Footpath 1.5mm, deep 20mm hole, the K-type thermocouple is positioned in the hole.
The brush is the brush of 10 passages at a high speed；The K-type thermocouple is the thermocouple with electro-magnetic screen function, can
To prevent interference of the motor internal electromagnetic field to thermocouple signal.
The lead-out terminal of the K-type thermocouple is connected with the brush, i.e., the wire of described K-type thermocouple is connected to brush
Round end do dynamic with transhipment；The round end of the brush can be fixed in the connecting shaft.In the present embodiment, the K-type
The lead-out terminal of thermocouple can be welded on the both positive and negative polarity of brush round end by flatiron.
It will be welded on the thermocouple connecting line of Ω on the both positive and negative polarity of brush stationary end, while the Ω of correspondence different measuring points
Head is inserted on data collecting instrument.
Now, when motor is operated, the data collecting instrument can use 10Hz frequency the millivolt signal of thermocouple
From the stationary end outflow of brush to data collecting instrument, and the 4-20mA electric signals needed.
It can be seen that, a kind of temperature measuring equipment of strong magnetic-type revolving part of the present utility model, by the device to rotor
Temperature carries out continuous accurate acquisition, so as to understand motor rotor temperature distribution situation, preferably provides support for emulation.The device
It is easily achieved, improves the accuracy of simulation model, greatly shorten product development cycle.
For ease of description, the quality of embodiment is not only represented for the sequencing of above example.
Finally it should be noted that：Above example is only to illustrate the technical solution of the utility model, rather than its limitations；
Although the utility model is described in detail with reference to the foregoing embodiments, it will be understood by those within the art that：
It can still modify to the technical scheme described in foregoing embodiments, or which part technical characteristic is carried out etc.
With replacement；And these modifications or replacement, the essence of appropriate technical solution is departed from each embodiment technology of the utility model
