Abstract
The piezoelectric motor () comprises 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 (H), characterised 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 the advance element () at least temporarily lies on the engagement surface (). The advance element () comprises a first part-section () as well as a second part-section (), wherein the part-sections () have a different resonant frequency.
