Abstract

Capteur de position angulaire (1) d’un rotor (R) rotatif selon un axe (A) relativement à un stator (S), comprenant une cible (C) ferromagnétique, de section transversale sensiblement ovoïde, solidaire en rotation de l’un parmi le rotor (R) ou le stator (S), et un élément sensible comprenant un premier jeu (J1) de bobines (L11, L12, L13, L14) angulairement équiréparties, solidaire en rotation de l’autre parmi le rotor (R) ou le stator (S), les bobines (L11, L12, L13, L14) étant axialement disposées au droit de la cible (C) afin d’être aptes à mesurer une distance à la cible (C) pour en déduire une position angulaire du rotor (R) relativement au stator (S).
