Abstract
A planar drive system includes a stator module and a rotor. The stator module has a stator assembly with at least one coil arrangement that can be energized to generate a stator magnetic field above a stator surface, and a magnetic field sensor. The rotor has a magnet arrangement and can be moved above the stator surface via interaction between the stator magnetic field the magnet arrangement. The rotor can be used as an input device or output device, or both. A controller can compare the position of the rotor magnetic field detected with the sensor to the position expected based on energization of the coil arrangement, to determine any deviation of the expected position as an external movement, and to recognize an input thereby. The controller can control an output via a predetermined movement of the rotor, and to energize the coil arrangement so the rotor moves as defined.
