“…The SERVOSTAR 601...620 series servo motor used in the motion mechanism has been determined to cause electromagnetic interference to the thermocouple temperature measurement system after testing and analysis. According to the above simulation model for electromagnetic interference suppression, and according to the analysis of the actual situation in the thermal test process of the solar simulator, for this kind of differential mode interference, EMI should be suppressed from the coupling path [9] , eliminating high-frequency signals by adding a π-type filter to the output section of the driver cable. Since the π-type filter has a large insertion loss for high-frequency signals, it does not affect the current of the normal operating frequency of the motor while suppressing the transmission of high-frequency signals [10] .…”

The thermal test temperature acquisition system is one of the core systems in the thermal test of the spacecraft. It uses thermocouple sensors for temperature data acquisition, and its data stability directly affects the success or failure of the thermal test task. The equipment types in the original thermal test environment were single, and the electromagnetic compatibility design was weak. With the increase of the types of test equipment in the thermal test, the electromagnetic interference in the test environment is becoming more and more serious and even directly affects the stability of temperature data collection. Based on the principle of thermocouple temperature measurement and electromagnetic compatibility, this paper establishes relevant models for analysis and simulation and obtains methods to improve system electromagnetic compatibility under different interference conditions. And in a certain thermal test, using the simulation results of the model, the corresponding circuit improvement was carried out, which finally reduced the influence of electromagnetic interference on the system and ensured the smooth progress of the task.

“…The number of power lines and position sensor lines grows as more PMSMs are operated, which results in complicated wiring. Thus, the power lines and sensor lines should be reduced 1–3 . Position sensor lines include power lines and signal lines, and the number of sensor lines can be reduced by combining power lines with signal lines.…”

Permanent magnet synchronous motors (PMSM) are very popular in the industrial market. Recently, robots are installed to compensate for the shortage of labor. Due to the increase in motors, the number of power lines and position sensor cable wiring are increased; this increase in complicated wiring is a problem. As a method to solve these problems, power superimposition technology in the power line of a PMSM is expected to reduce the distribution cables. In this paper, the power superposition technology method, and circuit equations of mounting transformers in power lines are presented and are then verified by experiment, simulation, and linear analysis. The circuit equation is proposed as a three‐phase circuit equation, which is transformed into a dq‐circuit equation by a transformation matrix. The characteristics of the electric angular frequency versus the dq‐axis voltage demonstrated satisfactory results, with errors within 1% in linear analysis and simulation. The linear analysis and experiment are shown to be similar, although there are some errors. The validity of the circuit equations could be demonstrated by the verification results.
