する超音波モータ。[Claims for Utility Model Registration] (1) A driving high frequency voltage having a phase difference of 90 degrees is applied to two sets of piezoelectric parts bonded to one surface of the stator to generate a traveling wave, and the slider material is In an ultrasonic motor that rotates the rotor by applying a traveling wave generated on the stator to the rotor, a large number of narrow slits are radially provided on the annular surface of the stator on the rotor side. An ultrasonic motor characterized by having a coating material with a small coefficient of friction provided throughout. (2) A driving high-frequency voltage with a 90° phase difference is applied to two sets of piezoelectric parts bonded to one side of the stator to generate a traveling wave, which is generated in the stator on the rotor provided with the slider material. In an ultrasonic motor that uses traveling waves to rotate the rotor, a large number of radial protrusions are provided on the annular surface of the stator on the rotor side, and narrow slits are formed on the top surface of each protrusion in the same direction as the protrusions. 1. An ultrasonic motor, characterized in that a plurality of ridges are provided in the ridge, and a coating material having a small friction coefficient is provided on the upper surface of each ridge having a slit.
