摘要:
为了实现双柔铰导向式双足压电直线电机连续和步进2种作动模式,电机的驱动电源需要产生不同类型的驱动信号,并且通过改变驱动信号的幅值或频率可以改变电机的运行速度。根据该驱动要求采用嵌入式微处理器PSoC作为信号发生单元,应用直接数字式合成器技术产生3种模式的4路驱动信号,利用LM358构成的两级电压放大电路,再通过IRF630构成的功率放大电路对信号进行电压与功率放大。实验表明,该驱动电源能够输出不同模式的信号,输出电压幅值调节范围为0～120 V,频率调节范围为0～2 kHz,能够实现电机的工作模式、运行速度与运行方向的调节。
Abstract:
In order to realize the continuous and step-by-step actuation modes of double-foot piezoelectric linear motor with double flexible hinges, it is necessary for the driving power of the motor to produce different driving signals. In addition, the running speed of the motor can be changed by adjusting the amplitude or frequency of the driving signals. According to the requirement of this driving motor, PSoC, the embedded micro-processor, was firstly taken as the main unit to generate signals. Then, 4 driving signals in 3 modes were produced by using the direct digital synthesizer. Finally, the voltage and power of the signal was amplified by the LM358 two-stage voltage amplifier circuit and the IRF630 power amplifier circuit. The experimental results show that the proposed driving power can generate driving signals in different modes with the output voltage amplitude ranging 0～120 V and frequency ranging 0～2 kHz, and can adjust the working mode of the motor and the operating speed and direction.
