Abstract: A linear transport system comprises a first carriage and a second carriage, a linear motor for driving the first carriage and the second carriage and a guide rail. The linear motor comprises a stator and a first and a second rotor. The stator has a plurality of drive coils that are arranged along the guide rail individual motor modules comprise a plurality of drive coils. The first rotor is arranged on the first carriage and the second rotor is arranged on the second carriage. The first carriage has a first magnetic field generator. The second carriage has a second magnetic field generator. The first magnetic field generator differs from the second magnetic field generator at least in terms of its magnetic vector field, wherein the magnetic fields of the magnetic field generators are detected to identify the corresponding carriage.

Abstract: A stator assembly for a planar electrical motor includes coil conductors arranged in a stator layer, elongated in a first direction and arranged side by side in a second direction perpendicular to the first direction. The coil conductors are connected to form a three-phase system, with a first forward conductor and first return conductor of the first phase connected in series to the first forward conductor, a second forward conductor and second return conductor of the second phase connected in series with the second forward conductor, and a third forward conductor and third return conductor of the third phase connected in series with the third forward conductor. The three-phase system has first and second opposite sides. The first forward conductor and the first return conductor are electroconductively connected in series by first and second horizontal connecting conductors arranged in the stator layer on the second and first side, respectively.

Abstract: A method for moving a rotor in a planar drive system having a first and second stator modules and a rotor. The stator modules are arranged at a distance, forming a gap. First and second magnetic fields are generated by the first and stator modules. The first and second magnetic fields hold the rotor in a vertical position, at a distance from a surface of the first and/or second stator module. The first and/or second magnetic fields have a first magnetic field strength to maintain the rotor in the vertical position, and may be used to change a horizontal position of the rotor. The first stator module has a first close range adjacent the gap, where the first magnetic field has a second field strength when the rotor is moved across the gap, greater than the first magnetic field strength.

Abstract: A stator assembly for driving a rotor of a planar electrical motor includes longitudinal stator layers with first coil conductors and inclined stator layers with second coil conductors. The first coil conductors extend in an elongated manner in a first direction, and the second coil conductors extend in an elongated manner in a second direction, different from the first direction. The longitudinal and inclined stator layers are arranged on top of one another in a third direction, oriented perpendicularly to the first and second direction. An uppermost and lowermost stator layer of the stator assembly are each formed as a longitudinal stator layer with first coil conductors. The longitudinal stator layers are arranged in the third direction at most on one side next to an inclined stator layer, and the inclined stator layers are arranged in the third direction at most on one side next to a longitudinal stator layer.

Abstract: A bus system comprises a data line having a first channel with a first pair of wires and a second channel with a second pair of wires. The first channel connects a physical feed module interface to a physical consumer module interface and a first DC voltage source to a first consumer module DC voltage consumer, to transmit a first differential data signal between the feed module interface and the consumer module interface and a first direct current from the first DC voltage source to the first consumer module DC voltage consumer. The second channel connects the feed module interface to the consumer module interface and a second DC voltage source to a second consumer module DC voltage consumer, to transmit a second differential data signal between the feed module interface and the consumer module interface and a second direct current from the second DC voltage source to the second consumer module DC voltage consumer.

Abstract: An industrial robot comprises a modular robot arm having a plurality of arm modules, where a rotation transfer device for optical signal transmission is provided in an arm module or between a first and a second arm module. The rotation transfer device comprises an optomechanical rotation interface having a first interface side and a second interface side, which face each other and are substantially rotationally symmetrical and complementary. The first and second interface sides are configured to rotate relative to each other. The first and second interface sides are mechanically mounted with respect to each other, with a radial plain bearing on one interface side and a slide bearing shell complementary thereto on the other interface side. A gap is formed between the first and second interface sides, in the axial direction of the rotation transfer device, across which the optical signal transmission takes place.

Abstract: This application provides a method for controlling a planar drive system, where the planar drive system comprises at least a controller, a stator module having a stator surface, and a rotor that may is positionable and movable on the stator surface. The method comprises positioning an object on a rotor in a first arrangement state of the object in a positioning step, carrying out an accelerating movement of a defined movement pattern of the rotor; and, by the accelerating movement, arranging the object positioned on the rotor in the first arrangement state in a second arrangement state relative to the rotor, in an arranging step. The application further provides a planar drive system.

Abstract: An assembly of stator modules for a planar drive system comprises a first stator module and a second stator module, The first stator module and/or the second stator module each comprise stator segments with a segment width, the stator segments being energizable, where the stator segments can provide a magnetic field in order to interact with the magnet arrangements of a rotor for driving and/or holding the rotor of the planar drive system. The first stator module and the second stator module are arranged spaced apart from each other and thereby form a gap, where the gap has a gap width, and where the gap width is smaller than or equal to the segment width.
