變頻調(diào)可平滑調(diào)速，調(diào)速范圍寬和節(jié)能等優(yōu)點在提升機上得到了廣泛的應(yīng)用，礦井提升機一般對變頻器有以下要求：

1．礦用電網(wǎng)波動較大，變頻器在380V±20%能正常工作。

2．運行平穩(wěn)，加減速平滑，S型曲線加速段，在加減速過程中可做到加速度連續(xù)，無撞擊感。

3．對回饋能量的處理方法：回饋制動或能耗制動。

4．變頻器在整個工作過程中提供所需要的力矩特性：

啟動力矩大于2倍額定轉(zhuǎn)矩，尤其是當(dāng)?shù)V車停在井筒中間時，啟動轉(zhuǎn)矩比額定轉(zhuǎn)矩大得多。低頻轉(zhuǎn)矩在3Hz時大于1.6倍額定轉(zhuǎn)矩。
