Working Principle and Design of a Cylindrical Standing Wave Ultrasonic Motor Using Cantilever Type Bending Transducer

Abstract:

A cylindrical standing wave ultrasonic motor using cantilever type bending transducer is proposed in this paper. There are four cantilevers outside the cylinder, and four PZT ceramics are set on each end surface of cantilevers. The bending mode of cylinder is excited by the bending vibration of transducers. Thus, a linear simple harmonic motion is achieved at the particle on the tooth. The working principle of proposed motor is analyzed. The cylinder and transducer are designed with FEM. The bending vibration modals of transducer and cylinder are degenerated. The transient analysis is developed to gain the vibration characteristics of stator, and the results indicate 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 motor.
