MODELLING AND ANALYSIS OF PERMANENT MAGNET ELECTRODYNAMIC SUSPENSION SYSTEMS [PDF]
Progress In Electromagnetics Research M, 2014 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.
