Coordinate by the way of centralized winding outlet, this mode directly limit the detection to stator winding temperature.
The temperature highest part of machine winding is poor in winding overhang, winding overhang radiating condition；Currently for pure electronic
The distributed winding outlet form of motor, is that temperature sensor is directly embedded in into winding overhang, to realize to stator winding
Temperature detection, but this structure type is difficult to for centralized winding outlet method.
In the prior art, it is to use manual type by TEMP for the stator winding of centralized winding outlet method
The problem of device is embedded in the slot for winding of machine winding, then with rope banding fixed, and it is present includes：First, the temperature in slot for winding
Degree be less than with winding overhang temperature, but this mode can not directly detect obtain winding overhang temperature；Second, rope colligation
Form cannot be guaranteed the reliable contacts between sensor and tested surface, unstability in the case of vibrations especially be present；
Propose in Application No. CN2013101038514 Patent Application Publication and passed out winding temperature using heat transfer
Come, detected for the temperature passed out using thermocouple, but detection integrity problem be present in the detection temperature through heat transfer, and
There is error because of heat transmission belt.
Utility model content
The utility model is to avoid the deficiency present in above-mentioned prior art, there is provided a kind of hybrid powder motor stator around
Group temperature measurement structure, realizes the reliable detection for hybrid powder motor stator winding temperature.
The utility model adopts the following technical scheme that to solve technical problem：
The characteristics of the utility model hybrid powder motor stator winding temperature measurement structure is：
Temperature sensor is set, and the temperature sensor is to be pressed with survey using afterbody elastic component in the inner chamber of socket

Cap through hole is opened up on the cap of the hybrid powder motor, the socket of the temperature sensor is through cap through hole
It is inserted in electric machine casing, the socket is fixed on cap, and the temperature probe for making to protrude out utilizes tail springs
Pretightning force contradict in the end of stator winding, realize the temperature detection to stator winding end.
The characteristics of the utility model hybrid powder motor stator winding temperature measurement structure, lies also in：
Seal groove is set in the neck of the socket, the embedded sealing ring in the seal groove, existed using sealing ring
Sealing is formed between cap through hole and socket.
The elastic component is spring.
End cap is set in the afterbody of the socket, the spring base of tail springs is formed with the end cap.
In the socket and end cap to be threadedly coupled.
Compared with the prior art, the utility model has the beneficial effect that：
1st, the utility model is detected directly against winding overhang, and testing result is accurate；
2nd, the utility model is realized reliable between temperature probe and tested surface using the pretightning force of afterbody elastic component
Contact, drastically increase the stability of detection process；
3rd, the utility model is simple in construction, integrated level is high, is easily assembled.

Embodiment
Referring to Fig. 1 and Fig. 2, the form of hybrid powder motor stator winding temperature measurement structure is in the present embodiment：
Temperature sensor is set, and temperature sensor is to be pressed with thermometric using afterbody elastic component in the inner chamber of socket 9
Probe 4, makes the front end of temperature probe 4 be protruded out from the front aperture of socket 9.
Cap through hole is opened up on the cap 5 of hybrid powder motor, the socket 9 of temperature sensor is inserted in through cap through hole
In electric machine casing, socket 9 is set to be fixed on cap 5, and the temperature probe 4 for making to protrude out utilizes the pre- of afterbody elastic component
Clamp force is contradicted in the end of stator winding, realizes the temperature detection to stator winding end.
In specific implementation, seal groove is set in the neck of socket 9, embedded sealing ring 8 in seal groove, utilizes sealing
Circle 8 forms sealing between cap through hole and socket 9；Elastic component uses spring 10, is connected through a screw thread in the afterbody of socket 9
