Abstract: The performance of a passive-levitation vehicle is improved for moving over a path, wherein the vehicle has a levitation skid slidable on the path and capable of developing a levitation force to support a compartment at a certain distance from the path. For this aim, there is a suspension, connected between the compartment and the skid, comprising a kinematic structure to confer degrees of freedom and relative constraints between the skid and the compartment; a passive elastic element connected between the skid and the compartment; and a controlled- dynamic element able to exert a force having controlled dynamics between the skid and the compartment; wherein the passive elastic element and the controlled- dynamic element being mounted in parallel to each other and connected, e.g. at their ends, respectively to the skid and the compartment. By means of a sensor the distance is detected between the skid and the path, and an electronic circuit, connected to the sensor and to the controlled- dynamics element, carries out a feedback control in order to adjust said distance.

Abstract: An improved suspension is described with electromagnetic linear actuator (MC1; MC2; MC3), comprising a stator (10) and a stem (30) which is housed in a linearly sliding manner in the stator (10). The stator (10) comprises an external sleeve (12) made of ferromagnetic material and the windings (26) are consisting only of wires of conducting material insulated from each other and free of ferromagnetic parts.
