Abstract
An electric motor for rotating a wheel of a vehicle, the electric motor having a rotor, a stator and coil windings, a first sensor arranged to output a first signal indicative of a position of the rotor relative to the stator, a second sensor arranged to output a second signal indicative of a position of the rotor relative to the stator; wherein the first sensor and second sensor are offset with respect to each other such that upon rotation of the rotor relative to the stator the first output signal and second output signal allow the direction of the rotor to be determined; wherein the first output signal and second output signal are used for controlling current in the coil windings and at least one of the first output signal and second output signal are provided to a vehicle braking system to allow the vehicle braking system to determine a wheel lock condition or an onset of a wheel lock condition, wherein the onset of a wheel lock condition is determined based on predetermined criteria.
