Abstract
The invention relates to a position sensor which is intended, in particular, for detecting a steering column torsion. The invention consists of: a first magnetic rotor structure () comprising a plurality of radially-oriented magnets; a second stator structure comprising two rings () which extend into axially-oriented overlapping teeth (); and a third fixed collector structure () comprising two flux-closing parts which define at least one air gap in which at least one magneto-sensitive element is placed. The invention is characterized in that the flux-closing parts and the stator rings () define therebetween a constant collection surface that is independent of the relative radial position of the two structures.
