该系统的速度反馈元件采用测速发电机，角度测量元件采用光电编码器。

Measuring generator is used for velocity feedback in this system, and photoelectricity coding component is used for Angle measure.

本绕线式电动机转子电路脉冲调速系统模拟试验，省去了测速发电机，而利用转子电势组成速度负反馈系统。

The model test tried on this system did not use the tachometer generator but used rotor electromotive force instead to form the speed negative feed-back system.
