Abstract
Permanent magnet guideway (PMG) has commonly been used for HTS maglev system so far. In some previous studies, electromagnetic guideway (EMG) was proved to have some advantages in practical HTS maglev construction.EMGs with different geometries produce different magnetic field distributions and have different operation performances in HTS maglev system. In this study, comparative experiments of E-shaped and Fan-shaped EMG prototypes have been conducted under the same condition of vertical direction component of magnetic flux density (Bz), power consumption (P), and total magnetic potential (F). The experimental results were compared and discussed, and a 2D finite element simulation model was used to explain and analyze the experimental phenomenon more deeply under condition of the same F. These results may be helpful for further development of EMG for HTS maglev applications and explaining the regularities of levitation and guidance force in principle.
