NON-CONTACT MULTI-TURN ABSOLUTE POSITION MAGNETIC SENSOR COMPRISING A THROUGH-SHAFT
First Claim
1. Absolute position magnetic sensor for measuring the angular position over an excursion theta of a shaft passing through said sensor, and comprising at least two systems for detecting the position of the shaft,wherein:
- at least one of the detection systems includes a mechanical system for continuous movement transformation of which the input shaft is linked to said shaft, aforesaid at least one detection system generating a signal according to a “
periodic”
function of period theta/n yielding the periodic angular position of said shaft;
at least one of the detection systems generates an absolute signal over an excursion theta of aforesaid shaft;
Theta and n verify the relations;
*Theta/n=360*n>

Abstract
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.
