Abstract
The disclosure discloses a magnetic levitation planar motor workbench having a double-layer winding of coarse and fine drive, which belongs to the technical field of planar motors, and includes a stator and a mover. The vertically magnetized permanent magnets and the horizontally magnetized permanent magnets in the stator are arranged in a Halbach arrangement; the mover is located on the enhanced side of the air gap magnetic field above the stator. The mover adopts the double-layer winding of unequal heights, and the height of the upper first winding is smaller than the lower second winding. Each layer of winding may generate driving forces in six directions to achieve six-degree-of-freedom driving.
