| description | The invention relates to a method and a device for measuring the mechanical angular position of a rotor, comprising, during a calibration phase and subsequently during a setting phase:-acquiring Ns measurement signals at a measurement position, which is offset by a corresponding mechanical angle modulo an angle of 2Pi/Nc radians, for Ns = 2, the measurement position is offset by a Pi/(2 * Nc) radians, and for Ns = 3, the measurement signals are offset by a corresponding mechanical angle modulo an angle of 2Pi/Nc radians; the measuring position deviates by the radian of 2Pi/3Nc; -calculating an instantaneous electrical angular position value taking into account the arc tangent of the ratio of the values of the two measurement signals for the time taken into account, or taking into account the arc tangent of the ratio of the values of the two transformed values obtained by a Clark transformation applied to the three measurement signals; -determining an electrical calibration signature (SIGcb) and an electrical |
