摘要
设计了一种压电驱动低频旋转驱动器,这种旋转驱动器是采用晶片型压电振子进行驱动,驱动器驱动频率低,输出功率大。首先对旋转驱动器的结构进行了结构设计与工作原理分析,然后建立旋转驱动器系统的动力学模型,对转子进行了受力分析,得出系统输出位移和固有频率表达式以及转子旋转需要的条件。根据理论分析制作了旋转驱动器样机,并对系统进行了测试,实验结果表明,该旋转驱动器的最佳工作频率为264 Hz,当驱动电压为200 V时,最大转速为17.8 r/min,输出扭矩最大为0.025 N·m。
In this paper,a low frequency piezoelectric rotating actuator is designed. The piezoelectric rotation actuator is driven by a wafer-type piezoelectric vibrator with low drive frequency and high efficiency output. Firstly,the structure design and mechanism analysis of the low frequency rotating actuator are carried out. Then,the dynamic model of the rotating system is established. Through force analysis of the actuator rotor,the natural frequency expression of the system and the conditions required for rotor rotation are obtained. According to the theoretical analysis,an experimental prototype is fabricated and tested. The results show that when the frequency is 264 Hz the piezoelectric actuator has the best performance. The maximum speed is 17.8 r/min,and the maximum output torque is 0.025 N·m at a driving voltage of 200 V.
