超声电机性能的实验测试研究

Experimental testing and research of the ultrasonic motor performance

超声电机是一种全新概念的新型电机,它利用压电材料的逆压电效应,使定子表面产生一定轨迹的微米量级的振动,进而通过摩擦耦合将振动动能转换成转子或滑块的宏观运动(转动或平动)动能,文章探究了在不同予应力的作用下电机的频率、相位对转速的影响。该研究为超声电机转速的控制提供了理论依据。

The ultrasonic motor is a new concept, new motor using piezoelectric materials converse piezoelectric effect, make the stator surface of certain track, then the sub-micrometer range by friction coupling vibration of rotor vibration energy will be converted or slide block or translational motion （macro）, this paper explores the energy to stress at different under the action of the frequency, phase of motor speed. The study of ultrasonic motor speed control provides theory basis.
