Abstract:The significance is increasing efficiency and saving energy for segmenting the long primary linear induction motor(LIM) into blocks. As the research object, a high order and non-linear model for single segment primary is built by using the finite element method (FEM), and the equations of inductance and induced electromotive force are established with the position of secondary as a parameter. Then, with the combination of the ANSOFT circuit editor module and the Maxwell finite element module, the main circuit and the driving control circuit are designed. Finally, The system’s dynamic characteristics are simulated and analyzed.by software ANSOFT. The simulation results show that the proposed model can reflect the dynamic process of the system and the feasibility of the segmented feeding well.
