Abstract (en)
[origin: CA3193757A1] The invention relates to a method for monitoring one or more electric drives (M1, M2, M3, M4) of an electromechanical system, in particular of a wind direction tracking system of a wind turbine, wherein the one or more drives (M1, M2, M3, M4) act upon a movable machine component of the installation, for example upon a bearing ring (2) of an azimuth bearing (1). The method is characterized in that: during operation of the drives, a plurality of currents, for example phase currents of multiple phases (L1, L2, L3), and/or of multiple drives (M1, M2, M3, M4), are measured at a predefined sampling rate and stored as a measured value series each containing a predefined number m of measured values; statistical characteristic values are in each case calculated from one or more measured value series; and one or more items of state information and/or state forecasts is/are generated for one or more drives by analysing the variation over time of the characteristic values and/or by analysing a correlation of the characteristic values of different motor currents.
