Patent ID: 7105987

Claim:
A piezoelectric motor comprising a stator and a runner which form a gap, as well as comprising a piezoelectric transducer which is connected to the stator or the runner and which with the stator or the runner forms a resonator, wherein the resonator may be excited in a main oscillation direction, characterized in that the stator comprises an engagement surface facing the runner, or the runner an engagement surface which faces the stator, and that the stator or the runner comprises an elastic advance element which bridges the gap between the stator and the runner in a manner such that a tip of the advance element at least temporarily lies on the engagement surface and said advance element comprises a first part-section as well as a second part-section, the first part-section being connected to the stator or the runner, the second part-section being connected to the first part-section at a bend of the advance element, and the second part-section ending with the tip of the advance element, wherein the part-sections have a different resonant frequency.
