  • Patent number: 4453103
    Abstract: The proposed motor comprises a stator and a rotor frictionally interacting with said stator, either said stator and rotor including at least one piezoelectric oscillator. Said oscillator includes a piezoelectric element and electrodes located on the opposite surfaces of the piezoelectric element and connected to a supply source for exciting in this oscillator a resonant mode of longitudinal acoustic vibrations. The motor further includes at least two pushers, each having one end secured on said oscillator and the other end urged against a surface of frictional interaction of the rotor and stator. The piezoelectirc element used in this motor is polarized in the direction perpendicular to the surfaces of the electrodes and is positioned so that the propagation direction of the resonant mode of the longitudinal vibrations is perpedicular to the surface of frictional interaction.
