Abstract — The levitation force and braking force of an electrodynamic maglev system consisting of a linear Halbach array and a conductor plate track are both generated by the interaction between the eddy current generated by the conductor plate and the magnet when the magnet moves. In this paper, using both analytical method and finite element analysis method, a two-dimensional model is established to analyze the dynamic physical characteristics of the electromagnetic field. The two-dimensional model is optimized with the maximum suspension force as the objective, and the optimal values of the important physical parameters in the two-dimensional model are obtained.
