Abstract

A system for providing driving torque to wheels on a vehicle includes an electric motor having the capability of independently driving rotatable axle shafts. One example includes a single stator with a first armature associated with a first axle shaft and a second armature associated with a second axle shaft. A controller independently controls power to the armatures to achieve the desired wheel speed or driving torque at each of the wheels.
