摘要

纵扭型变换器采用扭转/纵向组合振动，大大简化了超声电机的结构，使小型化更加可行。这类电机的先前设计使用了多层压电驱动器。在本文中，我们报告了使用晶圆型作动器的电机的性能。这种电机设计需要减少压电材料的体积。

Novel ultrasonic motor using torsional/ longitudinal vibration

Longitudinal-torsional mode converters have greatly simplified the structure of ultrasonic motors using a combined torsional/ longitudinal vibration, making miniaturization more practical. A previous design of this type of motor used a multi-layer piezoelectric actuator. In this paper, we report on the performance of motors using wafer-type actuators. This motor design requires a reduced volume of piezoelectric material.
