Abstract

See full text

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 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. 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.
