Abstract (en)
[origin: WO2022084017A1] Device (100) for determining the angular position of a rotor (4) of a rotating electric machine on the basis of signals delivered by a plurality of position sensors (20), this device comprising: - a circuit (103) producing a control loop to estimate the position of the rotor and delivering, as output, a signal representative of the position of the rotor, and - at least one dynamic circuit (102) for processing an odd order harmonic of a signal resulting from the signals provided by the position sensors (20).
