轉(zhuǎn)子用直流電進(jìn)行勵(lì)磁。它的轉(zhuǎn)子做成顯極式的，安裝在磁極鐵芯上面的磁場(chǎng)線圈是相互串聯(lián)的，接成具有交替相反的極性，并有兩根引線連接到裝在軸上的兩只滑環(huán)上面。磁場(chǎng)線圈是由一只小型直流發(fā)電機(jī)或蓄電池來(lái)激勵(lì)，在大多數(shù)同步電動(dòng)機(jī)中，直流發(fā)電機(jī)是裝在電動(dòng)機(jī)軸上的，用以供應(yīng)轉(zhuǎn)子磁極線圈的勵(lì)磁電流。

　　由于這種同步電動(dòng)機(jī)不能自動(dòng)啟動(dòng)，所以在轉(zhuǎn)子上還裝有鼠籠式繞組而作為電動(dòng)機(jī)啟動(dòng)之用。鼠籠繞組放在轉(zhuǎn)子的周圍，結(jié)構(gòu)與異步電動(dòng)機(jī)相似。

　　當(dāng)在定子繞組通上三相交流電源時(shí)，電動(dòng)機(jī)內(nèi)就產(chǎn)生了一個(gè)旋轉(zhuǎn)磁場(chǎng)，鼠籠繞組切割磁力線而產(chǎn)生感應(yīng)電流，從而使電動(dòng)機(jī)旋轉(zhuǎn)起來(lái)。電動(dòng)機(jī)旋轉(zhuǎn)之后，其速度慢慢增高到稍低于旋轉(zhuǎn)磁場(chǎng)的轉(zhuǎn)速，此時(shí)轉(zhuǎn)子磁場(chǎng)線圈經(jīng)由直流電來(lái)激勵(lì)，使轉(zhuǎn)子上面形成的磁極，這些磁極就企圖跟蹤定子上的旋轉(zhuǎn)磁極，這樣就增加電動(dòng)機(jī)轉(zhuǎn)子的速率直至與旋轉(zhuǎn)磁場(chǎng)同步旋轉(zhuǎn)為止。
