Abstract The present invention provides a method for driving at least one rotor (200) on a drive surface formed by means of stator modules. A virtual two-dimensional potential curve (300) is first determined for the rotor (200), with a target point (260) of the rotor (200) having an attractive potential within the virtual two-dimensional potential curve (300). Next, a virtual force vector (250) is determined at a first position (252) of the rotor (200), which is determined from the virtual two-dimensional potential curve (300). Subse- quently, a magnetic drive field interacting with the magnetic field of the rotor (200) is generated in such a way that a resulting force is applied to the rotor (200) by the interac- tion of the magnetic drive field with the magnetic field.

The stator unit and the power module are arranged on an upper side of the module housing, and the connection module is arranged on an underside of the module housing, opposite the upper side. A power generating unit of the power module and the connection module are connected via a drive energy line. To design the direct drive energy line with a high degree of conductivity and a small resistive loss, the drive energy line leading through the module housing is insulated electrically from the sensor module in the module housing.
