Abstract
The present invention relates to a piezoelectric motor. The piezoelectric motor of the invention comprises a piezoelectric stator, a shaft, a rotator, an elastic component, and a fixing component. The piezoelectric stator at least has a plurality of piezoelectric ceramic piece for supporting surface standing wave. The shaft passes through the piezoelectric stator to couple to the rotator, the elastic component, and the fixing component for applying a driving voltage and mode-resonant frequency to complete rotation movement to solve known defects of prior art.
