51309276-150變頻調(diào)速
從式(1—1)中可以看出,當(dāng)異步電動機(jī)的磁對數(shù)Pn定,轉(zhuǎn)差率s—定時,改變定子繞組的供電頻率f1可以達(dá)到調(diào)速目的,電動機(jī)轉(zhuǎn)速n基本上與電源的頻率f1成正比,因此,平滑地調(diào)節(jié)供電電源的頻率,就能平滑,無級地調(diào)節(jié)異步電動機(jī)的轉(zhuǎn)速。變頻調(diào)速調(diào)速范圍大,低速特性較硬,基頻f=50Hz以下,屬于恒轉(zhuǎn)矩調(diào)速方式,在基頻以上,屬于恒功率調(diào)速方式,與直流電動機(jī)的降壓和弱磁調(diào)速十分相似。且采用變頻起動更能顯著改善交流電動機(jī)的起動性能,大幅度降低電機(jī)的起動電流,增加起動轉(zhuǎn)矩。所以變頻調(diào)速是交流電動機(jī)的理想調(diào)速方案。
