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.
