Performance Advances of HTS Maglev Vehicle System in Three Essential Aspects

In order to put the practice of high temperature superconducting (HTS) Maglev vehicle technology into people´s life, the interaction between high temperature superconductor (HTSC) and permanent magnet guideway (PMG) as the basic model of HTS Maglev vehicle was carefully investigated and enhanced from three essential aspects, i.e., bulk HTSC material, PMG field and bulk HTSC magnetization. The maglev experiments were performed with three kinds of bulk HTSC materials, two kinds of PMGs and two kinds of magnetization methods. It is found that three aspects are all very effective to improve the levitation capability and lateral stability. With better bulk material, more reasonable PMG configuration and magnetization method, the performance of HTS Maglev vehicle system will be greatly advanced and closer to an economical and practical level.
