Piezoelectric Motor

Abstract

This report describes the technical aspects of a piezoelectric motor that was designed and successfully demonstrated at the Intelligent Servosystems Lab (ISL) of the University of Maryland at College Park. The motor was constructed with two piezoelectric benders and Lego blocks. It was driven by signals generated by the AC100 system and suitable voltage amplification. Using a similar procedure, one can make a smaller version that would be ideal for a small fan. Also described are the basic principles of the piezoelectric motor, an assessment of the motor, and ideas for improvement.
