摘要： The invention relates to a linear ultrasound piezoelectric motor comprising a mobile element that is in frictional contact with a plate-like rectangular resonance plate, wherein the frictional surface is embodied by means of at least one of the longitudinal narrow sides of the resonance plate, and electrodes for producing acoustic vibrations which are arranged on the longitudinal wide sides of the resonance plate. According to the invention, the generator for producing acoustic vibrations is asymmetrically arranged in relation to a plane which symmetrically cross-cuts the resonance plate, and comprises two opposing electrodes generating a stationary asymmetrical space wave when excited.
