Abstract: A stator arrangement for an electromagnetic linear drive may include a plurality of stator coils that are arranged along a longitudinal direction of a stator. The stator arrangement may also include a plurality of converters that are configured, in each case, to supply at least one first stator coil and a second stator coil of the stator coils with electrical energy. Between the first stator coil and the second stator coil, at least one third stator coil of the stator coils is arranged, which is supplied by a different converter from the first stator coil and the second stator coil.

Abstract: A method for determining a stator current vector for starting a synchronous machine of a drive of a passenger transportation apparatus having a rotor and a stator with a stator winding may involve imposing different stator current vectors with different stator current vector directions on the stator winding over the course of a plurality of current application operations, determining from the different stator current vectors a minimum stator current vector with a minimum stator current vector direction at which a minimum driving torque acting on the rotor is generated in the synchronous machine, determining a starting stator current vector with a starting stator current vector direction from the minimum stator current vector, and imposing the starting stator current vector on the stator winding for starting the synchronous machine.

Abstract: An example electromotive linear drive mechanism for moving walkways for conveying people or objects may comprise a long stator as an active primary part positioned along a direction of movement of a moving walkway, as well as a plurality of passive secondary parts that are movable with respect to the active primary part and are arranged with one another along the direction of movement. The long stator may have a plurality of successive long stator sections in the form of coil groups along the direction of movement. Each long stator section may have its own control device that is configured to move the secondary parts using control parameters stipulated for the respective long stator section. Further, example methods for operating the electromotive linear drive mechanism may involve predefining different movement profiles for the respective control devices for at least some of the long stator sections such that the secondary parts move along the long stator in a non-uniform manner.

Abstract: A magnetic polar arrangement which is intended for magnetic levitation vehicles is described, the magnetic polar arrangement having at least one magnetic pole (22) with a core (6) which defines a magnetic pole surface (23), and with a winding (5) which is set back with respect to the magnetic pole surface (23) in order to form a free space (24). The magnetic pole (22) is provided with a sensor which contains a sensor head (9a), which is arranged at least partially in the free space (24), and an electronic module (9b). According to the invention the sensor head (9a) is physically separated from the electronic module (9b) and is combined, at least with the core (6), to form a single-piece structural unit which is surrounded by a common anti-corrosion layer (26).
