  • Piezo drive
    Patent number: 8664829
    Abstract: The invention relates to a piezo drive, in particular for use in geodesic devices, having at least one piezoelectric motor element that includes an advancing component, a running surface component, and a receptacle for the running surface component, wherein said receptacle is to be connected to a component to be driven, wherein the piezoelectric motor element has a window of operation of the motor as a frequency range of the movement of the advancing component. The running surface component and the receptacle are sized and connected to one another such that the natural resonances of the running surface component lie outside the window of operation of the motor.
