摘要：
Ultrasonic motors adopting longitudinal vibration of bar were widely studied for their considerable thrust, high efficiency and reliability. A novel ultrasonic motor using longitudinal vibration of bar with varying section was proposed in this paper. This ultrasonic motor features with two varying section bars connected by semi-circumferential structure. Elliptical trajectories of particles are formed on top of the semi-circumferential structure outer surface where driving foot located and a mover is pushed to move when the driving foot is pressed onto it. FE model of its stator was built and results of harmonic analysis verified its principle. Testing of prototype shows that this motor was capable of a 10N load with speed 100mm/s.
