Abstract: The authors have proposed new compensation methods for a solution of the end effect of the linear induction motor (LIM), which is to supply the eddy current with minimum power loss in front of LIM. As one of proposed methods, the magnet rotator type compensator is discussed in the paper. The effect is studied analytically on the LIM parameters used in subways in Japan. The thrust density distribution of the LIM with the compensator clearly shows the improvement in the front region. The thrust and the output kW per input kVA of the LIM at the slip of 0.1 increase by 58% and 45% respectively by using the compensator.
