The performance of electrodynamic Maglev systems is dominated primarily by the electromagnetic interactions between the onboard superconducting magnets (SCMs) and the normal levitation and propulsion coils situated on the guideway. A variety of vastly different coil configurations have been proposed, resulting in large differences in the performance parameters (velocity, external magnetic field, ride quality, etc.). In this paper, alternative designs will be examined in terms of the resulting SCM-ground coil interactions. In particular, the ‘Modified Null Flux’ configuration [1] and the ladder-on-box-beam approach [2] are compared. Magnetic drag, levitation and guidance forces are considered on an absolute and per (kg/m) of ground coil basis.
