variable voltage speed control

基本解释

Variable voltage and variable frequency system based on vector control is applied widely in high speed train.
基于矢量控制的变压变频调速在高速列车中得到广泛应用。
The machine uses a direct far-infrared radiation heating, electronic variable speed, solid state voltage regulator temperature control, stable and reliable;
该机采用远红外线辐射直接加热，电子无级变速，固态调压器控温，稳定可靠；
Being a simple and reliable speed control system for AC inductive motors, the device features better performance than AC variable voltage speed control system does.
本装置的性能优于交流调压调速系统，是一种简单而可靠的交流绕线式电动机转速控制系统。
