三相異步電動(dòng)機(jī)的調(diào)速方法三相異步電動(dòng)機(jī)的調(diào)速方法包括：變極對(duì)數(shù)、定子調(diào)壓、定子變頻、串級(jí)調(diào)速、雙饋調(diào)速、液力耦合、電磁轉(zhuǎn)差離合器等，從調(diào)速時(shí)的能耗觀點(diǎn)來(lái)看，有高效調(diào)速方法與低效調(diào)速方法兩種：高效調(diào)速指時(shí)轉(zhuǎn)差率不變，因此無(wú)轉(zhuǎn)差損耗，如多速電動(dòng)機(jī)、變頻調(diào)速以及能將轉(zhuǎn)差損耗回收的調(diào)速方法(如串級(jí)調(diào)速等)。有轉(zhuǎn)差損耗的調(diào)速方法屬低效調(diào)速，如轉(zhuǎn)子串電阻調(diào)速方法，能量就損耗在轉(zhuǎn)子回路中；電磁離合器的調(diào)速方法，能量損耗在離合器線(xiàn)圈中；液力耦合器調(diào)速，能量損耗在液力耦合器的油中。一般來(lái)說(shuō)轉(zhuǎn)差損耗隨調(diào)速范圍擴(kuò)大而增加，如果調(diào)速范圍不大，能量損耗是很小的。從異步電動(dòng)機(jī)的轉(zhuǎn)速公式可知，異步電動(dòng)機(jī)要想改變轉(zhuǎn)速，必須從以下三個(gè)方面考慮：改變電動(dòng)機(jī)定子繞組的磁極對(duì)數(shù)P，改變電動(dòng)機(jī)的轉(zhuǎn)差率S，改變電動(dòng)機(jī)供電源的頻率f，對(duì)應(yīng)于上述三個(gè)途徑的調(diào)速方法分別簡(jiǎn)稱(chēng)為：變極調(diào)速，變轉(zhuǎn)差率調(diào)速，變頻調(diào)速。1．變極調(diào)速（有級(jí)調(diào)速）由轉(zhuǎn)速公式可知，改變電動(dòng)機(jī)定子繞組的磁極對(duì)數(shù)P，就可以改變其同步轉(zhuǎn)速，從而使運(yùn)行速度發(fā)生變化。達(dá)到調(diào)速的目的，但是異步電動(dòng)機(jī)只有定子、轉(zhuǎn)子磁極對(duì)數(shù)相同時(shí)，定子、轉(zhuǎn)子磁勢(shì)才能相互作用產(chǎn)生磁轉(zhuǎn)矩。
