摘　　要：为了满足当前精密仪器对压电马达小尺寸,大扭矩的要求,设计了一种倾斜式压电低频马达,这种马达不仅节约成本,且能由低频电源驱动,使用范围比高频压电马达广泛。该文研究了这种马达驱动能力形成的机理,建立了驱动结构的动力学模型,根据试验研究的需要制作了样机,并对样机进行了实验测试,完成了输入频率对输出转速和输出扭矩影响的实验研究。结果表明,新型低频压电马达在输入频率为290Hz时性能最优。In order to meet the requirements of small size and high torque piezoelectric motor for precision in- struments applications, a new type of low frequency piezoelectric-motor is designed in this paper. The proposed pie- zoelectric motor has the features of cost-effectiveness, low frequency power drive and wider application over high frequency piezoelectric-motor. The driven mechanism of the motor was studied and the dynamic model of the driving structure was established. A prototype was fabricated and tested. The effect of input frequency on output torque and speed were carried out. The tests showed that tile new type of low frequency piezoelectric-motor has best operating performance at 290 Hz.
