TFLIM(Transverse Flux Linear Induction Motor), making its closed magnetic path with the direction of the traveling field orthogonal, had been developed to decrease an edge effect of the general induction motor. To control the levitation force and the thrust force on the secondary part of TFLIM independently, the various methodologies have been presented. When we try to achieve the independent control using only the multi-phase inputs assigned in the stator coils as an approach, in which condition we can minimize the coupling effect between two forces\ulcorner In this paper, we show the qualitative influence of a slip frequency, an ac magnitude, a dc offset superposed in the ac power, and a major parameter of TFLIM on the couple through the computer simulation. And to realize the independent motions between levitation and thrust motion without any auxiliary means fur isolation of the secondary part of TFLIM, the decouple compensator is suggested, including the experimental results.

Superconducting tape easily can applied to distribution of electricity. It designs basic model of Saturable Reactor type Fault Current Limiter which used superconducting tape, and observes a specific character by means of simulation. Saturable Reactor type Fault Current Limiter is not influenced by saturation of Magnet core appeared in Induction Fault Current Limiter, because it exploit saturation of Iron core. But, it is possible that superconducting tape quenched when AC current flow to superconducting tape which biased DC voltage.
