Investigation of Magnetic Characteristics of the Multi-Surface HTS-PMG Interactions in Maglev System
The magnetic levitation force between a high temperature superconductor (HTS) and permanent magnet (PM) takes place because of interaction of supercurrents in HTS and magnetic field of PM. To improve the using potential of the High Temperature Superconducting Maglev systems (HTS-Maglev) in commercial applications, some technical properties of these systems such as the loading capacity and the movement stability, should be increased while the cost of the permanent magnetic guideway (PMG), in which the superconducting Maglev moves on it, should be decreased.
In this study, firstly, the magneto-static solution in AC/DC Module in COMSOL Multiphysics® was used to determine the optimum magnetic field distribution of different PMG configurations. Secondly H-formulation using the Partial Differential Equation (PDE) Mode in COMSOL Multiphysics® was used to determine trapped magnetic field and current properties inside the HTS under the non-uniform magnetic field.
It was obtained that different PMG configurations have various magnetic field characteristic and this situation has improved the magnetic and supercurrent properties of the HTS in Maglev system.
