摘　　要：介绍了一种基于尺蠖运动原理的大范围纳米级步距压电电动机。根据其运动原理和机械结构特点,设计完成了该压电电动机的控制系统,通过控制电压变化来控制压电晶体的伸缩,从而完成夹紧器的夹紧、放松与驱动器的微位移,巧妙的将压电陶瓷的形变通过机械装置输出,并对该控制系统进行了波形测试。实验表明,该控制系统产生的三角波、方波信号纹波电压小,信号稳定,满足电动机驱动要求。A kind of piezoelectric motor with Nano-step and long range, which is based on the principle of inchworm motion, is introduced in this paper. As to the characteristic of the mechanical structure of the motor, the driving and controlling system has been designed, which is used for controlling the clamper to clamp and relax. In this way the displacement of the piezoelectric ceramic is transferred to the motor. Then the waveform of the controlling system has been tested. The results show that both the triangle wave and the square wave are steady going and with little ripples. The system satisfies the requirements of the motor.
