An apparatus and method for identifying the position of a magnetic shaft are provided. N field sensors are adjacently positioned at fixed locations relative to the shaft's periodic field, corresponding to 180/N relative phase shifts. A table provides N>2 predetermined signal models and a pre-identified position associated with each. An interpolator compares a representation of the N measured sensor signals to at least two predetermined models to generate a correction signal that provides another pre-identified position. The correction signal depends on N sensors for every position of the shaft. The correction signal is used to incrementally choose said another pre-identified position from the table as an approximate position of the shaft in an iterative process to find the minimum correction signal and identify the position.

L'invention concerne un appareil et un procédé permettant d'identifier la position d'un arbre magnétique. N capteurs de champ sont positionnés de manière adjacente à des emplacements fixes relativement au champ périodique de l'arbre correspondant aux décalages de phase relative de 180/N. Un tableau fournit N>2 modèles de signaux prédéterminés et une position pré-identifiée associée à chacun. Un interpolateur compare une représentation des N signaux de détection mesurés à au moins deux modèles prédéterminés afin de générer un signal de correction qui représente une autre position pré-identifiée. Le signal de correction dépend de N capteurs pour chaque position de l'arbre. Le signal de correction est utilisé afin de choisir de manière incrémentielle ladite autre position pré-identifiée dans le tableau en tant que position approximative de l'arbre dans un processus itératif pour trouver le signal de correction minimum et identifier la position.
