Sliding door comprising a magnetic drive system provided with a path measuring system

A magnetic drive system for driving a door leaf of a sliding door in a driving direction, comprising:

• a carrying slide for carrying the door leaf;
• a row of magnets supported by the carrying slide and disposed in the driving direction, the row of magnets 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 a plurality of coil cores and a plurality of coils which are wound around respective coil cores, the carrying slide being movable relative to the coil arrangement along a travel path V;
• and
• a displacement measuring system cooperating with the row of magnets as a magnetic measuring scale for measuring a position of the carrying slide along the travel path V, the displacement measuring system comprising a first magnetically sensitive position sensor and a second, adjacent magnetically sensitive position sensor which is separated from the first position sensor by a distance A, the adjacent first and second position sensors being separated by at least one of the plurality of coils,
• wherein when energized, the coils interact with the magnets to generate a thrust force for driving the carrying slide in the driving direction along the travel path,
• wherein the distance A is larger than the difference between the length L and the travel path V and smaller than the length L, and
• wherein the first and second position sensors are disposed so that the travel path V is subdivided into two measuring ranges of the first and second position sensors.
