Abstract

A method and a magnetic levitation vehicle operating with this method are described. For the control of support gaps (10a, 10b) that are formed during operation of the magnetic levitation vehicle (1) between a track (2, 3, 4) and a number of carrying magnets (6a, 6b) fastened to said magnetic levitation vehicle (1) and provided with windings (16a, 16b), wherein at least two carrying magnets (6a, 6b) in adjacent positions act upon a suspension frame (8) of said magnetic levitation vehicle (1), the electrical currents flowing through the windings (16a, 16b) are so controlled that the support gaps (10a, 10b) between these two carrying magnets (6a, 6b) and the track (2, 3, 4) adopt pre-determined nominal values (na, nb). In accordance with the invention and in case that the currents through the windings (16a, 16b) of the adjacent carrying magnets (6a) are different under normal conditions, the nominal values (na, nb) for the support gaps (10a, 10b) are altered such that the current through the windings (16a or 16b) of a carrying magnet (6a, 6b) with the lower electric current is increased and/or the electric current through the winding (16b and/or 16a) of a carrying magnet (6b, 6a) wit…
