This paper presents lightweight optimum design of electromagnet in magnetic levitation system. This paper deals with the possibility of using the response surface methodology (RSM) for optimization of an electromagnet with a higher number of the design variables. 2D and 3D magnetostatic analysis of electromagnet is performed by using ANSYS. The most effective design variables were extracted by pareto chart. The most desired set is determined and the influence of each design variables on the objective function can be obtained. This paper procedure is validated by the comparison between experimental and calculation result.
