本电路给出对一分相器(机电轴位置传感器)提供激励和用16位分辨力数字化所得到的转子信号的奇妙方法。电路用正弦和余弦波形驱动分相器的两组定子绕组,然后用PLL(IC_4)和16位分频器(级联的计数器IC_5和IC_6)转换转子输出。此转换率为60采样/秒。因为分相器定子信号是正交的,它们在分 This circuit gives a fantastic way to provide excitation of a phase splitter (electromechanical shaft position sensor) and digitizing the resulting rotor signal with 16-bit resolution. The circuit drives both sets of stator windings of the phase splitter with sine and cosine waveforms and then converts the rotor output with a PLL (IC_4) and a 16-bit divider (cascaded counters IC_5 and IC_6). This conversion rate is 60 samples / second. Because the phase splitter stator signals are orthogonal, they are in the minute
