Abstract: A method and an apparatus are described for monitoring the wear of a long stator linear motor system comprising at least one motor train with stators and at least one transport vehicle that is driven electromagnetically thereby. Due to the fact that a force exerted electromagnetically and/or mechanically upon said motor train by the transport vehicle transverse to the latter's direction of transport or a differential force exerted in such manner by the transport vehicle upon two oppositely disposed motor trains is measured using sensors, changes in the forces between the motor train and the vehicle caused by dimensional tolerances and/or wear can be detected in order to prevent a malfunction of the track switch.

Abstract: A switch of a transport system for a movable transport element includes a main track and a secondary track branching off the main track. The movable transport element can be guided from a transition region in which the secondary track branches off from the main track. Devices for increasing a switching force to guide a moveable transport element along the main track or transfer the movable transport element to the secondary track are provided in the transition region.

Abstract: The present invention provides a method for identifying a load and/or wear of a transport element of a transport system with a long-stator linear motor, comprising the steps of: exciting a dynamic system consisting of the long-stator linear motor (160) and the transport element according to at least one excitation pattern; detecting the movement profile of the transport element on the basis of the at least one excitation pattern; and detecting a temporal course of a load current and/or of a load voltage of the long-stator linear motor according to the at least one excitation pattern by means of an integrated measuring device of the long-stator linear motor; wherein a loading condition of the transport element is determined depending on the detected movement profile and the detected temporal course of the load current and/or of the load voltage.

Abstract: The invention relates to a switch (1) of a transport system for a movable transport element (T), where the switch (1) comprises a main track (3) and a secondary track (4) branching off, where the movable transport element (T) can be guided from a transition region (2), in which the secondary track (4) branches off from the main track (3), optionally along the main track (3) or transferred into the secondary track (4), where one or more linear motor sections (5a, 5b, 5c, 5d) are respectively provided at the main track (3) and the secondary track (4) for moving the movable transport element (T), where a normal force is present between the movable transport element (T) and the adjacent linear motor section or the adjacent linear motor sections (5a, 5b, 5c, 5d), characterized in that devices for altering the normal force are provided in the transition region. The invention also relates to a transport system comprising such a switch and a transport element for such a transport system.
