    • The present invention concerns a piezoelectric motor of the type including: a stator (2); a rotor (20) capable of moving in rotation in a plane (Pdm) called the mean movement plane perpendicular to a geometrical rotational axis (X1) on which the rotor (20) is centred; coupling means (8) for driving the rotor (20) arranged between the stator (2) and said rotor (20); piezoelectric means (12) capable of being electrically excited to impart a vibratory movement onto the coupling means (8); transmission means (40) able to transmit the vibratory movement from the coupling means (8) to the rotor (20) in order to drive said rotor (20) in rotation about its axis (X1), and holding means (44) for applying the rotor (20) onto the coupling means (8), characterised in that the coupling means (8) are arranged freely about the geometrical rotational axis (X1) on which they are centred, and in that the coupling means (8) rest on the stator (2) via support means (10) shaped to convert the vibratory movement of the points (P) in the contact region between the coupling means (8) and the rotor (20) into a substantially elliptical forward or backward movement, essentially perpendicular to the plane of the rotor (20).
