TURNING PIEZOELECTRIC MOTOR USING A CAM

摘要

A turning piezoelectric motor using a cam is provided to allow reciprocation motion partly without the structural change of the piezoelectricity linear motor. A rotation piezoelectric motor comprises a piezoelectric drive(100), a cam, and a rotator(300). A piezoelectric driving unit comprises a driving shaft(130), and a driving shaft performs liner movement according to the physical displacement generated by the driving shaft. The cam and the driving shaft are assembled, and it linearly moves according to the liner movement of the driving shaft. A guide groove(310) is formed on the outer circumference of the rotator, and a part of the cam is inserted into it. The rotator rotates according to the linear motion of the cam including a moving body(210) and a cam projection(220). The moving body is assembled with the driving shaft, and linearly moves.
