Abstract: A linear motor comprises a stator, the stator comprising multiple drive coils and an intermediate circuit electrically conductively connected to each drive coil, the intermediate circuit being configured to exchange energy with each drive coil. The drive coils are arranged along the running rail, where at least one slide comprising a magnet acting as a rotor of the linear motor is movably arranged on the running rail. A controller is configured to independently control each drive coil, so that electrical energy is fed from the intermediate circuit into the drive coils, if a measured intermediate circuit voltage is greater or equal to a predetermined intermediate circuit voltage threshold value, where those drive coils are excluded from the feed-in of the electrical energy which are instantaneously being used for driving or braking the at least one slide and/or have a thermal load which exceeds a predetermined thermal load threshold value.

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 is provided for communicating between passive subscribers of a bus system. A first passive subscriber encodes an original static pattern in a first transmit SERDES element and encodes original user data in a time-synchronized manner with the original static pattern in a second transmit SERDES element. The second passive subscriber receives the encoded static pattern and user data, and generates a sampling clock having a first phase offset and a clock synchronous with a transmit-receive clock having a second phase offset, from the encoded static pattern. The second passive subscriber decodes the encoded static pattern using a first receive SERDES element and the encoded user data, using a second receive SERDES element to obtain a receive data word. The first receive SERDES element and the second receive SERDES element are operated based on the sampling clock, and the receive data word is output synchronously with the synchronous clock.

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.

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.
