Claims

[Scope of utility model registration request]

In a laminated fixing insulation mechanism for an iron core having a through hole in the core for laminating and fixing the iron core, an insulating plate having approximately the same shape as the iron core that covers one side of the iron core, and an insulating plate that covers one side of the iron core and connects the other side of the iron core and a cut surface of the iron core. a through-hole corresponding to the through-hole of the iron core is provided in the insulating plate, and the insulating frame is provided with a through-hole of the iron core and a through-hole of the insulating plate at a position corresponding to the through-hole of the iron core. A columnar convex portion is provided, the columnar convex portion is passed through the through hole of the iron core and the through hole of the insulating plate, and the portion protruding from the insulating plate is deformed thermally or mechanically, so that the three parts are integrated. A laminated and fixed insulation mechanism of the iron core, which is characterized by its fixed structure.
