要改變輸入頻率、電機(jī)轉(zhuǎn)差率、電機(jī)磁極對(duì)數(shù)，任意一項(xiàng)即可以改變電動(dòng)機(jī)轉(zhuǎn)速，改變電機(jī)磁極對(duì)數(shù)調(diào)速是極的，即選用多極電動(dòng)機(jī)，但多極電動(dòng)機(jī)繞組比較復(fù)雜。
　　而改變電機(jī)轉(zhuǎn)差率調(diào)速又是不經(jīng)濟(jì)的，對(duì)鼠籠型異步電動(dòng)機(jī)只有改變其頻率，才是既經(jīng)濟(jì)又現(xiàn)實(shí)的調(diào)速方式，所以通過改變電動(dòng)機(jī)工作電源頻率達(dá)到改變電機(jī)轉(zhuǎn)速的目的，被稱為變頻調(diào)速，而變頻器就是主要依靠這個(gè)起作用的裝置。
