Abstract
A piezoelectric motor comprising: a piezoelectric vibrator having an axis of symmetry and a first vibration mode, which when excited generates oscillatory motion of mass points in the vibrator parallel to the axis of symmetry; and at least one friction nub having a center of mass displaced from the axis of symmetry, as a result of which displacement, when the vibration mode is excited, torque is generated on the vibrator that excites a second vibration mode of the vibrator.
