PIEZO ELECTRIC MOTOR

摘要

A piezoelectric motor is provided to improve performance of the motor by providing the large friction with a simple configuration. A piezoelectric motor(100) includes a piezoelectric body(110) and a pair of driving members(121,122). A piezoelectric body includes a piezoelectric element inducing the mechanical vibration by the voltage applied from the outside. The penetration hole receiving at least part of a driving object is formed in the piezoelectric body. A pair of driving members are arranged to face each other while interposing the penetration hole at an outer side of the piezoelectric body. The pair of driving members drive the driving members by providing the friction driving force to both sides of the driving object through the vibration of the piezoelectric body.
