DOME TYPE PIEZOELECTRIC MOTOR FOR OFFERING ENHANCED DISPLACEMENT

摘要

PURPOSE: A dome piezoelectric motor providing improved displacement is provided to improve the displacement by forming plural operating frequencies of a dome piezoelectric ceramic. CONSTITUTION: A dome piezoelectric ceramic(100) is composed to form different electrodes on both sides. The dome piezoelectric ceramic is composed to form a multiple relation for a first operating frequency. A vibration axis(110) is fixed to a side of the dome piezoelectric ceramic. A moving unit(200) is in contact with the vibration axis. The moving object is linearly operated by friction with the vibration axis.
