Beschreibung
Zusammenfassung:	A method is disclosed for transmitting energy from a stationary unit to a movable unit of a linear transport system. The linear transport system includes a guide rail, a plurality of stationary units, and a linear motor for driving the movable unit along the guide rail. The linear motor includes a stator and a rotor, the stator including the stationary units, each having one or more drive coils. The rotor is arranged on the movable unit and incudes one or more magnets. The stationary units each have one or more energy-transmitting coils, each energy-transmitting coil including actuation electronics. The movable unit has at least one energy-receiving coil. The actuation electronics carry out the following steps: reading in an energy quantity signal for the energy-transmitting coil concerned, converting the energy quantity signal into a pulse-pause ratio for actuating the energy-transmitting coil, and actuating the energy-transmitting coil based on the pulse-pause ratio.
