Abstract

A method of condition monitoring an electrical machine (11), the method comprising: a) obtaining a baseline of a monitored parameter of the electrical machine (11) from a machine learning model of the electrical machine (11) based on a set of measurement parameter values from sensors (13) arranged to measure parameters of the electrical machine (11) and on a set of electrical machine parameter values including electric drive configuration parameter values from an electric drive (15) controlling the electrical machine (11), b) obtaining a measurement of the monitored parameter, measured while controlling the electrical machine (11) with the electric drive (15) using the same electric drive configuration parameter values as in step a), c) comparing the measurement of the monitored parameter with the baseline, and d) determining that a fault is present in the electrical machine (11) in case the measurement of the monitored parameter deviates with more than a predetermined amount from the baseline.
