Problems solved by technology

[0005] However, in Japanese Patent No. 2941164, insulating paper is provided between the coil ends of each phase winding. Defective situation where the insulating paper (insulating part) between the ends of the coil is damaged
Therefore, it is considered that there may be a problem that the insulation between the coils cannot be ensured.

[0043] (Stator structure)

[0044] refer to Figure 1 to Figure 19 , the structure of the rotating electric machine 100 (stator 20 ) of the first embodiment will be described. In addition, in the specification of the present application, "the direction of the rotation axis" refers to the direction of the rotation axis of the rotating electric machine 100 (rotor 10 ). In addition, "radial direction" designates the radial direction (radial direction) of the sub 20 . The “inner diameter side” is the inner diameter side of the stator 20 (or the inner peripheral side of the annular coil 30 ), and the “outer diameter side” is the outer diameter side of the stator 20 (the outer peripheral side of the annular coil 30 ).

[0045] Such as figure 1 As shown, the rotating electric machine 100 includes a rotor 10 . A plurality of permanent magnets 12 are provided on a rotor core 11 of the rotor 10 . The plurality of permanent magnets 12 are arranged at substantially equal angular inte...

no. 2 approach

[0089] refer to Figure 21 to Figure 25 , the structure of the rotating electrical machine 101 (stator 120 ) of the second embodiment will be described. In the rotating electric machine 101 (the stator 120 ) of the second embodiment, the insulating member 150 includes the insulating sheet 152 provided so as to overlap the slot housing portion covering portion 151 a of the insulating sheet 151 . In addition, the insulating sheet 151 is an example of the "first insulating sheet" and the "insulating member main body" in the claims. In addition, the insulating sheet 152 is an example of the "second insulating sheet" and the "insulating member main body" in the claims.

[0090] Such as Figure 21 As shown, the insulating sheet 151 includes a slot housing portion covering portion 151 a covering the slot housing portion 31 , and a coil end portion covering portion 151 b covering the coil end portion 32 , as in the first embodiment described above. And, if Figure 22 As shown, the...

Abstract

The present invention provides an insulating component and a stator. In the insulating component, the first insulating sheet includes a folded portion provided at a portion corresponding to the bent portion of the coil, and the first insulating sheet is folded back multiple times so that the first insulating sheet is laminated. .

Description

technical field [0001] The invention relates to insulating components and stators. Background technique [0002] Conventionally, a stator provided with an insulating member is known. Such a stator is disclosed in Japanese Patent No. 2941164, for example. [0003] Japanese Patent No. 2941164 discloses a stator including three-phase windings (coils) disposed in slots of a stator core. In this stator, a winding is formed by winding a conductor wire a plurality of times. In addition, insulating paper is provided between coil ends (parts of the winding protruding from the end surface of the stator core in the rotation axis direction) of the windings of each phase. The insulating paper is configured to insulate between coil ends of the respective phase windings. [0004] Patent Document 1: Japanese Patent No. 2941164 [0005] However, in Japanese Patent No. 2941164, insulating paper is provided between the coil ends of each phase winding. This is a bad situation where the in...
