| Abstract: | A new kind of piezoelectric micromotor was shown. This kind of micro piezoelectric motor has a simple structure and is easy to be miniaturized. Based on the piezoelectric theory, mechanical vibration and elasticity mechanics, this paper analysed this piezoelectric micromotor vibrators and investigated its work principle. A mathematical model of piezoelectric micromotor in kinematics and dynamics was established, which set up the theory foundation for the piezoelectric micromotor's structure optimization. |
