Abstract: A planar drive system comprises a stator and a rotor. The stator comprises a plurality of energizable stator conductors. The rotor comprises a magnet device having at least one rotor magnet. A magnetic interaction can be produced between energized stator conductors of the stator and the magnet device to drive the rotor. The stator is configured to carry out energization of the stator conductors so that an alternating magnetic field can be generated via the energized stator conductors. The rotor comprises at least one rotor coil in which an alternating voltage can be induced due to the alternating magnetic field. The planar drive system is configured to transmit data from the stator to the rotor, and the stator is configured to temporarily influence the energization of the stator conductors in order to temporarily cause a change with respect to the alternating voltage induced in the at least one rotor coil.

Abstract: A method for determining a rotor position of a BLDC motor with a magnetic rotor and stator having at least one exciter coil to which an exciter voltage is applied in accordance with a commutation process, comprises: interrupting the exciter voltage applied to the exciter coil, wherein the exciter voltage has a profile with at least one first section in which the profile of the exciter voltage has a non-vanishing finite gradient, wherein the exciter voltage in the first section is interrupted, and wherein at the time of interruption the exciter voltage has a value different from zero; capturing a voltage induced in the exciter coil by the magnetic rotor; restoring the exciter voltage to a value different from zero; and determining a rotor position of the rotor with respect to the exciter coil on the basis of the captured induced voltage.

Abstract: A planar drive system comprises a stator and a rotor. The stator comprises a plurality of stator conductors. The rotor comprises a magnet device comprising at least one rotor magnet. The stator is configured to energize the stator conductors. A magnetic interaction can be produced between energized stator conductors of the stator and the magnet device of the rotor in order to drive the rotor. The stator is configured to carry out the energizing of the stator conductors by a current control based on a pulse-width modulation. Due to the current control, a ripple current in energized stator conductors of the stator and thereby an alternating magnetic field can be generated. The rotor comprises at least one rotor coil in which an alternating voltage can be induced due to the alternating magnetic field.

Abstract: A modular machine-automation system includes a server module and a plurality of client modules. Each client module includes a housing having a first client module connection face with a first client signal transfer unit and a second client module connection face with a second client signal transfer, and a client bus switch-on unit. In an initialization mode, a client signal coupling unit in the client bus switch-on unit is configured to determine which client module connection face is connected to a server module connection face, either directly or via one or a plurality of further client modules, in order to switch to a first operating mode when the first client module connection face is coupled to the server module connection face, and to a second operating mode when the second client module connection face is coupled to the server module connection face.
