Abstract: The piezoactive actuator with amplified movement comprises a first sub-assembly formed by a mechanical movement amplifier and a second sub-assembly equipped with piezoactive elements. An interface with a load and an interface with a base, respectively placed at the peaks of a small axis of the shell and designed for actuating the load with respect to the base, define an actuating axis. A longitudinal deformation of the large axis enables a deformation of the small axis to be induced, designed to generate a movement at the interface with the load, the component of which movement along the small axis is amplified. At least one zone made of elastomer material is arranged at least substantially along the actuating axis to dampen deformations and increase the capacity of the actuator to resist external stresses. The actuator comprises at least one free space adjacent to the elastomer material zones in a direction orthogonal to the actuating axis.

Abstract: The invention relates to a fine positioning system using an inertial motor based on a mechanical amplifier that comprises a first amplified inertial sub-assembly including a mechanical amplifier, a piezoactive member and a countermass. A second relative drive sub-assembly includes a clamp and a clamped member attached to the first amplified inertial sub-assembly. Asymmetric excitation cycles of the first inertial sub-assembly generate impact forces and movements amplified in a driving direction (z), thus resulting in sliding and adhesion successions of the clamped member in the clamp in order to generate a relative translation movements of the points A and B relative to the point D. The mechanical amplifier increases the step size and reduces the supply inrush currents. Fine and dynamic positioning of the point B relative to the point D can be achieved with augmented strokes using the amplifier.

Abstract: A piezoactive motor has a stator equipped with independent stator modules 44, each comprising at least one pair of longitudinal piezoactive actuators 12, 14 colinearly arranged inside a mechanical coupling element 16 in the form of a shell 20. In addition, it is fixed by flexible decoupling links 68, 70 and comprises a central countermass 18. To produce a closed trajectory of the peaks (A and B) designed to cause by friction relative movement of a driven part over a large travel distance, and to position the driven part, these modules use separately or in combination:translational deformation, obtained when the piezoactive actuators are deformed in opposition and produce a tangential movement of the peaks (A and B) of the shell (20) relatively to the countermass (18), due to the mass ratio between the countermass and the shell,flexional deformation, obtained when the piezoactive actuators are deformed in the same way and produce a flexion of the shell (20), resulting in a normal movement of the peaks A and B.

Abstract: The stator of the motor comprises a support structure bearing at least one pair of transducers each including a vibrating element, the transducers being located colinearly and excited so their vibrating elements vibrate at one and the same frequency, but with a phase shift of 90.degree., and a coupling shell to which the vibrations are applied, and at least one rotor frictionally driven by the coupling shell. The coupling shell is of closed shape and is fixed at two opposed points on its major axis to the transducers. The resonance frequency of the coupling shell is the same in both vibration modes so that high efficiency is obtained.
