Problems solved by technology

[0007] However, when the wall body is provided on the inner peripheral surface side of the stator than the outlet opening of the cooling medium, the cooling medium flowing out from the outlet opening is blocked by the wall body, so the cooling medium may not easily scatter to the coils of the stator, and it may not be possible to Efficient cooling of coils

[0028] figure 1 It is a schematic configuration diagram showing the overall configuration of the rotating electrical machine 1 according to the first embodiment. figure 1 It is a figure including the cross section cut with the imaginary plane containing the axis C.

[0029] like figure 1 As shown, the rotating electric machine 1 includes a housing 2, a stator 3, a rotor 4, an output shaft 5, and a cooling medium supply mechanism (not shown).

[0030] The case 2 is formed in a cylindrical box shape for accommodating the stator 3 and the rotor 4 . A cooling medium (not shown) is accommodated in the casing 2 . A part of the stator 3 is arranged in a state immersed in the cooling medium in the housing 2 . For example, ATF (Automatic Transmission Fluid), which is hydraulic oil used for transmission lubrication, power transmission, and the like, is used as the cooling medium.

[0031] The output shaft 5 is rotatably supported by the housing 2 . exist figure 1 In , ...

Abstract

The invention provides a rotating electrical machine capable of being improved in rotating efficiency and efficiently cooling a coil. The rotating electrical machine is provided with: a stator havinga cylindrical stator core and a coil attached to the stator core; and a rotor (4) disposed on the inside in the radial direction of the stator, the rotor (4) being provided with: a rotor core (21) having a rotor internal flow path through which a cooling medium capable of cooling the axial center flows; and an end plate (23) disposed at an axial end of the rotor core (21). The end plate (23) has:a cooling medium flow hole (30) that communicates with the rotor internal flow path; and a cooling medium passage groove (31) that connects the cooling medium flow hole (30) and the outer peripheral edge (23a) of the end plate (23), and the radially outer groove width of the cooling medium passage groove (31) is equal to or less than the radially inner groove width when viewed from the axial direction.

Description

[0001] This application is based on Japanese Patent Application No. 2019-003256 (filing date 2019.1.11) and enjoys priority benefits from this application. This application refers to this application, thereby including the entire content of this application. technical field [0002] This invention relates to rotating electric machines. Background technique [0003] In a rotating electrical machine mounted on a hybrid vehicle, an electric vehicle, etc., a magnetic field is formed in a stator core by supplying a current to a coil, and a magnetic attraction force and a magnetic repulsion force are generated between the rotor magnet and the stator core. Thus, the rotor rotates relative to the stator. [0004] The rotary electric machine generates heat due to operation, and thus is cooled by the cooling medium. For example, cooling medium flow paths are provided inside the rotor from the radially inner side to the radially outer side. For example, the cooling medium temporaril...
