ABSTRACT:
A vibratory-wave motor which forms a progressive vibratory wave with a frequency signal applied to a piezoelectric body is arranged to permit adjustment of a torque of contact with its rotor by adjusting as desired the driving frequency of the signal particularly when the motor is operated in a mode in which a stationary wave is formed instead of the progressive vibratory wave.
