A piezoelectric motor of the invention comprises a stator and a rotor one of which includes at least one first piezoelectric oscillator. The rotor consists of a first and a second parts one of which parts includes a second piezoelectric oscillator. Said parts of the rotor are mounted for relative rotation about the axis of rotation. The first part is in contact with the stator along the first surface of frictional interaction and with the second part along the second surface of frictional interaction. Each surface of frictional interaction is formed by rotation of at least one straight line length about the axis of rotation of the rotor.
A piezoelectric motor comprising a stator and a rotor one of which includes at least one first piezoelectric oscillator including a piezoelectric element having a working surface, the rotor consisting of a first and a second parts, one of which parts including at least one second piezoelectric oscillator having a piezoelectric element having a working surface, said first and second parts of the rotor being capable of mutually rotating with respect to the axis of rotation of the rotor, said first part of the rotor being in contact with the stator on the first surface of the frictional interaction provided by rotation of at least one length of a straight line about the axis of rotation of the rotor and with said second part of said rotor on a second surface of frictional interaction provided by rotation of at least one length of a straight line about the axis of rotation of said rotor.
