Due to the advantages of no active control, self-stability, large clearance, and small self-weight, the electrodynamic suspension (EDS) system has a wide range of applications in high-speed fields such as ultrahigh speed maglev transportation, electromagnetic ejection, and rocket propulsion. The null-flux coil EDS system, as one of the typical representatives of EDS systems, has attracted the attention of researchers from all over the world and is expected to be commercially applied in Japan in 2027. The calculation method for the mathematical model of the null-flux coil EDS system has been studied by many researchers and some effective conclusions have been obtained. However, due to the complex structure and large number of parameters of the null-flux coil EDS system, most of the existing calculation methods have complex equations and often have some assumptions and premises. This article aims to derive the high-precision numerical and analytical calculation methods for the mathematical model of the null-flux coil EDS system without any excessive simplification or assumption, and to summarize the characteristics of the two methods. To get a further experimental verification, an EDS test system was built, and the high consistency between the test results and the theoretical calculation results proves the correctness of the two calculation methods proposed in this article, which paves a way for further analysis of the null-flux coil EDS system in the future.
