ABSTRACT:
A piezoelectric motor constructed so as to convert deformation movements of a plurality of electrostrictive elements to a rotatory movement and then to output it through an output shaft as rotary power at a low speed. The piezoelectric motor includes a plurality of electrostrictive elements, a disk-shaped precessional movement plate supported to be driven by the deformations of these electrostrictive elements and to perform a precessional movement without rotation on its axis, a rotary plate arranged to be driven at a reduced speed by a circumferential difference between circular paths described by contact under pressure, at a precessional angle .theta. with a peripheral portion of the precessional movement plate. An output shaft is operatively connected to the rotary plate to deliver output power.
