Stator assembly

A stator assembly for driving a rotor of an electrical planar motor, wherein the stator assembly comprises:

• a first arrangement of longitudinal stator layers and a second arrangement of oblique stator layers,
• wherein the longitudinal stator layers comprise first coil conductors and wherein the oblique stator layers comprise second coil conductors,
• wherein the second coil conductors are configured to interact with second drive magnets of the rotor in order to drive the rotor in a first direction,
• wherein the first coil conductors are configured to interact with the first drive magnets of the rotor in order to drive the rotor in a second direction differing from the first direction,
• wherein the longitudinal stator layers and the oblique stator layers are arranged on top of one another in a third direction oriented perpendicularly to the first and second direction, and
• wherein the first arrangement of longitudinal stator layers and the second arrangement of oblique stator layers have a shared central plane and the longitudinal stator layers and the oblique stator layers are each symmetrical in the third direction with regard to the shared central plane.

A planar-drive system having a stator module and a rotor, wherein the stator module comprises:

• a module housing and a stator assembly,
• wherein the stator assembly comprises a first arrangement of longitudinal stator layers and a second arrangement of oblique stator layers,
• wherein the longitudinal stator layers comprise first coil conductors and wherein the oblique stator layers comprise second coil conductors,
• wherein the second coil conductors are configured to interact with second drive magnets of the rotor in order to drive the rotor an a first direction,
• wherein the first coil conductors are configured to interact with first drive magnets of the rotor in order to drive the rotor in a second direction differing from the first direction,
• wherein the longitudinal stator layers and the oblique stator layers are arranged on top of one another in a third direction oriented perpendicularly to the first and second direction,
• wherein the stator assembly being arranged above the module housing at an upper side of the stator module and comprising a planar stator surface on the upper side of the stator module, and
• wherein the rotor is arranged above the stator surface of the stator module in in a floating position over the stator surface.
