Abstract: 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°, 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°.
