Claims

[Scope of utility model registration request]

(1) A stator winding end consisting of a plurality of upper and lower windings protruding from the stator core end, an insulating ring fixed to the outer circumferential side of the stator winding end; A support fixed to the end of the stator core for supporting the insulating ring, and a rotating bolt provided with a tightening bolt for fixing the end of the stator winding to the insulating ring. In electrical machinery, the above-mentioned tightening is arranged between the bolt and the upper end winding, and the above-mentioned tightening is arranged between the bolt and the lower end winding, and the inner surface of the above-mentioned fastening comes into contact with the body of the bolt. It is characterized in that it is formed in a semicircular shape, and the back surface has a two-part spacer piece formed in a planar shape so as to directly or indirectly abut on the upper or lower winding. Stator windings in rotating electrical machines.

(2) The indirect contact of the spacer with the upper or lower winding is through an insulating spacer inserted between the spacer and the upper or lower winding. A stator winding in a rotating electric machine as claimed in claim 1 of the utility model registration claim.

(3) The spacing piece is made of glass fiber epoxy resin thermosetting laminate material.Claim 1 of Utility Model Registration
A stator winding in a rotating electric machine according to item 1 or 2.

(4) A stator winding in a rotating electrical machine according to any one of claims 1 to 3, wherein the tightening bolt is a double-threaded bolt.
