Optimal Design of Magnetic Suspension Using Design of Experiment

실험계획법을 이용한 Magnetic suspension의 최적설계

This paper proposes the design method of a magnetic suspension that can control external vibration caused by low frequencies on the external vibrations by low frequencies. The magnetic suspension with individual controls is able to compensate the vibrations unlike a mechanical suspension. In the magnetic suspension, two characteristics are required. Firstly, magnetic motive force(MMF) by armature winding must be increased linearly. Secondly, identical magnitude of output force should be produced as direction of MMF. In this paper, axis-symmetric finite element analysis is used for magnetic field analysis. In order to optimize magnetic suspension, response surface methodology combined with experimental design is applied to investigate the characteristics and optimize the magnetic suspension for vibration -free table.
