Air bearing, planar drives are best suited for point-to-point positioning where the precision requirement is in the µm range. With planar motor systems, force is produced via the reluctance principle. Because of the strong magnetic attraction of the forcer on the stator, a planar system can be used vertically as well as overhanging.
A planar system can also make more efficient use of workspace by utilizing more than one forcer per stator. Two or more forcers acting independently on the same stator can more effectively utilize constrained production process space.
