Abstract

The vertical levitation force, guidance force and magnetic stiffness values and thus the loading capacity and movement stability of high temperature superconducting (HTS) Maglev systems are aimed to be increased in this study by using auxiliary permanent magnets (PMs) in the onboard unit together with the multi-surface HTS-permanent magnetic guideway (PMG) arrangement (hybrid multi-surface arrangement). Firstly, the magnetic levitation force, guidance force and stiffness performances of hybrid multi-surface arrangement were investigated in different field cooling heights (FCH). Then, to compensate for the negation of instability results from the higher repulsive force between the onboard PMs and the PMG, and to obtain optimum magnetic field medium, we have changed the vertical position of the auxiliary onboard PMs (Z PM ) as Z PM =0 mm, 2 mm, and 4 mm, at the cost of a bit decrement in the vertical levitation force. Obtained bigger levitation force together with the guidance force values, in FCH=25 mm and for Z PM =0 mm, indicates that the hybrid multi-surface HTS-PMG arrangements are beneficial to increase the practical applicability of Maglev systems.
