交流電機(jī)雖然結(jié)構(gòu)簡單,但是工作原理其實(shí)比直流電機(jī)要復(fù)雜一點(diǎn),如果要理解清楚也更加費(fèi)勁。在交流電機(jī)的定子上通上三相對稱交流電,如上圖所示,定子不動(dòng),僅僅通過電流的變化就能產(chǎn)生旋轉(zhuǎn)的合成磁場,這個(gè)磁場像一個(gè)繞著定子旋轉(zhuǎn)的磁鐵。有了這個(gè)旋轉(zhuǎn)的磁鐵,一切就都好辦了,在定子內(nèi)部隨便放一個(gè)閉合的線圈,在這個(gè)閉合線圈里就會(huì)感應(yīng)出電動(dòng)勢和電流,就會(huì)產(chǎn)生電磁力,閉合線圈就會(huì)轉(zhuǎn)動(dòng)起來。也可以這么理解,定子上有一個(gè)旋轉(zhuǎn)的磁鐵,轉(zhuǎn)子閉合線圈由于感應(yīng)帶電,其實(shí)也變成了一個(gè)電磁鐵,外面的電磁鐵在轉(zhuǎn),就會(huì)帶著里面的電磁鐵轉(zhuǎn),于是交流電機(jī)的轉(zhuǎn)子就轉(zhuǎn)起來了。
