<p>The drive has a fixed subassembly (2) and a movable subassembly (1) moved in a vertical direction (Z). The movable subassembly has a magnetic yoke (3) with a coil (4). The fixed subassembly has another magnetic yoke (5) with a magnet (6) aligned to the coil. A horizontal gap between the magnetic yokes in a region of the magnet is varied in the vertical direction such that reluctance force (R) between the subassemblies acts in a working area of the drive. The reluctance force counteracts weight force (G) of the subassemblies.</p> |
