 矿井提升机是煤矿，有色金属矿生产过程中的重要设备。提升机的安全、可靠运行，直接关系到企业的生产状况和经济效益。某煤矿井下采煤，采好的煤通过斜井用提升机将煤车拖到地面上来。煤车厢与火车的运货车厢类似，只不过高度和体积小一些。在井口有一绞车提升机，由电机经减速器带动卷筒旋转，钢丝绳在卷筒上缠绕数周，其两端分别挂上一列煤车车厢，在电机的驱动下将装满煤的一列车从斜井拖上来，同时把一列空车从斜井放下去，空车起着平衡负载的作用，任何时候总有一列重车上行，不会出现空行程，电机总是处于电动状态。这种拖动系统要求电机频繁的正、反转起动，减速制动，而且电机的转速一定规律变化。斜井提升机的机械结构示意如图1所示。斜井提升机的动力由绕线式电机提供，采用转子串电阻调速。提升机的基本参数是：电机功率55kW，卷筒直径1200mm，减速器减速比24︰1， 运行速度2.5m/s，钢丝绳长度为120m。

   目前，大多数中、小型矿井采用斜井绞车提升，传统斜井提升机普遍采用交流绕线式电机串电阻调速系统，电阻的投切用继电器—交流接触器控制。这种控制系统由于调速过程中交流接触器动作频繁，设备运行的时间较长，交流接触器主触头易氧化，引发设备故障。另外，提升机在减速和爬行阶段的速度控制性能较差，经常会造成停车位置不准确。提升机频繁的起动﹑调速和制动，在转子外电路所串电阻的上产生相当大的功耗。这种交流绕线式电机串电阻调速系统属于有级调速，调速的平滑性差；低速时机械特性较软，静差率较大；电阻上消耗的转差功率大，节能较差；起动过程和调速换挡过程中电流冲击大；中高速运行震动大，安全性较差。
