Design and Analysis of a Cylindrical Traveling Wave Ultrasonic Motor Using Composite Transducer

Abstract:

A cylindrical type traveling wave ultrasonic motor using composite transducer is proposed in this paper. A composite transducer is attached to the cylinder on its outer surface to excite two degenerate flexural vibration modes spatially and temporally orthogonal to each other in the cylinder. In this new design, a single transducer can excite the flexural traveling wave in the cylinder. Thus, an elliptical motion is achieved at the particle on the tooth. And the driving force is the frictional force between rotor and teeth. The working principle of proposed motor is analyzed. The cylinder and transducer are designed with FEM. The sensitive parameters of resonance frequencies of transducer and cylinder are gained with modal analysis. The resonance frequencies of two vibration modals of stator are degenerated, and the motion trajectories of nodes on the teeth are analyzed. The result of transient analysis shows that the trajectory of node on the tooth is nearly an ellipse. The results of this paper could guide the development of this new type of motor.
