Abstract: In this paper the effect of different parameters like size of actuator and rail, current density, no of turns of coil, permeability of magnetic material, winding dimension etc. has been studied. An FEM analysis of U-I structure of rail (guide-way) and actuator for electromagnetic levitation system has been performed by the utilizing of the ANSYS software. The design of electromagnets is primarily controlled by the input power to lift power ratio and lift power magnet weight ratio. These factors are dependent on the magnet dimensions, required gap flux and hence the required current density in the winding. The magnet configurations chosen on the basis of required pole-face area and necessary window area to house the excitation coils. In this work a FEM based analysis has done to find out the flux pattern, working flux density, field intensity, force etc. for single actuator based levitation system. The changing of different parameters of rail and actuator the flux pattern, working flux density, field intensity and force will change.
