Numerical Calculations of Flux-Canceling Maglev with DC & AC excited SCMs

Abstract

The paper shows a numerical calculation feature and the levitation characteristics of a flux-canceling Maglev with AC excitation, which has an array of conducting coils on the ground and two arrays of onboard magnets. In numerical calculations, the guideway coils are approximated as ladder coils. First the necessary number of guideway coils to be considered in numerical calculations is indicated. Then the calculated results confirm that AC excitation realize a levitation capacity at zero vehicle velocity, and its dependence on the vertical position of the onboard magnets and the excitation frequency.
