CPC Classification
A method for detecting torsional vibration behavior of a drive train of an aircraft that is coupled to a permanent magnet synchronous motor as a drive includes at least one triggering of a short circuit in the permanent magnet synchronous motor in an operating state to apply at least one induced mechanical stimulation of the drive train. A torsional vibration response of the drive train to the induced mechanical stimulation is detected by a sensor device. A corresponding device is also provided.
