부를 형성하는 접착제가 속경화형 접착제 및 열경화형 접착제이고, 적층 방향으로 인접하는 전자 강판끼리의 사이에 있어서, 접착부가 부분적으로 마련되어 있는 스테이터용 접착 적층 코어. Provided is an electric motor which includes an adhesively-laminated core for a stator having excellent productivity and high mechanical strength and that is thus capable of reducing vibration and noise of an electric motor and suppressing iron loss. The adhesively-laminated core for a stator includes a plurality of electrical steel sheets laminated on each other and each coated on both sides with an insulation coating, and an adhesion part disposed between the electrical steel sheets adjacent to each other in a stacking direction and configured to cause the electrical steel sheets to be adhered to each other, in which all sets of the electrical steel sheets adjacent to each other in the stacking direction are adhered by the adhesion part, an adhesive forming the adhesion part includes a fast-curing type adhesive and a thermosetting adhesive, and the adhesion part is partially provided between the electrical steel sheets adjacent to each other in the stacking direction.
