摘要： With the invention, both a longitudinal vibration mode and a flexural vibration mode are independently detected, or only the longitudinal vibration mode is detected, without using a special device. The invention provides an ultrasonic motor including electromechanical transducers for driving, electromechanical transducers for vibration detection, and an ultrasonic vibrator in which, by supplying two-phase alternating voltages with a predetermined phase difference and predetermined driving frequency to the electromechanical transducers for driving, two different vibration modes are simultaneously generated to produce a substantially elliptical vibration at an output. It is possible to independently detect both the longitudinal vibration mode and the flexural vibration mode with the electromechanical transducers for vibration detection.

摘要： An ultrasonic motor, which rotates a rotor by elastic movement generated by simultaneously exciting vertical oscillation and twisted oscillation in an ultrasonic oscillator, by using expanding and contracting oscillations of a multilayer piezoelectric element formed by laminating two kinds of piezoelectric sheet, is configured as follows. Namely, the multilayer piezoelectric element is formed by alternately laminating a first piezoelectric sheet and a second piezoelectric sheet. The first piezoelectric sheet is provided with a first internal electrode, which is divided into two or more parts, and each divided part is exposed to a peripheral edge of the piezoelectric sheet. The second piezoelectric sheet is provided with an internal electrode, which has a polarity reverse to the first internal electrode, and is divided into two or more parts, and each divided part is exposed to a peripheral edge of the piezoelectric sheet.
