Abstract
In accordance with an exemplary embodiment, an active suspension system having a regenerative actuator is provided for an electric or hybrid electric vehicle. The system comprises a drive system including a battery mounted to a chassis and a controller coupled to the drive system. The controller also couples to a suspension system between the chassis and at least one wheel of the vehicle. The suspension system includes an actuator having an electric motor providing energy by converting linear movement of a ball screw into rotational movement of a rotor having a hollow core permitting at least a portion of the ball screw to translate within the rotor during operation of the actuator.
