Article Preview

A square-type rotary ultrasonic stator using longitudinal vibration transducers is proposed. The proposed stator contains four longitudinal vibration transducers, which are located in square-type. Every longitudinal transducer includes two exponential shape horns located on each end. And the horns of adjacent transducers intersected at tip ends where located the driving feet. The longitudinal vibrations of transducers are excited by the longitudinal vibrations of PZT ceramics. Longitudinal vibrations of adjacent transducers are superimposed in the driving foot and generated elliptical trajectory. The actuating mechanism is analyzed, and the motion trajectories of driving feet are deduced. The stator is designed and analyzed by using FEM method. The vibration characteristic of stator is gained by transient analysis. Results indicate that the motion trajectories of the four driving feet have good consistency, and the proposed motor has potential good output characteristics. The results of this paper verify the theoretical feasibility and provide instructions for the development of proposed stator.
