Beschreibung
Zusammenfassung:	A monitoring device for a reluctance machine includes a vector rotator for rotating a space phasor of the reluctance machine that depends on a voltage in a coordinate system that rotates with a negative fundamental frequency, a low-pass filter filtering the rotated space phasor and producing an output signal, and a signal evaluation device evaluating the output signal. A DC value of the produced output signal in the rotating coordinate system is monitored, and an error in operating the reluctance machine is identified when the DC value is above a predefined threshold value.
