Abstract

IEEEIn the present study, we have designed and constructed a new multisurface HTS Maglev measurement system to investigate the enhancement of magnetic force properties of Maglev systems via multisurface HTS configurations above conventional PMG. We have investigated both the static force and stiffness behavior and dynamic response characteristics of these multisurface HTSPMG arrangements in different field cooling heights (FCH). Optimum cooling height is determined as FCH 2030 for both 6 HTS and 4 HTS configurations. The maximum levitation force values of HTSPMG arrangement with 6 HTS were obtained bigger than that of 4 HTS in the unit cryostat volume of multisurface arrangement, indicating that the HTSs at the bottom side of the cryostat make contribution to the loading capacity of Maglev systems. In the present study, it is observed that the magnetic flux density of bottom surface in addition to upper surface of the PMG can make a contribution to loading performance, vertical and lateral stability of Maglev systems. It is thought that the designed measurement facility and results of this study will be beneficial to increase the magnetic flux density in the unit volume via multisurface HTSPMG arrangements for future design and construction of the HTS Maglev systems.
