This article deals with the characteristic analysis of electrodynamic suspension (EDS) device with the permanent magnet (PM) Halbach array system. On the basis of transfer relation theorem with magnetic vector potential, the magnetic field quantities were obtained and then confirmed with the corresponding two-dimensional and three-dimensional finite element analysis result. In order to validate the characteristic analysis scheme for PM-EDS device, the dynamic performance was tested by using a high-speed rotary-type dynamic test facility with linear peripheral speed up to 250 km/h. A comparison is made between the analysis and the experimental results to demonstrate the design considerations of PM-EDS device for high-speed maglev. (C) 2009 American Institute of Physics.
