成したことを特徴とする超音波モータ。 A stator of a vertical/torsional composite piezoelectric vibrator, a head mass that transmits vertical/torsional vibration modes, a rotor that rotates in forward and reverse directions in response to vertical/torsional vibrations, and a central shaft that tightens the stator and rotor with the head mass sandwiched therebetween. In an ultrasonic motor consisting of a plurality of discs, each electrode plate is made up of a plurality of current-carrying materials each having a hole in the center thereof, into which a shaft is inserted, and connected in a series with a runner. An ultrasonic motor characterized in that it is configured to be folded in a bellows shape, and a piezoelectric element such as a vertical vibrator or a torsional vibrator is inserted and bonded between the two.
