摘 要: 介绍了一种采用数控模拟开关和大功率运放的角度位置信号同步相敏解调电路。此电路应用于永磁低速同步电动机角度随动系统,相对于传统的角度随动和指示系统,可使整个系统结构简单,控制精度提高。试验结果证明该方案具有很好的工程适用性。 A novel phase synchronously demodulating circuit was introduced in this paper, in which digital controlled analog switch and high power amplifier were adopted. Low speed PM synchronous motor was used in this angular servo system,to make the whole system to get a more compact structure and higher precision. The experiments showed that the design was engineering practical.
