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, a tightening bolt has its body directly or indirectly in contact with the upper winding through two opposing sides, and against the lower winding through the other two opposing sides, respectively. A stator winding for a rotating electrical machine characterized by being formed in a planar shape and having a rectangular configuration.

(2) Tightening is achieved by indirect contact between the side of the bolt body and the upper or lower winding, and tightening is achieved by indirect contact between the side of the bolt body and the upper or lower winding. A stator winding in a rotating electric machine according to claim 1, wherein the stator winding is brought into contact with a spacer inserted between the stator winding and the rotary electric machine.

(3) The stator winding in a rotating electric machine according to claim 2, wherein the spacer is composed of one or more insulating flat thin plate-like materials.

(4) The stator winding in a rotating electric machine according to any one of claims 1 to 3 of the utility model registration claim, wherein the tightening bolt is a double-headed bolt.

(5) The stator winding in the rotating electric machine according to any one of claims 1 to 4 of the utility model registration claim, wherein the tightening bolt is made of a glass fiber epoxy resin thermosetting laminate material. .
