Abstract

The invention relates to a method for monitoring an electrodynamic motor comprising a rotor arrangement (11) which is rotatably mounted in a stator (12). According to said method, at least one measuring variable depending on a magnetic field generated by the electrodynamic motor is detected and evaluated in order to analyse mechanical, electrical and/or magnetic properties of the rotor arrangement (11). The invention is characterised in that the at least one measuring variable is detected on or outside a surface of the stator (12), facing away from the rotor arrangement (11), by means of a sensor.
