This paper discusses the applications of dynamic circuit theory to ele
ctrodynamic suspension EDS systems. In particular, the paper focuses o
n the loop-shaped coil and the figure-eight-shaped null-flux coil susp
ension systems. Mathematical models, including very general force expr
essions that can be used for the development of computer codes, are pr
ovided for each of these suspension systems. General applications and
advantages of the dynamic circuit model are summarized. The paper emph
asizes the transient and dynamic analysis and computer simulation of m
aglev systems. In general, the method discussed here can be applied to
many EDS maglev design concepts. It is also suited for the computatio
n of the performance of maglev propulsion systems. Numerical examples
are presented in the paper to demonstrate the capability of the model.
