矿井提升机的电力拖动

Electric drive of mine hoist

根据矿井提升机电力拖动技术发展的三个阶段，介绍和分析了绕线型异步电动机交流拖动、发电机－电动机直流拖动、晶闸管整流装置供电的直流拖动和交－交变频器供电的交流拖动等四种拖动方式。

According to three developing stage of mine hoist electric drive,this paper introduces and analysises the AC drive of wound rotor induction,DC drive of generator motor ,DC drive of thyristor power rectifier and AC drive of AC AC varying frequency.
