中文摘要:
      超声电机驱动电源一般是通过调占空比实现超声电机的控制。文中介绍一种由单片机控制可以同时实现调频、调占空比和调相位差的驱动与控制线路。实验结果表明:该驱动源频率变化范围达20kHz~100kHz;相位差0°~90°可调;占空比0.1~0.5可调。
英文摘要:
      Usually pulse width modulation is used to control ultrasonic motor. In this paper, a new driving circuit is presented, in which pulse width modulation and frequency modulation and phase modulation can be realized. Experiment results show that frequency can be adjusted from 20kHz to 100kHz, pulse width modulation is 0.1 to 0.5, and phase shift is 0 to π/2.
