超音波圧電モータ。 A vertical torsional ultrasonic wave is produced by sandwiching a piezoelectric element exhibiting longitudinal vibration and a piezoelectric element exhibiting torsional vibration between a pair of metal blocks, and making the entire length a half-wave length that resonates in each primary mode of longitudinal vibration and torsional vibration. In a device that uses a vibrator as a stator, a large-diameter support plate is inserted between the longitudinally vibrating piezoelectric element corresponding to the vibration node of the primary resonance mode and the opposing surfaces of the screw and the vibrating piezoelectric element, and the supporting plate An ultrasonic piezoelectric motor, characterized in that the ultrasonic vibrator (stator) is held by the ultrasonic piezoelectric motor.
