Laminated iron core, laminated iron core manufacturing method, and armature using laminated iron core

摘要

A method of manufacturing a laminated core according to the present invention includes a laminated body that is configured by laminating core pieces made of a magnetic material, and has a core back portion and a teeth portion that protrudes radially inward from an inner peripheral surface of the core back portion; An insulating member disposed on both sides of the tooth portion, and a method of manufacturing a laminated iron core, wherein the insulating member is pressed against each side surface of the tooth portion of the laminated body, The laminate includes a bonding step of integrating the laminated body and fixing the insulating member to the laminated body by at least one of an adhesive and a pressure-sensitive adhesive disposed between a side surface and the insulating member.
