[0027] The stator end of the slip ring 2 is inserted into the mounting adapter 13, which is connected to the mounting bracket 1 through the mounting adapter 13. The rotor end of the slip ring 2 is fixedly connected to the winding reel 4 through the slip ring pin 8.

[0034] To avoid magnetizing the frame of the equipment under test, stainless steel is used. This material has many advantages, including good casting performance, no tendency to thermal cracking, good airtightness, low linear shrinkage, high strength, corrosion resistance, and good machinability. While stainless steel is cost-effective in reducing wear and damage during long-term use, it minimizes the impact on test quality, ensures the equipment's robustness and durability, and extends its service life.

[0035] Furthermore, the coaxiality of the bearing 404, coupling locking shaft 405, slip ring wire winding column 403, and flange 402 of the winding disc 4 is ≤Φ0.008mm, and the perpendicularity of the shaft shoulder is ≤Φ0.01mm.

[0036] By ensuring the positional accuracy of the motor mounting hole 105, bearing mounting hole 102, optical shaft mounting hole 103, and slip ring mounting hole 101, the straightness of the linear optical shaft 3, the rotational coaxiality of the winding disc 4, the coaxiality of the bearing 404, coupling locking shaft 405, slip ring wire winding column 403, and flange 402, and the perpendicularity of the shaft shoulder, the error after installation is reduced and the accuracy is improved.

[0037] Improving its installation accuracy ensures that the coaxiality between the tooling and the product being tested is ≤ Φ0.02mm. Simultaneously, this structure effectively prevents displacement caused by centrifugal force generated during high-speed rotation of the slip ring 2.

[0038] Working principle:

[0039] During the test, the stator end of the conductive slip ring 2 is fixed to the mounting bracket 1, and the rotor end of the slip ring 2 is fixed to the winding disc 4.
