Recently in the field of precision positioning device, the contact-free stages are gaining focuses with their outstanding performances by eliminating mechanical frictions. This paper presents the driving algorithm for contact-free linear stage based on switched reluctance principle. The proposed driving algorithm has a similar structure of that of switched reluctance motor but this study has its own originality in terms of reducing the normal farces and force ripple at the same time. The simulation and experiment are executed to verify the proposed algorithm.
