The aim of research is the reduction of power consumption of linear induction motor (LIM) for the new electric train drive. For the essential solution, the compensation methods of the characteristic end effect were studied and the following results were obtained.The following two methods are based on our proposed concept.1. As regards the rotating permanent magnets type of compensator, the following was verified experimentally.(1) This compensator can supply the secondary eddy current for compensation of end effect.(2) In the design of this compensator, it is necessary to take into consideration not only the supply eddy current but also the flux path of the compensator - the reaction plate - LIM.2. As regards the static winding type of compensator with two coils, the following was obtained analytically.(1) The drag force can be reduced to less than 0.5kN as against the LIM rated thrust of 12kN by the optimum design of the pole pitch and length of compensator.(2) We developed the analysis for the overall characteristics of LIM and the compensator. The analysis shows that the overall efficiency is higher than the efficiency of LIM alone without end effect under the condition of light compensation. As a concrete value, the efficiency becomes to be about 80% that increases by about 5%. This is a new phenomenon for farther discussion.

研究的目的是降低新型电动列车驱动系统中直线感应电动机（LIM）的功耗。针对本质解，研究了特征端部效应的补偿方法，得到了以下结果：以下两种方法是基于我们提出的概念.关于旋转永磁体类型的补偿器，通过实验验证了以下内容。(1)该补偿器可提供二次涡流补偿端部效应。(2)在这种补偿器的设计中，不仅要考虑供应涡流，而且还要考虑补偿器的磁通路径-反应板- LIM.2。关于具有两个线圈的静态绕组型补偿器，通过分析获得以下结果。(1)通过对补偿器极距和长度的优化设计，使直线电机额定推力12 kN时的牵引力降至0.5kN以下。(2)对直线电机和补偿器的整体特性进行了分析。分析表明，在光补偿条件下，总效率比无端部效应时单独使用直线感应电机的效率高。作为具体值，效率变为约80%，增加约5%。这是一个有待进一步讨论的新现象。
