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.
