Problems solved by technology

In addition, when the insulating member is caught between the guide jig and the tooth, a part of the tooth not covered by the insulating member is generated, so that insulation failure of the stator occurs.

Embodiment Construction

[0037] Hereinafter, embodiments of the present invention will be described based on the drawings.

[0038] [Structure of this embodiment]

[0039] [Structure of Stator]

[0040] refer to Figure 1 ~ Figure 4 The structure of the stator 100 of this embodiment will be described. In addition, in figure 1 In , the stator 100 is formed in a circular ring shape, although a sectional oblique view (semicircular shape) of the stator 100 is shown.

[0041] In addition, in the specification of this application, "central axis direction" and "axial direction" mean along figure 1 The direction (Z direction) of the center axis A (rotation axis of the rotor) of the stator core 10 (stator 100 ) is shown. In addition, "circumferential direction" designates the circumferential direction (B1 direction or B2 direction) of the sub-core 10 . In addition, “radial direction” designates the radial direction of the sub-core 10 . In addition, “radially inward” refers to a direction (direction C1 )...

Abstract

This stator assembly method comprises: a step for positioning a guide portion that restricts the movement in the circumferential direction of an opening tool that is inserted into a slot; and a step in which, while guiding the opening tool in such a manner that movement of the opening tool in the circumferential direction is restricted by the guide portion, the coil and the opening tool are both moved in the other direction in the radial direction with respect to the stator core, thereby inserting the slot housing into the slot.

Description

technical field [0001] The invention relates to a stator assembling method and a stator assembling device. Background technique [0002] Conventionally, a stator assembling method and a stator assembling device in which insulating members are arranged in slots are known. Such a stator assembling method and a stator assembling device are disclosed in, for example, International Publication No. 2019 / 031573. [0003] The stator assembling method described in the above-mentioned International Publication No. 2019 / 031573 includes a step of inserting a guide jig (opening jig) inside a sheet-shaped insulating member arranged in a slot along the central axis direction of the stator core. In addition, in the above-mentioned International Publication No. 2019 / 031573, it is described that by moving the guide jig inserted into the inner side of the insulating member and the coil provided on the radially inner side of the guide jig to the radially outer side, the insulating member is mo...
