Abstract

This paper presents a MAGLEV system in which the magnetic suspension is assured by the repulsion of permanent magnets both on the guideway and on the vehicle. Due to the induced currents on a aluminum sheet surrounding the magnets on the guideway, the system intrinsic instability is overcome. The detailed structure of the proposed system is described and the main results of the simulations by means a FE code are reported.
