Latest Patents
Lionel Petit's latest patents include advancements in traveling-wave piezoelectric motors. The first patent describes a traveling wave piezoelectric motor featuring a stator in the form of an annular plate. This stator is connected to two groups of cylindrical polarized ceramic piezoelectric elements, which are excited by an alternating current with a phase shift of 90 degrees. This design generates a deformation in the form of a traveling wave at the surface of the stator, working in conjunction with a rotor in the form of a disk. The piezoelectric elements are connected to the stator via an auxiliary coupling piece, ensuring efficient operation.
The second patent also focuses on a traveling-wave piezoelectric motor, which comprises at least one stator and two groups of piezoelectric elements made of independently polarized ceramic rods. These rods are arranged perpendicularly to the stator and are excited by an alternating current with a phase shift of π/2. This configuration generates a traveling wave on the surface of the stator, which is designed as a wheel with a peripheral annulus. The innovative design allows for greater compression of the rods, enhancing the motor's performance.
