This thesis dissertation focuses on the design of a limited angle torque motor able to drive and control a spool valve of a fully active suspension system for automotive applications. Such a system can work as passive and semi-active dampers, absorbing and dissipating energy from the interaction between road and vehicle, but it is also able to introduce energy in the equation above. This allow the car to achieve greater results in terms of both handling and comfort. An example of handling improvement is the reduction and eventually the elimination of the roll rotation of the chassis of the vehicle during the various stages of a curve, while, regarding the comfort, in case of bump or hole in the path of a wheel, this system could actively pull up or push down the hub of the wheel, smoothing the effect of a change in the road to body of the automobile.
