JFEM电机引接线，旋转编码器的工作原理及作用
The working principle and function of rotary encoder
旋转编码器是用来测量转速的装置。它分为单路输出和双路输出两种。技术参数主要有每转脉冲数（几十个到几千个都有），和供电电压等。单路输出是指旋转编码器的输出是一组脉冲，而双路输出的旋转编码器输出两组相位差 90 度的脉冲，通过这两组脉冲不仅可以测量转速，还可以判断旋转的方向。
A rotary encoder is a device for measuring speed. It is divided into two kinds of one - way output and two - way output. The main technical parameters are the number of pulses per turn (dozens to thousands of), and the supply voltage. Single path output means that the output of the rotary encoder is a set of pulses, while the dual output rotary encoder outputs two sets of pulses with 90 degrees of phase difference. Through these two sets of pulses, the rotation speed can be measured and the direction of rotation can be judged.
增量型编码器与**型编码器的区分
The distinction between incremental encoders and absolute encoders
编码器如以信号原理来分，有增量型编码器,**型编码器。
If the encoder is based on ** principle, there are incremental encoders and absolute encoders.

Working principle:
由一个中心有轴的光电码盘，其上有环形通、暗的刻线，有光电发射和接收器件读取,获取四组正弦波信号组合成 A、B、C、D,每个正弦波相差 90 度相位差（相对于一个周波为360 度），将 C、D 信号反向，叠加在 A、B 两相上，可增强稳定信号；另每转输出一个 Z相脉冲以代表零位参考位。
A photoelectric encoder with a central axis, which has a circular and dark line, is read by photoelectric emission and receiving devices. Four sets of sine wave **s are combined into A, B, C, D, each sine wave is 90 degrees phase difference (relative to a circumferential wave of 360), and the C and D **s are reversed and superimposed on the A and B two phases. Strong stable **; output another Z phase pulse at each turn to represent zero reference bit.

由于 A、B 两相相差 90 度，可通过比较 A 相在前还是 B 相在前，以判别编码器的正转与反转，通过零位脉冲，可获得编码器的零位参考位。
Because the phase difference between A and B is 90 degrees, the coder's zero bit reference bit can be obtained by comparing the A phase before or before the B phase, to distinguish the forward and reverse of the encoder.
