Research of a Ring-Type Linear Ultrasonic Motor

Abstract:

A new ring-type linear ultrasonic motor is proposed in this study. In this new design, bending vibration traveling wave is generated in a long ring by two groups of PZT ceramics bonded on the inner sides of the linear beams. Elliptical trajectory motions can be formed at particles on the teeth, which can realize the linear driving by frictional force. The working principle of the proposed design is introduced. Two bending vibration modes that have a phase difference of 90deg on space are analyzed. The elliptical motion trajectory of node on the tooth gained by the transient analysis verifies the excitation of bending traveling wave. A prototype motor is fabricated and measured, and a maximum speed of 15mm/s is reached.
