Claim 14:
15. Transport system for the transport of loads, comprising:
a synchronous, long-stator linear motor,
a plurality of transport elements, and
a control unit, which is adapted to move the transport elements along a transport conveyor of the transport system in an individually controlled manner by means of the long-stator linear motor
wherein the transport system further comprises a position detection device and/or speed detection device along at least a section of the transport conveyor for detecting a movement profile of a transport element, and
wherein the long-stator linear motor has an integrated measuring device for detecting a temporal course of a load current and/or a load voltage with which the control unit operates the long-stator linear motor;
wherein
the control unit is adapted to drive a variety of individually drivable electromagnets of the long-stator linear motor according to at least one excitation pattern, each excitation pattern corresponding to a movement profile of the transport element, and to determine a loading condition, including a load of the transport element and a wear of a bearing of the transport element on the transport conveyor as a function of a detected movement profile and a detected time profile 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.
