Claim 0:
1. Method for identifying a load and/or a wear of a transport element of a transport system with a plurality of transport elements, a synchronous, long-stator linear motor and a control unit for individually controlled movement of the transport elements along a transport conveyor of the transport system by means of the long-stator linear motor, comprising:
exciting a dynamic system consisting of the long-stator linear motor and the transport element by controlling the long-stator linear motor by means of the control unit according to at least one excitation pattern, each excitation pattern corresponding to a movement profile of the transport element along the transport conveyor;
detecting the movement profile of the transport element along the transport conveyor on a basis of the at least one excitation pattern by means of a position detection device and/or speed detection device of the dynamic system;
detecting a temporal course of a load current and/or a load voltage, with which the control unit operates 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, including a load of the transport element, and a wear of a bearing of the transport element on the transport conveyor, is determined by means of the control unit depending on a detected movement profile and a detected temporal course of the load current and/or the load voltage, and
the movement profile is a path-time-profile and/or a speed-time-profile of movement of the transport element.
