Abstract
A steer-by-wire system comprising a steering wheel for use by an operator and an electric motor assembly coupled to the steering wheel for providing active torque feedback. The electric motor has a rotor mounted for rotation, and a magnet mounted to the rotor for rotation about an axis, wherein the at least one magnet is a permanent magnet with a pole pair. A fixed stator has coils for creating an electric field to act upon the magnet. Electronics are positioned on the axis of the magnet for controlling commutation of the stator coils and generating a primary high resolution angular position signal indicative of movement of the steering wheel by the operator. High resolution on-axis sensors, in communication with the electronics, detect a commutation position between the rotor and the stator and producing first and second continuous angle measurements for the pole pair of the at least one magnet.
