<p>The invention relates to a stand for the study of the operation of rotary piezoelectric motors with vibrating disc, in submerged environment. According to the invention, the stand consists of a transparent vessel () wherein a liquid medium () is placed, at its base there being a rotary piezoelectric motor with vibrating disc having a rotor () fixed, by means of a bearing shaft, onto a support () and brought into contact with a stator made of a vibrating disc (), on which a piezoelectric plate () is placed, insulated with a bitumen coat and fixed, by means of some vibration dampers, on a supporting arm () fixed, in its turn, by means of a flexible arm (), on a support (), the inclination of the plane of the vibrating disc () being adjustable by some screws (), while the pretensioning force is adjustable by a spring (), the piezoelectric element being supplied using a pulse generator.</p> |
