Abstract：Thesegmented long primary double-sided linear induction motor (LP-DSLIM) system is composed of several segments of unit motors powered in series or in parallel. To accurately describe the state change of unit motor and the transient process when passing through segments during secondary motion, a new mathematical model of unit motor and a segmented LP-DSLIM system model are proposed in this paper. Firstly, the characteristics of the segmented LP-DSLIM system are analyzed. By introducing the virtual secondary board, the secondary coupling of each unit motor is extended to the same length as the primary, so that the primary and secondary of the unit motor are always fully coupled. Then, the actual secondary flux linkage and primary flux linkage are obtained by combining with the coupling factor. The new unit motor mathematical model is derived, and the segmented LP-DSLIM system model is established. Finally, the proposed new unit motor mathematic model and segmented LP-DSLIM system model are verified by FEM calculation and experiments.
