摘要:
A piezoelectric motor for generating an elliptic motion by adding a longitudinal vibration to a bending-direction vibration is provided. The piezoelectric motor includes a piezoelectric member which generates a first vibration mode and a second vibration mode simultaneously by an applied power and a frictional member of which a portion is insertedly attached into a concave portion indentedly formed on one side of the piezoelectric member, wherein the frictional member is in an elliptic motion by the vibration generated by the piezoelectric member, so that an influence of the attachment of the frictional member to a resonance frequency can be minimized. Accordingly, a driving efficiency of the piezoelectric motor can be improved. In addition, attachment strength of the frictional member can be improved.
