摘要:
为实现高速铁路列车突破600 km/h 的速度极限, 本文提出了一种与现有轮轨交通兼容的高温超导同步直线电机方案, 并通过有限元方法建立了高温超导同步直线电机的仿真模型. 设计并制作了小型实验样机, 其定子由三相铜绕组与硅钢材质的铁轭构成, 使用二代高温超导材料 YBCO 带材绕制车载磁体. 通过实验方法验证了模型的有效性, 并用该模型研究了高温超导线圈回路电流、 线圈匝数和气隙对电机推进力和法向力等电磁力特性的影响规律.本文的研究结果为高温超导同步直线电机在轮轨交通领域中的应用提供了可行性依据.

Abstract:
A high temperature super conducting (HTS) linear synchronous motor (LSM) that could be used in the traction system of high speed railway was demonstrated in our laboratory in order to break through the speed of 600 km/h. The stator was made of three-phase copper windings with a silicon steel yoke, and the mover was constructed by YBCO-coated conductor. Based on a finite-element model which was validated by experiments, we investigated the dependence of the thrust and normal force on the loop current magnetizing the superconducting coil, the number of turns of the superconducting coils and also the gap between the mover and the stator. This work indicates the potential of using the HTS LSM in the traction system of high speed railway.
Key words:  high temperature superconducting ( HTS ) magnet  linear synchronous motor ( LSM )  railway transportation  electromagnetic force
