A transport system may include at least two conveyor sections and at least three cars that are moved individually in a cyclical operation. Each car may pass through a first conveyor section starting from a first start position and subsequently pass through a second conveyor section back to the first start position. At least one stopping point may be provided at least along a conveyor section, and one or more subsequent stopping points may respectively be assigned to a block. Travel of the cars may be controlled such that the cars successively approach a respective previously-specified block, and an equal cycle time is predefined for every car to pass through the first and second conveyor sections. A method for operating a transport system in this manner is also disclosed.

Operating a cyclical transport system based on an equal cycle time

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