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.
基於矢量控制的變壓變頻調速在高速列車中得到廣泛應用。
The machine uses a direct far-infrared radiation heating, electronic variable speed, solid state voltage regulator temperature control, stable and reliable;
該機採用遠紅外線輻射直接加熱，電子無級變速，固態調壓器控溫，穩定可靠；
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.
本裝置的性能優於交流調壓調速系統，是一種簡單而可靠的交流繞線式電動機轉速控制系統。
