Abstract (en)
[origin: WO2016098032A1] Method for evaluating operating parameters of a synchronous machine (12) comprising, on the one hand, a stator, configured to generate an electromagnetic field rotating with respect to said stator, and, on the other hand, a rotor so that the rotating electromagnetic field drives the rotor round, said evaluating method comprising, for a measurement cycle N, the following steps: - reception of the value of first and second components (la, Ip) of intensity and of first and second components (Va, Vβ) of voltage of a current applied to said stator; - determination of the value of first and second components (ea, ep) of a back-electromotive force, associated with said rotating electromagnetic field, on the basis of said components of intensity and of voltage; - comparison of the value of the first and second components (ea, ep) of the back-electromotive force with the value of the first and second components (ea, ep) of the back-electromotive force of the measurement cycle N-1; - determination of an estimated value of the speed of the rotor(Ωest).
