  • Inductive rotation sensor with improved accuracy
    Patent number: 10352730
    Abstract: The invention relates to a rotation sensor, comprising: —a stator (A) and rotor (B), arranged coaxially and forming a magnetic circuit (10, 20), the rotor being mounted angularly displaced with respect to the stator, —a primary winding, suitable for generating a magnetic field in the magnetic circuit, and —at least one secondary winding, characterized in that the magnetic circuit comprises at least one tooth (220) extending radially with respect to the axis (X-X) of the stator and of the rotor, and at least one notch (12) suitable for receiving said tooth, such that the tooth is separated from the notch by at least one tangential air gap (51) that is variable according to the angular displacement of the rotor with respect to the stator, the tooth and the notch being shaped so that, during a rotation of the rotor with respect to the stator, a variation in the width of the tangential air gap causes an increase or a decrease in the permeance of the air and, respectively, an increase or a decrease in the voltage
