ことを特徴とする超音波モータ。 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, and the rotor is pressed against the other side of the stator using a spring material. In an ultrasonic motor in which the rotor is rotated by a traveling wave of the stator, an outer annular portion of the rotor that contacts the stator is cut out at appropriate pitches, and a portion that does not contact the stator is provided in the outer annular portion of the rotor. An ultrasonic motor featuring:
