A position sensor system for detecting an absolute angular position of a
rotor axle of an electric motor at a predetermined angular resolution W.
The position sensor system include, a first Hall sensor device having a
first sensor magnet set-up, set up on the rotor axle, and two first Hall
sensors, which are set up at an angular offset with respect to the rotor
axle so as to achieve a position angle resolution of 90.degree., and
having a second sensor magnet set-up, set up on rotor axle, having n pole
pairs and a number m of second Hall sensors, which are set up at an
angular offset to one another with respect to the rotor axle, the set-up
and the number n of pole pairs and the set-up and the number m of the
second Hall sensors being selected so as clearly to detect angular
segments at the predetermined angular resolution W within the angular
range of the angular offset of 90.degree..
