A steer-by-wire steering system for a motor vehicle may include a steering wheel and a feedback actuator connected to the steering wheel for providing road feedback to a driver. The feedback actuator may include an electric motor and an electronic control unit. The feedback actuator may further include at least two redundant rotor position sensors. The electronic control unit may be equipped with sleep-mode functionality, which in case an ignition is off awakens the at least two redundant rotor position sensors periodically or upon movement of a rotor of the electric motor to detect and measure rotation of the rotor.
