Abstract
A stator module for two-dimensionally driving a rotor having first and second magnet units comprises a stator assembly including first and second stator segments for interacting with drive magnets of the first and second magnet units. The individual stator segments may each be energized independently from the remaining stator segments. The stator assembly comprises 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 comprising the magnet units.
