    摘要:

    为了提高长初级直线感应电动机的效率以节约电能,在实际应用中需要将其初级分段。以分段长初级直线感应电动机为研究对象,采用有限元方法,建立了单段初级高阶非线性数学模型,同时给出了电感和感应电势关于次级位置的参数方程。最后,以ANSOFT电路编辑器模块和Maxwell有限元模块相结合,完成电源主电路和驱动控制电路的设计以及整个系统动态特性的仿真。仿真结果表明,所搭建模型较好的反映了系统的动态过程以及分段供电的可行性。

    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.
