提出了一种新型的直线感应电机端部效应补偿器，该补偿器的基本原理是：在直线感应电机前只提供与直线感应电机频率同步的涡流，就可以补偿端部效应，而不需要根据直线感应电机的转差率来调节涡流的螺距，尽管需要调节电流的相位。在磁转子型和交流线圈型补偿器模型上，理论得到了解析证实。采用恒转速、恒磁动势的方法，虽然方法简单，但通过转子补偿的转差特性是平滑的。静止式交流线圈也可以补偿直线电机的推力，但由于线圈自身的端部效应较大，对直线电机和补偿器总推力的改善并不明显。
The new end effect compensator for a linear induction motor (LIM) is proposed, which is based on the theory that the end effect can be compensated only by supplying the eddy current synchronizing with the LIM frequency in front of LIM without adjusting the pitch of the eddy current with the operating slip of LIM, although the phase adjustment of current is required. The theory is confirmed analytically on the models of the magnet rotator type and the AC coil type compensators. The slip characteristics compensated by the magnet rotator is smooth in spite of the simple method with the constant rotating speed and the constant magnetomotive force (MMF). The static type of AC coil can compensate the thrust of LIM too, but the improvement of total thrust of LIM and the compensator is not so large in this numerical example, because of the large own end effect.
