Abstract
A position sensor, in particular, intended for detecting the torsion of a steering column, includes a first magnetized rotor structure comprising magnets, a second stator structure comprising two rings extended by teeth that are axially oriented and interlocked, and a third stationary collector structure including two flux collection parts that define at least one air gap in which at least one magnet-sensitive element is placed. The flux collection parts and the ring gears define a magnetic permeance independent of the relative radial and angular position of the second stator structure with respect to the third collector structure. The collection parts comprise an angular collection sector and a primary collection zone continued by a prolongation having a secondary collection zone. The secondary collection zones end in flat extensions forming two poles of the air gap. The transverse median plane of the air gap intersects at least one of the prolongations.
