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...
