Modelling and Analysis of Permanent Magnet Electrodynamic Suspension Systems

In this paper, an analytical model of permanent magnet electrodynamic suspension systems (PEDSs) is proposed. Horizontal and vertical magnetic fields of a permanent magnet (PM) are affectively approximated by sinusoidal functions. By this means, closed form solutions are obtained for lift and drag forces of PEDS for the first time. The suspension system is modelled by finite element method (FEM). The analytical values of lift and drag forces are compared with the FEM results. Also, the analytical results are evaluated by experimental results. As so, the accuracy of the analytical model is validated by FEM and experimental measurements.
