音波モータ。[Claims for Utility Model Registration] Acoustic vibrations of the rotor section caused by ultrasonic vibrations near the resonance point of the stator section on at least one surface of the upper and lower surfaces or side surfaces of the rotor section, which rotates due to traveling waves caused by ultrasonic vibrations of the stator section. An ultrasonic motor characterized in that a ring-shaped damping material is fixed to absorb vibration, and the frequency of a drive signal that generates the traveling wave is brought close to the frequency of the resonance point.
