Claims

[Scope of Claim for Utility Model Registration] An insulating holding plate disposed on the inner circumferential side of the end of the stator winding consisting of a plurality of upper and lower windings protruding from the end of the stator core; , a plurality of spacing pieces inserted between the upper and lower windings, a plurality of insulating bottom plates arranged on the outer peripheral side of the stator winding ends, and a plurality of wedge elements made of an insulator. and an insulating ring disposed on the outer peripheral side of the insulating floor plate through the
The wedge elements include a first wedge located on the insulating ring side and thicker on the stator core side, and a second wedge located on the insulating floor plate side and thinner on the stator core side,
1. In a stator winding end support device for a rotating electric machine, the second wedge is pushed into the stator core side by a metal bolt screwed into a screw hole of the first wedge. The diameter of the threaded part that is screwed into the screw hole is the same as the diameter of the bolt body (
A stator winding end support device for a rotating electric machine, characterized in that the bolt is larger than the bolt.
