Rotor position sensor system for detecting rotary angular position of rotor shaft of servo motor of steering system of motor vehicle, has magnetic rings with magnet or soft magnetic part, and magnetic field sensors attached to each ring

摘要

The system (8) has a magnet and/or a soft magnetic part or magnetic field sensors (11, 12) connected with a rotor shaft (15) of an electric drive motor or a shaft driven by the rotor shaft in a torque proof manner. The magnet and/or soft magnetic part or magnetic field sensors are fixedly arranged at the motor housing and/or a component connected with the motor housing. Two parallel magnetic rings (9, 10) are provided with the magnet or the soft magnetic part, and the magnetic field sensors are attached to each magnetic ring.
