Stator and ceramic tube type ultrasonic motor using the same |
摘要 |
The present invention relates to a ceramic tube type ultrasonic motor having a stator including a tube-type elastic body that is formed of a ceramic material; and a plurality of piezoelectric diaphragms that are attached on the outer peripheral surface of the elastic body in a longitudinal direction thereof and to which voltages having a phase difference are respectively applied and a rotor that is rotated by the friction with the elastic body flexurally vibrating due to the voltages applied to the plurality of piezoelectric diaphragms.
