Claims

[Scope of utility model registration request]

(1) A press plate on the inner circumferential side of the stator winding end, which consists of a plurality of upper windings and lower windings protruding from the stator core end;
A spacing piece between the upper and lower windings, a bottom plate on the outer periphery side, and further driven in the axial direction on the outer periphery side, and the inclined surfaces are slidably abutted in the inclined direction so that the back surfaces operate parallel to each other. Through a wedge device consisting of two wedges configured to
In a stator winding of a rotating electrical machine, each of which is provided with an insulating ring, the two (holts) of the wedge device that slide the wedges in a relatively inclined direction are composed of double-threaded bolts and nuts made of an insulator. A stator winding for a rotating electric machine characterized by:

(2) The stator winding for a rotating electrical machine according to claim 1, wherein the insulator constituting the bolts and nuts is an epoxy resin glass roving material.
