To realize the economical and high performance drive for urban transit, a linear motor is driven as a high performance expensive motor or a economical secondary sheet type linear induction motor (LIM) with relative poor performance which is in practical application, by changing the reaction rail, not changing the primary on vehicle. First, it is discussed the secondary wound type LIM without end effect. It is revealed that the wound type LIM has much larger secondary leakage reactance than sheet type LIM, and the performance is not good in this use. Second, the linear synchronous motor (LSM) is discussed as a high performance motor. It is cleared that LSM realizes both the short primary and high efficiency with unity power factor even in the practical section length for the field excitation. So, authors propose the combination use of LSM in power running or braking region and sheet type LIM in other region.
