  • Piezoelectric motor with efficient transfer of energy
    Patent number: 9197141
    Abstract: Provided are embodiments of piezoelectric motors which comprise at least one piezo-electrically active part and one passive part which are mounted with the ability of relative movement with respect to each other and which interact with each other by friction. The piezo-electrically active part includes at least one oscillator of acoustic vibrations with one or more piezoelectric elements in the form of a planar ring with acoustically attached flat pushers made from materials such as steel or ceramic. The flat pushers are pressed to a flat surface of the piezoelectric element, either directly or through an elastic element.
