Abstract
A handwheel actuator assembly 600 for a steer by wire steering system of a vehicle is disclosed. The assembly 600 comprises a steering wheel 601 and a feedback torque generator. The steering wheel 601 has at least one hand grip portion rotatable around an axis of rotation of the steering wheel 601 which can be gripped by a driver and a hub 602 that supports the hand grip portion. The feedback torque generator comprises an electric motor which has a stator 609 and a rotor 610. The rotor 610 is directly or indirectly fixed to and rotates with the hub of the steering wheel 601 and the stator 609 is secured to a fixed part of the vehicle body such that it cannot rotate relative to the vehicle body. The motor comprises a brushless permanent magnet Vernier motor.
