AB  - 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 alternance of magnetic poles. Through the optimization of the lift-to-drag ratio and the mass of the suspension, it is shown that both configurations can have similar performances. The Halbach array has a lower overall mass but a higher permanent magnet volume and therefore cost. A portion of the additional weight of the alternate arrangement can be gained by reducing its back-iron thickness and removing materials at the center of the magnetic poles.
