Linear piezoelectric motor with self locking means

摘要

A linear piezoelectric motor which includes a piezoelectric actuator; an actuator container which contains the piezoelectric actuator; an actuator slope which is supported by and slidably connected to an actuator slope support, the actuator slope is able to correspond with a surface portion of the actuator container; an output bar which shares a common axis with the actuator and the actuator container and comes in contact with at least one of the actuator and the actuator container on one end of the output bar and an axial load is applied on an opposite end of the output bar; and at least one output slope which is slidably connected to at least one output support.
