Özet

Abstract In implemented studies before, although some advancements have been achieved in improving on the levitation or guidance force efficiency of YBCOs separately, both of these forces could not been enhanced simultaneously. In our study, we investigated levitation, guidance force and magnetic stiffness properties of multi-seeded YBCO bulk depending on different position of onboard PM in different CHs above a Halbach PMG to obtain larger vertical load capability, stability and relating stiffness values at the same time. The levitation, guidance force and relating stiffness measurements were carried out between multi-seeded YBCO and Halbach PMG depending on the onboard PM positions and cooling heights after the magnetic flux distributions modelling of Halbach PMG with onboard PMs. In this paper, it has clearly seen that the levitation force and the vertical magnetic stiffness values increase in optimal onboard PM position, with negligible lose in guidance force and lateral magnetic stiffness values. It is inferred from this study that reasonable position of the onboard PM according to PMG, the cooling conditions and compatibility of YBCO-PMG arrangement in point of magnetic flux distribution are key parameters for efficiency of the load, guidance force and relating magnetic stiffness of Maglev systems. The results obtained in this study have a potential on improvement of HTS Maglev system electromagnetic force capability. © 2015 Elsevier B.V.
