圆环驻波型多自由度压电马达的研究

The Ring Type Multi-freedoms Piezoelectric Motor Using Standing Wave

首次提出一种新型的多自由度压电马达结构，分析了马达的工作原理。设计并研制了样机，进行了初步的实验，实验证明了理论分析的结果，为进一步的研究工作奠定了理论和实践基础。

For the first time, we bring forward a new kind of piezoelectric motor which can make the rotor running at multi-freedoms. We also described the drive-princple of this kind of motor, and make out the real device, at last, we proved our theory by experiment results. This kind of motor is only in its beginning phase, more advanced research should be made in the future.
