CAPTEUR MAGNÉTIQUE SANS CONTACT DE POSITION ABSOLUE MULTITOUR À ARBRE TRAVERSANT
摘要:
The invention relates to an absolute position magnetic sensor for measuring the angular position, on a theta course, of a shaft passing through said sensor and comprising at least two systems for detecting the position of the shaft. Said invention is characterised in that: at least one of the detection systems generates a signal according to a "periodical" function of the theta/n period giving the periodical angular position of said shaft; at least one of the detection systems generates an absolute signal on a theta course of the shaft; and theta and n fit the equation: * theta/n = 360 * n > 1.
