In this paper, an analytical model of permanent magnet electrodynamic suspension systems (PEDSs) is proposed. Horizontal and vertical magnetic flelds of a permanent magnet (PM) are efiectively approximated by sinusoidal functions. By this means, closed form solutions are obtained for lift and drag forces of PEDSs for the flrst time. The suspension system is then modelled by flnite element method (FEM). The accuracy of the analytical model is validated by FEM and experimental measurements.
