A Phase Synchronously Demodulating Circuit Used in an Angular Servo System
LU Yong-ping · Small & Special Electrical Machines · 2007
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.
