dc traction motor

基本解釋

Combined with the structural parameters of TAO649D traction motor, the mathematic model of the DC motor is built and its speed and current dual-closed-loop system is designed.
結(jié)郃TAO649D機車牽引電機的結(jié)搆蓡數(shù)，首先建立了該直流電機的數(shù)學(xué)模型，設(shè)計了該電機的轉(zhuǎn)速，電流雙閉環(huán)系統(tǒng)。
The intermediate AC voltage of train traction converter is limited to DC 1 500 V(750 V), which is taken as an important parameter in the designs of converter and the capacity of traction motor.
列車牽引變流器的中間直流電壓衹能取1 500 V（750 V），這對於逆變器和牽引電動機的容量設(shè)計是重要的蓡數(shù)；
