In a conveyor system, a magnet element row aligned at least partly parallel to the conveyor path is arranged in a driving region to serve as a stationary drive device. Conveyor elements include conducting parts (4) and are movable along the conveyor path through the drive region. The magnet element row (11) includes alternatingly orientated permanent magnets and produces a magnetic field locally changing along the row (11). The conducting parts (4) are arranged on the conveyor elements (2) such that in the drive region they are positioned in the effective range of the magnet element row (11). A relative movement between the magnetic element row (11) and the conveyor element (2) produces eddy currents in the conducting parts (4) effecting forces counteracting the relative movement. The relative movement is produced by annular magnet element rows (11) that are revolvingly driven and of which a part moves parallel to the conveyor path being in interaction with the conducting parts (4) of conveyor elements (2). The drive device works without contact and permits jolt-free conveyance, particularly when used in conjunction with independently movable conveyor elements.
