Abstract: A drive module for a linear transport system comprises a housing and a stator, wherein a conveying device of the linear transport system with a magnet arrangement can be arranged on the housing. The stator is arranged in the housing, wherein the stator comprises at least one coil arrangement having at least one coil with at least one stator tooth. The coil arrangement is designed to switchably provide a magnetic traveling field, wherein the magnetic traveling field exits from the coil arrangement at the end faces and passes through the housing shells in order to enter into operative connection with the magnet arrangement of the conveying device of the linear transport system on the outer side of the housing for the purpose of forming a magnetic coupling.

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: An inductive energy-transmitting device is provided in a linear transport system in which at least one magnetically driven carriage moves along a carriage guide including a motor module device. The inductive energy-transmitting device includes an energy-transmitting coil having a primary winding for applying an input voltage and an energy-receiving coil having a secondary winding for tapping an output voltage. The secondary winding of the energy-receiving coil has a control-voltage-winding portion and a load-voltage-winding portion, the control-voltage-winding portion and the load-voltage-winding portion including winding conductor tracks separate from each other. In this context, the control-voltage-winding portion provides a control voltage for tapping by a carriage guide controller on the carriage, and the load-voltage-winding portion provides a load voltage for tapping by a load on the carriage

Abstract: A method for transferring data between movable and stationary units of a linear transport system having a controller and linear motor with stator and rotor for driving the movable unit along a guide rail. The stator includes the stationary units, each with one or more drive coils. The rotor is arranged on the movable unit, with one or more magnets. The stationary units each have at least one stationary antenna, and the movable unit has a movable antenna. The controller selects a stationary antenna based on position data of the moveable antenna and outputs a data packet to the stationary unit, with control and data signals transmitted via the selected stationary antenna. The control signal includes identification information to identify the stationary antenna. The data signal includes a communication frame with a start bit and user data following a start sequence arranged to trigger data receipt of the movable unit.

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.

Abstract: A method for transmitting energy from a stationary unit of a linear transport system to a movable unit of the linear transport system. The linear transport system includes a movable unit and at least one further movable unit, a guide rail and a linear motor. The movable units include energy-transmitting coils. The following steps are carried out by a controller: determining that the movable unit requires an amount of energy to carry out an application that cannot be provided via energy transmission between energy-transmitting coils of at least one stationary unit to the at least one energy-receiving coil, and outputting control signals to at least one stationary unit for positioning the further movable unit in a transmission position on the guide rail immediately in front of or behind the movable unit, and for coupling energy-transmitting elements of the further movable unit to energy-transmitting elements of the movable unit.

Abstract: 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.
