Abstract: Electric circuit for estimating the angular position of a rotor of an electric motor, including: a sensing module configured to receive at least one electric signal representative of a drive current of the electric motor and to generate a measurement signal indicative of a switching of the at least one electric signal and a switching index indicative of the type of switching, rising or falling, of the at least one electric signal; and a computing module configured to supply, from the measurement signal and switching index a position signal representative of an angular position of the electric motor rotor.
