A magnetic drive system for a door leaf includes a carrying slide for carrying the door leaf; a row of magnets disposed in the driving direction and having a length L and a longitudinal direction, the magnets being arranged so that magnetizations of the magnets reverse at a predetermined interval in the longitudinal direction; a coil arrangement comprising coil cores and coils which are wound around respective coil cores; and a displacement measuring system comprising a first magnetically sensitive position sensor and a second magnetically sensitive position sensor which is separated from the first position sensor by a distance A. The distance A is larger than the difference between the length L and the travel path V and smaller than the length L.
