<p>The piezoelectric motor, comprising a stator (5) with a toothed ring (6) on a fixed supporting base (18) and a rotor (1) with an annular shoe (2) pressing on the ring, and piezoelectric excitation elements (10), has the fixed base shaped to provide annular support for the ring with forces applied substantially symmetrically in relation to the ring's cylindrical median plane. The base can be made from outer and inner rings located on either side of the stator ring and connected by elastically deformable suspension elements in the form of C- or S-shaped arms.</p> |
