Embodiment Construction

[0054] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following description, the same reference numerals are assigned to the same components. The names and functions of these parts are also the same. Therefore, detailed descriptions of these components are not repeated.

[0055] The stator of the present embodiment is a stator of a rotary electric machine including a stator and a rotor formed of permanent magnets. In this embodiment, the stator is a stator of a three-phase AC synchronous rotating electrical machine with 21 poles, but the present invention is applicable to a stator wound with coils, and is not particularly limited to 21 poles, and is not limited to three The stator of an AC synchronous rotating electrical machine.

[0056] Such as figure 1 As shown, the stator 100 includes a stator core 102 , a coil subassembly 108 , laminates 110 , 112 as bridging members, and bus bars 114 .

[0057] The stator c...

Abstract

A stator includes a stator core (102) having a plurality of slots (106) in a direction parallel to the rotating shaft of a rotating electrical machine; and a coil plate laminated body formed by laminating a plurality of I-shaped coil plates, each of which has an insulating film adhered at least on one side, in a diameter direction. In the coil plate laminated body, a plurality of coil plates are inserted inside a resin insulator inserted into the slots (106) so that the insulating film is arranged between the coil plates, and the coil plates are integrally held by the resin insulator. The resin insulator integrally holds the coil plate laminated body of a plurality of phases in the same slot.

Description

technical field [0001] The present invention relates to a stator of a rotating electric machine, a part used for the stator, and a method of manufacturing the stator of the rotating electric machine, and more particularly, to a stator having a structure for improving insulation and productivity, a part used for the stator, and a method of manufacturing the stator. Background technique [0002] Conventionally, among stators of rotating electric machines composed of a stator and a rotor, a stator formed by inserting an integral laminated coil into slots provided between a plurality of teeth provided on a stator core has been disclosed. For example, an integral laminated coil is integrally formed by resin molding two sets of coil laminates formed by laminating a plurality of linear thin-plate conductors. By stacking thin plate-shaped conductors so that the cross-sectional area of ​​the slot in the direction perpendicular to the rotation axis is close to that of the slot, the ar...
