Claims (5)

An insulator formed by an iron core, a main body portion, and a U-shaped pressing portion that is provided on the main body portion and extends along the teeth portion of the iron core; And an insulating sheet fixed to the insulator and a winding wound around the tooth portion provided with the insulating sheet fixed by the insulator, and a plurality of the iron cores are joined in a ring shape. The winding is a stator of a rotating electric machine that deforms so as to swell when energized during built-in magnetization ,
The insulating sheet is formed by a mounting portion that is mounted on the tooth portion and an extending portion that extends from both ends of the mounting portion, and the mounting portions are installed at both ends in the axial direction of the iron core. It is installed between the thin parts of the pressing part of the insulator, and the extension part is installed so as to cover the winding that is overlapped and exposed to the opening side of the insulator . A stator for a rotating electrical machine, wherein the extension portion is overlapped and covers the winding .   The length of the extension portion of the insulating sheet in the direction parallel to the axial direction of the iron core is longer than the length of the mounting portion of the insulating sheet, and the extension portion of the insulating sheet protrudes from the iron core in the axial direction of the iron core The stator for a rotating electrical machine according to claim 1, wherein   The insulating sheet is formed of a first insulating sheet and a second insulating sheet stacked on the center of the mounting portion of the first insulating sheet, and is parallel to the axial direction of the iron core of the second insulating sheet. 3. The stator for a rotating electrical machine according to claim 1, wherein a length in one direction is shorter than a length in a direction parallel to the axial direction of the iron core of the first insulating sheet.   The stator of the rotating electrical machine according to claim 3, wherein a distance between an end portion in a direction parallel to the axial direction of the iron core of the second insulating sheet and an end portion of the pressing portion of the insulator is 5 to 10 mm. . The winding is formed by concentrated winding, wound on the side surface parallel to the axial direction of the iron core with aligned winding, and wound so as to be sent in one of the upper and lower ends of the iron core. The stator for a rotating electrical machine according to any one of claims 1 to 4, wherein the stator is a rotating electrical machine.
