Abstract:
A stator module for two-dimensionally driving a rotor having first and second magnet units includes a stator assembly with first and second stator segments configured for interacting with drive magnets of the first and second magnet units. The individual stator segments can each be energized independently from the remaining stator segments. The stator assembly includes first, second, third and fourth stator sectors. The first stator segments of the individual stator sectors each extend in a second direction over all second stator segments of the relevant stator sector, arranged side by side, and the second stator segments of the individual stator sectors each extend in a first direction over all first stator segments of the relevant stator sector arranged side by side. Extensions of the stator sectors in the first and second directions are respectively smaller than extensions of a magnet arrangement including the first and second magnet units.
