Abstract: A novel sandwiched maglev positioning stage is proposed in this paper. Mathematical model and finite element models are made up to analyze levitation force and driving force on maglev stage in two different structures—ordinary and sandwiched, which can verify the better performance of sandwiched structure. Also, the analysis of the relation between current input and working forces help a lot to the control of the maglev stage.
