Abstract

A kind of ultrasonic motor, in which a rotation shaft is used to pass through the axial hole of the piezoelectric device. Additionally, the rotor or the contact portion of the rotating shaft is used to slide and contact both ends of the axial hole. Therefore, it is capable of controlling the relative position for combining the rotor or the contact portion on the rotating shaft to easily control the contact pre-stressing force and provide the effect of adjusting the contact pre-stressing force.
