Comparison of Track Topologies of Permanent Magnet Electrodynamic Suspensions
2023 14th International Symposium on Linear Drivers for Industry Applications (LDIA), 2023 High-speed MAGLEV can rely on electrodynamic suspensions for their levitation. The track, the conductive part of the suspension where eddy currents take place, has a great influence on the forces generated in the system. Different track topologies, either discrete or continuous, have been explored so far, but not globally compared.

Topology Optimization of an Alternate Permanent Magnet Electrodynamic Suspension
2023 IEEE Energy Conversion Congress and Exposition (ECCE), 2023 This paper presents the topology optimization of an alternate permanent magnet electrodynamic suspension in a plane parallel to the track, using therefore a semi-analytical 3-D model. This model is based on the superposition of single permanent magnets to compute the magnetic field of more complex structures.
