Abstract: This paper presents the design, control and experiments of a magnetic bearing system, of which operation principle is based upon dc magnetic attraction. Initially, electromechanical model is derived for representing dynamics of the system. The magnetic bearing model is formed in virtual environment (VisSim TM) and simulation results have obtained for various improper conditions such as the deviation from balanced condition. Then, design optimization is achieved by using FEM analysis and the results of the simulation is presented. Finally, experimental set up is formed in which digital PD type controller is used for obtaining a stable levitation. It is shown that, the system is levitated stable at standstill.
