<p>A piezoelectric motor (10) comprising a stator (12); a rotor (14) having a rotor inner circumferential surface; a piezoelectric element (16) retained on the stator; power supply means in communication with said piezoelectric element to operably effect longitudinal resilient mechanical oscillations in the element; a plurality of pusher members (18) each having (a) at least one first portion (38, 39) defining a pusher abutting surface abutting the rotor inner surface, (b) at least one second portion (42, 44) defining a piezoelectric element engaging surface distal of the pusher abutting surface, and (c) a third portion (34) defining a retained surface; retainer means (20) in abutment with the pusher member retained surface to releasably retain the pusher member in abutment with the piezoelectric element engaging surface and the rotor inner surface and wherein the longitudinal resilient mechanical oscillations effect coplanar movement of the pusher member; and the first portion is so shaped and inclined as to operably effect circumferential movement of the circumferential surface when the pusher member conducts longitudinal resilient mechanical movements induced by the piezoelectric effect element to effect rotary movement of the rotor inner circumferential surface relative to the piezoelectric element. The motor can be readily disasssembled and repaired.</p> |
