Energy transmission in a linear transport system

A stationary unit of a linear transport system, wherein the stationary unit comprises:

• a stator having one or a plurality of drive coils for driving a rotor, and
• at least one energy-transmitting coil;
• wherein the stationary unit is configured to:
• receive a control signal comprising identification information for identifying at least one of the energy-transmitting coils, and energy quantity information comprising an amount of energy to be transferred,
• select one or a plurality of the at least one energy-transmitting coils of the stationary unit based on the identification information, and
• adjust an energy transfer of the one or plurality of energy-transmitting coils based on the energy quantity information.

A method for transferring energy from a stationary unit of a linear transport system to a movable unit of the linear transport system,

• wherein the linear transport system comprises:
• a guide rail for guiding the movable unit,
• a plurality of stationary units, and
• a linear motor for driving the movable unit along the guide rail;
• wherein the linear motor comprises a stator and a rotor;
• wherein the stator comprises the stationary units, each comprising one or a plurality of drive coils,
• wherein the rotor is arranged on the movable unit and comprises one or a plurality of magnets,
• wherein the stationary units each comprise one or a plurality of energy-transmitting coils,
• wherein the movable unit comprises at least one energy-receiving coil, and
• wherein the linear transport system comprises a controller;
• wherein the following steps are carried out by the controller:
• determining position data of the energy-receiving coil of the movable unit;
• selecting at least one energy-transmitting coil within the linear transport system based on position data from the energy-receiving coil;
• and
• outputting a control signal to the stationary unit comprising the at least one energy-transmitting coil;
• wherein the control signal comprises energy quantity information,
• wherein the energy quantity information comprises an energy amount to be transmitted, wherein the energy amount comprises a load energy quantity at a first point in time and an idle energy quantity at a second point in time,
• wherein the load energy quantity is sufficient to operate a tool arranged on the movable unit, and
• wherein the idle energy quantity is sufficient to maintain a power supply to a communication unit of the movable unit.
