由于长初级双面直线感应电机（DSLIM）和短初级DSLIM之间的运动和边界条件不同，纵向端部效应不同。本文根据基本原理和电磁场理论，分析了长初级LIM的动态纵向端部效应，并解释了这两种DSLIM之间磁场行波的差异及其影响。通过理论分析，给出了考虑端部效应的等效电路模型和修正系数。为了验证模型的有效性，利用Ansoft 3-D进行了3D场分析，并给出了场分布。分析结果与考虑末端效应的结果比不考虑末端效应的结果吻合较好。一个有用的结论是，通过正确选择次级极并适当注意机器运行时的滑差，末端效应的影响将比短初级 DSLIM 中的影响小得多。为今后此类机械的设计和工业应用提供了良好的途径。
Due to the difference of movement and boundary conditions between long-primary double-sided linear induction motors (DSLIMs) and short-primary DSLIMs, the longitudinal end effect is different. This paper analyzes the dynamic longitudinal end effect of long-primary LIMs according to the basic principle and electromagnetic field theory and explains the difference of magnetic field traveling wave and its influence between these two kinds of DSLIM. The equivalent circuit model and correction factors considering the end effect are described through theory analysis. To verify the validity of the model, 3-D field analysis by Ansoft 3-D is implemented, and the field distribution is presented. The analysis results have a good agreement with the results where the end effect is considered than that where the end effect is not considered. A useful conclusion is that, with proper selection of the secondary poles and proper attention to the slip that the machine is operating at, the end effect will have a much smaller influence than that in the short-primary DSLIM. It provides a good way for this kind of machine design and industrial application in the future.
