摘要

The present invention relates to a method for correcting a time-dependent measurement signal (M) generated using an electric motor (1.1) coupled with a transmission (1.2) on the driven side with respect to the effect of a variable driven load and a variable number of revolutions. , in these methods: a) tapping the time-varying measurement signal M, which depends on the rotational moment of the motor transmission unit 1, b) generating a useful signal N1 that does not contain a direct current component from the measurement signal; c) intermittently determining valid values from the measurement signal M; d) generating a load-corrected useful signal (N2) by intermittently dividing the useful signal (N1) without a direct current component by the interval-specific effective values; e) time-resolved determination of the rotational frequency f of the motor 1 from the measurement signal M; f) scaling the load-corrected useful signal N2 to the average rotational frequency to produce a calibrated measurement signal M corr , and g) using the calibrated measurement signal for error detection of the motor-transmission unit is carried out. The invention also relates to a method for recognizing wear and/or damage to a motor-transmission unit using a calibration method.
