2024 27th International Conference on Electrical Machines and Systems (ICEMS)This paper presents a novel gradient-based topology optimization method for the design of permanent magnet electrodynamic suspensions, using a 3-D hybrid analytical model. It enables the exploration of new magnet configurations, with the aim of improving both the lift-to-weight and lift-to-drag ratio.

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.

A 3-D Hybrid Analytical Model of a Permanent Magnet Electrodynamic Suspension
IEEE Transactions on Energy ConversionThis paper proposes a hybrid analytical model for addressing 3-D quasi-static eddy current problems involving a magnetic field source moving with respect to a bulk conductive material. The proposed model is particularly useful in applications that include ferromagnetic components, such as a permanent magnet electrodynamic suspension.

Modeling, Design and Analysis of a Electrodynamic Levitation System by Considering the Skin Effect [PDF]
Journal of Intelligent Procedures in Electrical Technology, 2016 In this paper, lift and drag forces of permanent-magnet electrodynamic suspension (PMEDS) System have been studied by considering the skin effect. Electrodynamic suspension is based on repulsive force between two magnetic fields with the same polarity ...

Electrodynamic suspensions are well-suited for high-speed maglev systems. This paper optimizes and compares two configurations of permanent magnets of such suspension integrated in a small-scale test vehicle. The first one is the Halbach array, classically used for the high magnetic flux density it generates, whereas the second one is the simpler ...
