Abstract
Official abstract text for this publication.
An electric motor stator includes a stator core in a tubular shape, which stator core has slots in which insulating paper and a winding are fixed with varnish, and at a first temperature obtained by heating, an adhesive force of an adhesive provided on at least one side of a base material of the insulating paper is less than an adhesive force of the varnish.
First claim
Opening claim text (preview).
What is claimed is: 1 . An electric motor stator, comprising a stator core in a tubular shape, the stator core having slots in which insulating paper and a winding are fixed with varnish, wherein, at a first temperature obtained by heating, an adhesive force of an adhesive provided on at least one side of a base material of the insulating paper is less than an adhesive force of the varnish. 2 . The electric motor stator according to claim 1 , wherein, at the first temperature, adhesive forces of adhesives provided on opposite sides of the base material are less than the adhesive force of the varnish. 3 . The electric motor stator according to claim 1 , wherein a relationship is provided, at the first temperature, in which an adhesive force of a winding side adhesive is less than an adhesive force of a core side adhesive, and the adhesive force of the core side adhesive is less than the adhesive force of the varnish, the winding side adhesive being provided on a side of the winding of the base material, the core side adhesive being provided on a side of the stator core of the base material. 4 . The electric motor stator according to claim 1 , wherein, at a room temperature or a second temperature corresponding to a temperature before heating, adhesive forces of adhesives on opposite faces of the base material are equal to or less than the adhesive force of the varnish. 5 . The electric motor stator according to claim 1 , wherein the insulating paper has a multi-layer structure including the base material and surface materials bonded to opposite sides of the base material, and at the first temperature, adhesive forces of adhesives respectively between the base material and each of the surface materials are less than the adhesive force of the varnish. 6 . The electric motor stator according to claim 1 , wherein the electric motor stator is a stator used for a vehicle electric motor.
