Cross magnetization effect on inductances of linear synchronous reluctance motor under load conditions

The paper deals with the Finite Element Method (FEM) based procedure for determination of operating point dependent inductances of a Linear Synchronous Reluctance Motor (LSRM). Special attention is paid to the effects of cross magnetization and saturation on the inductances of LSRM under load conditions. To achieve a deeper insight into the cross magnetization and the saturation phenomena a standard two-axis LSRM dynamic model is modified. The modified dynamic LSRM model contains explicit terms for the direct and the quadrature axis self-inductances and explicit terms for the cross coupling inductances. The last ones appear as a consequence of the cross coupling between the direct and the quadrature axis. All inductances of the modified LSRM model are current dependent.
