Abstract
In this paper, a permanent magnet (PM) electrodynamic suspension (EDS) system with a novel Halbach array is presented, to overcome the uncontrol of the levitation force in the PM EDS system. The novel Halbach array consists by winding normal conductor coils on permanent magnets surface. The 2-D analytical expression of the space static magnetic field is calculated using Biot-savart law and surface current method. When the vehicle-mounted novel Halbach array moves to cut the conductive plate, the space magnetic field equations are obtained by establishing equations of magnetic vector potentials using complex Fourier transform of space static magnetic field. The levitation force and drag force are derived using Maxwell stress tensor method. And a 2-D finite-element model is built to validate the accuracy of this proposed analytical model. Furthermore, the effects of the main characteristic parameters on the levitation force are analysed.
