METHOD FOR DRIVING A ROTOR OF A PLANAR DRIVE SYSTEM
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 invention relates to a stator module (10) for the two-dimensional driving of a rotor (200), which comprises a first magnet unit and a second magnet unit, said module comprising a stator unit (100) provided with first stator segments for interacting with drive magnets of the first magnet unit and second stator segments for interacting with drive magnets of the second magnet unit. The individual stator segments are energised respectively independently from the remaining stator segments. The stator unit (100) comprises a first stator sector, a second stator sector, a third stator sector and a fourth stator sector. The first stator segments of the individual stator sectors each extend in a second direction (14) over all of the adjacently arranged second stator segments of the stator sector in question and the second stator segments of the individual stator sectors each extend in a first direction (12) over all of the adjacently arranged first stator segments of the stator sector in question. Extensions of the stator sectors are respectively shorter in the first and second directions than extensions of a magnet arrangement comprising the magnet units.
The invention relates to a stator unit (100) for driving a rotor of an electrical planar drive system, comprising a first and a second stator sector (110, 112), the stator sectors (110, 112) each comprising conductor strips (125) that extend longitudinally in a first direction (12) and are adjacently arranged in a second direction (14) oriented perpendicularly to the first direction (12), for interacting with drive magnets of the rotor. The first stator sector (110) is arranged adjacently to the second stator sector (112) in the first direction (12). The stator unit (100) comprises a contact structure (421) having a first and a second contact unit group (441, 442). The first contact unit group (441) is electroconductively connected to the conductor strips (125) of the first stator sector (110) and the second contact unit group (442) is electroconductively connected to the conductor strips (125) of the second stator sector (112). The contact structure (421) is arranged on inner edges (163, 173) of the first and second stator sectors (110, 112), which are arranged between the first stator sector (110) and the second stator sector (112).
The invention relates to a stator module for electromagnetically driving a motor of a planetary =drive system comprises a connection module, a power module, a stator unit and a sensor module having a position detection unit for detecting a position of the rotor via the stator unit. The sensor module is arranged in a module housing. 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.
