Abstract: An improved electrodynamic suspension guidance system for a moving vehicle in which primary conductor loops or magnet coils are mounted to a vehicle in rows parallel to the travel direction, with pairs of magnet coils disposed horizontally one above the other to form a zero flux system with a secondary conductor loop or conductor plate or rail disposed along the road bed, in which the magnet field generated by the upper magnet coil in at least some of the pairs is stronger than the magnetic field generated by the corresponding lower magnet coil of the pair in order to obtain a symmetrical position of the magnet coils with respect to the conductor plate thereby compensating for vehicle weight such that the suspension height tolerances are not decreased.

Abstract: Contactless suspension and guidance of a vehicle using a plurality of primary magnet loops in the vehicle arranged parallel to each other which react with secondary conductors on the roadbed is obtained by providing two vertically arranged primary conductor loops on the vehicle which cooperate with a stabilizing secondary conductor loop disposed between them to form a zero flux system for lateral guidance with a secondary conductor for suspension arranged perpendicular to the vertical conductor loops and below the stabilizing secondary conductor loop to form a normal flux system for suspension, whereby because of the mutual spatial relationship of the two primary conductor loops separate loops for the normal flux system are not required.

Abstract: An improved magnet system for use in electrodynamic vehicle suspension and guidance systems in which a vehicle moves along a track maintained in the suspended condition through the use of a plurality of magnets attached to the vehicle and arranged one behind the other in the direction of travel, the vehicle magnets cooperating with the means on the roadbed to generate the necessary forces to maintain suspension, in which means are provided to change the polarity of two respective adjacent magnets as a function of vehicle velocity and to control the spacing of said adjacent magnet in order to reduce braking losses particularly at high vehicle velocities.
