英文摘要	A linear induction motor system composed of a high-T. superconducting secondary with close-ended coils made of REBCO coated conductor wire was designed and tested experimentally. The measured thrust, normal force and power loss are presented and explained by combining the flux dynamics inside superconductors with existing linear drive theory. It is found that an inherent capacitive component associated to the flux motion of vortices in the Type-II superconductor reduces the impedance of the coils; from such, the associated Lorentz forces are drastically increased. The resulting breakout thrust of the designed linear motor system was found to be extremely high (up to 4.7 kN/m(2)) while the associated normal forces only a fraction of the thrust. Compared to its conventional counterparts, high-T. superconducting secondaries appear to be more feasible for use in maglev propulsion and electromagnetic launchers.
