Abstract
This paper deals with dynamic modeling of a bearingless flux-switching permanent-magnet (FSPM) linear machine. Based on equivalent magnetic models, an analytical model is derived, taking into account airgap variation and magnetic saturation. The effects of these phenomena are analyzed using finite-element method (FEM) simulations of a test motor. The proposed model can be fitted to the FEM data or measured data. The model can be applied in real-time control of a magnetically levitating motor drive as well as in time-domain simulations. Experimental results are used to validate the proposed model.
