Dynamic two-axis model of a linear synchronous reluctance motor based on current and position-dependent characteristics of flux linkages

Abstract

This paper analyses the impact of armature slotting and magnetically nonlinear and anisotropic iron core on the trajectories of a kinematically controlled linear synchronous reluctance motor (LSRM). A new magnetically nonlinear dynamic two-axis LSRM model is introduced in order to perform the analysis. The magnetic nonlinearities and slotting effects are accounted for by the current and position-dependent characteristics of flux linkages.
