Device and method for damping unwanted forces in an electrodynamic linear motor and linear electrodynamic motor comprising such a device

The device (10) comprises: - interface screws (11, 12) fixed to the engine (1) and a base (5); - measuring means (21, 22) for measuring noise efforts to generate first signals; - actuators (31) arranged for transmitting, to each screw interface (11, 12), a direction of force opposed to the parasitic force; - a control unit adapted to receive the first signals and for outputting the second signals to the actuators (31) so that each actuator (31) generates a force.
