摘要： A method for driving at least one rotor in a planar drive system. The rotor has a device for generating a magnetic field. The rotor can be moved on a drive surface formed by stator modules comprising a magnetic field generator. A virtual two-dimensional potential curve is determined for the rotor, with a target point having an attractive potential. A virtual force vector is determined with a vector direction and a vector length at a first position of the rotor, which is determined from the virtual two-dimensional potential curve. A magnetic drive field interacting with the magnetic field of the rotor is generated by the magnetic field generator such that a resulting force is applied to the rotor by interaction of the magnetic drive field with the magnetic field. The direction of the resulting force is based on the vector direction, and the strength is based on the vector length.

摘要： A method for preventing collisions when driving at least two movers on a drive surface, each mover comprising at least one magnetic field generator, with a device comprising a plurality of plate-shaped sectors, the sectors each comprising at least one electric magnetic field generator. The sectors form the drive surface, generating magnetic fields via control of a power supply of the electric magnetic field generators such that the movers are movable over the drive surface in at least one direction. A first path planning for the first mover is carried out, an estimated second travel path of the second mover is determined or received, and the estimated second travel path of the second mover is taken into account in the first path planning of the first mover to determine a first travel path for the first mover such that collision of the first mover with the second mover is prevented.

摘要： A device and method for preventing a collision when determining travel paths for at least two movers on a drive surface, each mover comprising at least a second magnetic field generator, the device comprising a plurality of sectors, the sectors comprising magnetic field generators for generating magnetic fields, the sectors forming the drive surface. A path planning for at least two movers is carried out, at least the two movers being assigned a priority, the priorities of the movers being taken into account in the path planning such that a path of a mover is assigned a priority in the path planning of the travel paths of the movers, and a travel path of a mover with a higher priority takes precedence over a travel path of a mover with a lower priority, so that a collision of the movers is prevented.
