Abstract: A switch-on unit for a tool of a movable unit of a linear transport system can be fastened to the movable unit. The switch-on unit includes a housing, an energy-receiving coil with energy-receiving electronics, and a movable antenna with communication electronics. The energy-receiving electronics and the communication electronics are disposed on at least a first circuit board within the housing. The housing has an opening for connections of the tool and an installation space for application electronics. A first circuit board has a first interface for the application electronics, with a power supply and communication link. The communication electronics are arranged to receive a first data signal via the movable antenna, to calculate a second data signal from information about a data structure of the first data signal and the first data signal, and to provide the second data signal at the communication link.

Abstract: A method is provided for transferring energy from a stationary unit to a movable unit of a linear transport system. The system includes a guide rail for guiding the movable unit, a plurality of stationary units, a controller, and a linear motor for driving the movable unit along the guide rail. The linear motor includes a stator and a rotor. The stator comprises the stationary units, each having one or more drive coils. The rotor is arranged on the movable unit, and has one or a more magnets. In addition, the stationary units each have one or more energy-transmitting coils, and the movable unit has at least one energy-receiving coil. The controller determines position data for the energy-receiving coil, selects at least one energy-transmitting coil based on the position data, and outputs a control signal to the stationary unit, with identification information for identifying the energy-transmitting coil.

Abstract: A linear transport system includes a movable carriage, a guide rail for guiding the carriage, and a linear motor for driving the carriage along the guide rail. A system is provided for contactless power and data transmission; e.g., where power and data are each sent inductively via separate coils to the carriage of the linear transport system and/or received by the carriage of a linear transport system. A method of operating such a linear transport system and a contactless power and data transmission system are also included.

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.
