Abstract

This paper proposes a new magnetic levitation scheme which is able to generate levitation force for all speeds including standstill. Auxiliary wheels, which are needed in the EDS MAGLEV vehicle, can be eliminated. This scheme uses AC superconducting magnets to generate levitation force. In this paper, magnetic fields, forces and power dissipations generated by DC and AC magnets moving above a conducting slab are calculated analytically. Results show that the characteristics of the EDS system with an AC magnet, such as levitation force and loss, are superior to those using DC magnets for all speeds
