摘要:
The invention relates to an ultrasound linear piezoelectric motor comprising an ultrasound oscillator (1) embodied in the form of a piezoelectric plate (4) or a cylinder shell part (3), acoustic oscillation generators (5) and a friction element (6) which frictionally interacts with a driven element (8) and is disposed in a holder. The inventive holder is embodied in the form of an elastic clamp (13) which embraces a driven element, is fixed to the ultrasound oscillator and made of a sound-conducting material.
