摘要：

The new end effect compensator for 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 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 competed by the magnet rotator is smooth in spite of simple method with the constant rotating speed and the constant magnetomotive force NW. 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.
