TACHOMETERgenerator, a small electric generator for supplying current at a frequency proportional to the speed of rotation.
测速发电机，提供频率与转速成比例的电流的小发电机。

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

An algorithm of unoscillation spot is given by example, and a practical method of tachometergenerator installation is presented as well.
