Abstract
A method for monitoring an electrodynamic machine a stator and a rotor arrangement mounted along a rotatable shaft. The rotor arrangement is disposed within the stator and forms an air gap between the rotor arrangement and the stator. At least one sensor is disposed in the air gap and/or within the stator. Measurement signals are detected that are dependent on a magnetic field produced by the electrodynamic machine. The measurement signals are used as a basis for detecting oscillations of the shaft.
