Summary:A method for monitoring an electromagnetic actuator type apparatus, the apparatus comprising a three-phase electric motor, the monitoring method comprising the steps of: performing measurements of thethree-phase currents which supply the three-phase electric motor; projecting the three-phase current measurements (Iq) into a Park frame of reference; implementing, on the current in quadrature, a set-theoretic empirical modal decomposition method (30) coupled with a blind source separation method (40), in order to obtain source components (IC, IC10); automatically selecting, from among the source components, a first set of source components (IC1,..., IC9) sensitive to a first fault and a second set of source components (IC9) sensitive to a second fault; constructing (60) a first virtual fault signal and a second virtual fault signal; and extracting (70), from the first virtual fault signal, a first set of signatures representing the first fault, and, from a second virtual fault signal, asecond set of signatures
