Abstract

Abstract This work presents an ingenious mechanism using dual frictional-drive (DFD) for surface acoustic wave (SAW) linear motor resulting in significantly compact and lightweight design. The device uses two synchronous Rayleigh waves propagating on two 128° rotated y-cut x-propagated lithium niobate (LiNbO3) piezoelectric stators facing each other and driving a cylindrical slider held tightly between the stators in translational motion. By reversing the direction of propagation of both the SAWs, the direction of motion of the slider can be reversed. The experimental results of the proposed SAW motor demonstrate the novel mechanism to form the device where the slider is attaining a steady state velocity of 1.28 m/s for a continuous wave excitation of frequency 13.5 MHz.

采用圆柱轴作为外部负载驱动器的双摩擦驱动SAW电机

摘要:本研究提出了一种巧妙的双摩擦驱动(DFD)表面声波(SAW)直线电机的机制，从而实现了显著的紧凑和轻量化设计。该装置使用两个同步瑞利波在两个128°旋转的y切x传播铌酸锂(LiNbO3)压电定子上传播，并驱动一个圆柱形滑块，该滑块紧靠在定子之间进行平移运动。通过反转两个saw的传播方向，滑块的运动方向可以反转。实验结果表明，在频率为13.5 MHz的连续波激励下，该滑块达到1.28 m/s的稳态速度。
