Embodiment approach 1

[0046] Based on attached figure 1 to attach Figure 21 , the stator 3 of the motor 1 according to Embodiment 1 of the present invention will be described.

[0047] The electric motor 1 (corresponding to a rotating electrical machine) in this embodiment is a synchronous motor for driving wheels of a hybrid vehicle, and is mounted between the clutch device 8 connected to the engine 91 and the transmission device 92 . However, the motor 1 is not limited thereto, and can be applied to all motors, such as motors installed in home appliances and motors that drive general industrial machines.

[0048] In addition, the rotation axis direction or axial direction in the description, unless otherwise specified, all represent the direction along the rotation axis C of the electric motor 1 and the clutch device 8, that is, figure 2 in the left-right direction. In addition, in figure 2 Herein, the left side may be referred to as the front of the electric motor 1 and the clutch device ...

Embodiment approach 2

[0125] Below, based on the attached Figure 22 , with regard to the method of holding the sensor wiring 73 according to the second embodiment, the difference from the first embodiment will be described. Bracket engagement portions 55 (corresponding to connection portions of the present invention) protrude downward from the rear end portions of the two side plates 53 and 54 included in the resin case 5A. When attaching the resin case 5A to the split iron core 41 , the bracket engaging portion 55 is formed to extend from the bottom plate portion 51 (corresponding to the bottom of the present invention) toward the coil 42 . Similar to the first embodiment, the rear end portion of the holder engaging portion 55 is inserted into the locking hole 432 of the bobbin 43 .

[0126] A cutout portion 551 (corresponding to a concave portion in the present invention) is formed on the surface facing the coil 42 of each holder engaging portion 55 . The cutout portion 551 is provided to incl...

Embodiment approach

[0133]The present invention is not limited to the above-described embodiments, and may be modified or expanded as follows.

[0134] The stator of the present invention can be applied to synchronous motors, induction motors, DC motors or all other rotating electrical machines.

[0135] The elastic pieces 58 a , 58 b holding the sensor wiring 73 or the notch 551 may also be formed on the surrounding portion 612 of the slip ring 6 .

[0136] Only one of the oil temperature sensor 7 a and the coil temperature sensor 7 b may be provided on the stator 3 .

[0137] In the storage space TS, only the connection portion between the high-voltage side end 421 of the coil 42 and the power supply terminal 64 and the connection portion between the low-voltage side end 422 of the coil 42 and the neutral point terminal 44 may be accommodated. anyone.

[0138] In addition, on each split iron core 41, only one storage space TS is formed by the resin case 5, and only one storage space TS is for...

Abstract

A stator of a rotating electrical machine is provided, the stator easily holds signal lines from a temperature detecting body on the stator. The stator of the electrical machine fixed in the electrical machine housing includes a core unit which includes plural core assemblies arranged annularly, each core assembly being wound with a coil; a resin box installed on each separating iron core and provided with specified volume, wherein, the resin box receives a connection portion of end portions of adjacent coils for forming a neutral point and a connection portion connecting the high voltage side end portion of the coil and the wire section, a oil temperature detector which detects at least one of a temperature of an oil stored in the electrical machine housing and a coil temperature sensor detecting temperature of the coil are disposed in the iron core unit. A thermal resistance included in the oil temperature detector and the coil temperature sensor is connected with a sensor wiring, and an elastic sheet used for holding the sensor wiring is formed in the resin box.

Description

technical field [0001] The invention relates to a stator of a rotating electrical machine, which drives a rotor. Background technique [0002] Currently, there is a technique related to a stator of a rotating electrical machine provided with a temperature sensor for detecting the temperature of a stator coil (for example, refer to Patent Document 1). In the current technology disclosed in Patent Document 1, a temperature detection portion of a temperature sensor is inserted between adjacent coils, thereby detecting the temperature near the stator coils. [0003] Here, the sensor wiring connected to the temperature detection unit is usually wound around a narrow stator, and then led out to the outside through a connector or the like. Therefore, it must be tightly held on the stator in order to avoid interference with the rotor etc. during deployment. When the rotating electric machine is mounted on a vehicle, if the sensor wiring attached to the stator is loose, there is a ...
