Embodiment Construction

[0022] Below, while referring to the attached Figure 1 The rotating electric machine 100 of this embodiment will be described. Such as figure 1 As shown, in the rotating electrical machine 100 of the present embodiment, the coil end 35 on the lead wire side (Japanese: リード side) of the stator 10 is integrally molded with the sheath support 40 by resin 50 , and the lead wire opposite side (Japanese: リード side) is molded integrally by resin 60 . : Reverse リ ー ド side) of the coil end 36 and the sheath support 40 molded as one. also, figure 1 The illustrated stator 10 is provided with an input / output terminal (not shown) of the coil 30 on the coil end 35 side, so in the following description, the coil end 35 side of the stator 10 is referred to as the lead side, and the coil end is referred to as the lead wire side. The 36 side is called the opposite side of the lead. The resins 50 and 60 are examples of resin components.

[0023] Such as figure 2 As shown, the stator 10 is ...

Abstract

A rotary electric machine includes: a stator core including an annular yoke, a plurality of teeth, and a plurality of slots; a resin member; an annular cuff support having a plurality of ribs and a plurality of openings; and a coil including an annular coil end. A cylindrical outer-peripheral flange is provided such that the outer-peripheral flange is apart from the coil end, and the outer-peripheral flange is opposed to the coil end, the resin member is provided such that the resin member is apart from the cuff support, and the resin member covers a part of the outer-peripheral flange and thecoil end, and the outer-peripheral flange, the coil end, the resin member, and the cuff support define a first gap among the outer-peripheral flange, the coil end, the resin member, and the cuff support.

Description

technical field [0001] The present invention relates to a structure of a rotating electric machine, and in particular, to a rotating electric machine provided with a structure for cooling coil ends. The rotating electric machine of the present invention is mounted on a vehicle as, for example, an electric motor for driving the vehicle. Background technique [0002] Rotating electric machines such as electric motors and motor generators generate losses such as copper losses, iron losses, and mechanical losses along with driving, and generate heat corresponding to these losses. When the temperature of the rotating electric machine becomes too high due to the heat generation, deterioration of components, demagnetization of permanent magnets, and the like may occur. Therefore, conventionally, there has been proposed a technique for cooling the stator coil by spraying a liquid as a refrigerant, such as cooling oil, onto a coil end portion of the stator coil protruding axially ou...
