Thread drive polyhedral ultrasonic motor

摘要

This invention belongs to the field of ultrasonic application in regard to the ultrasonic motor drive of the thread attachment. The mechanism consists of with the stator and the rotor of the thread attachment, that stator is formed, from the piezoelectric ceramic seat which glues in the metal polyhedron and that polyhedron of air. The stator as the rotor in order to turn, is driven with the thread, converts rotation of the rotor to linear motion with the thread. As for this invention, constitution being simple, it can lose other transmission mechanism, being suited well by minute type conversion, in field such as minute type machine and optical focusing the application possibility there is.
