摘要：
High precision electromagnetic calibration force source is one of the important components of micro-thrust measurement system. For obtaining the electromagnetic calibration force with excellent performance，numerical simulation and experimental research methods are used to analyse the influence of geometry sizes of the permanent magnet on the characteristics of electromagnetic force with the relative position of coil and magnet：For the magnet with larger diameter and smaller thickness，the electromagnetic forces have extreme value with the change of relative position，and the electromagnetic forces near the extreme point have high stability and consistency. In addition，according to the variation trend of electromagnetic force，a high-precision setting scheme of the fiducial position （the location of extreme point） of coil and permanent magnet is proposed. And the variation coefficient of electromagnetic force near the fiducial position is about 0.00252. Finally，the large-diameter magnet and coil combined electromagnetic force generation device is determined，and the high-precision electromagnetic force control relationship with a standard error of estimate 0.0137 is established based on the fitting method. © 2022 Journal of Propulsion Technology.
