style="text-indent:25px">同步電機(jī)和感應(yīng)電機(jī)一樣是一種常用的交流電機(jī)。特點(diǎn)是穩(wěn)態(tài)運(yùn)行時(shí)，轉(zhuǎn)子的轉(zhuǎn)速和電網(wǎng)頻率之間有不變的關(guān)系n=ns=60f/p，ns成為同步轉(zhuǎn)速。若電網(wǎng)的頻率不變，則穩(wěn)態(tài)時(shí)同步電機(jī)的轉(zhuǎn)速恒為常數(shù)而與負(fù)載的大小無關(guān)。同步電機(jī)分為同步發(fā)電機(jī)和同步電動(dòng)機(jī)?，F(xiàn)代發(fā)電廠中的交流機(jī)以同步電機(jī)為主。主磁場的建立勵(lì)磁繞組通以直流勵(lì)磁電流，建立極性相間的勵(lì)磁磁場，即建立起主磁場。載流導(dǎo)體：三相對稱的電樞繞組充當(dāng)功率繞組，成為感應(yīng)電勢或者感應(yīng)電流的載體。切割運(yùn)動(dòng)：原動(dòng)機(jī)拖動(dòng)轉(zhuǎn)子旋轉(zhuǎn)（給電機(jī)輸入機(jī)械能），極性相間的勵(lì)磁磁場隨軸一起旋轉(zhuǎn)并順次切割定子各相繞組（相當(dāng)于繞組的導(dǎo)體反向切割勵(lì)磁磁場）。 </p><p style="text-indent:25px">單相交流電動(dòng)機(jī)只有一個(gè)繞組，轉(zhuǎn)子是鼠籠式的。當(dāng)單相正弦電流通過定子繞組時(shí)，電動(dòng)機(jī)就會(huì)產(chǎn)生一個(gè)交變磁場，這個(gè)磁場的強(qiáng)弱和方向隨時(shí)間作正弦規(guī)律改變，但在空間方位上是固定的，所以又稱這個(gè)磁場是交變脈動(dòng)磁場。這個(gè)交變脈動(dòng)磁場可分解為兩個(gè)以相同轉(zhuǎn)速、旋轉(zhuǎn)方向互為相反的旋轉(zhuǎn)磁場，當(dāng)轉(zhuǎn)子靜止時(shí)，這兩個(gè)旋轉(zhuǎn)磁場在轉(zhuǎn)子中產(chǎn)生兩個(gè)大小持平、方向相反的轉(zhuǎn)矩，使得組成轉(zhuǎn)矩為零，所以電動(dòng)機(jī)無法旋轉(zhuǎn)。當(dāng)咱們用外力使電動(dòng)機(jī)向某一方向旋轉(zhuǎn)時(shí)（如順時(shí)針方向旋轉(zhuǎn)），這時(shí)轉(zhuǎn)子與順時(shí)針旋轉(zhuǎn)方向的旋轉(zhuǎn)磁場間的切開磁力線運(yùn)動(dòng)變?。晦D(zhuǎn)子與逆時(shí)針旋轉(zhuǎn)方向的旋轉(zhuǎn)磁場間的切開磁力線運(yùn)動(dòng)變大。這樣平衡就打破了，轉(zhuǎn)子所產(chǎn)生的總的電磁轉(zhuǎn)矩將不再是零，轉(zhuǎn)子將順著推動(dòng)方向旋轉(zhuǎn)起來。減速電機(jī)是指減速機(jī)和電機(jī)（馬達(dá)）的集成體。</p><div
