style="text-indent:25px">單相交流電動機(jī)只有一個繞組，轉(zhuǎn)子是鼠籠式的。當(dāng)單相正弦電流通過定子繞組時，電動機(jī)就會產(chǎn)生一個交變磁場，這個磁場的強(qiáng)弱和方向隨時間作正弦規(guī)律改變，但在空間方位上是固定的，所以又稱這個磁場是交變脈動磁場。這個交變脈動磁場可分解為兩個以相同轉(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，這兩個旋轉(zhuǎn)磁場在轉(zhuǎn)子中產(chǎn)生兩個大小持平、方向相反的轉(zhuǎn)矩，使得組成轉(zhuǎn)矩為零，所以電動機(jī)無法旋轉(zhuǎn)。當(dāng)咱們用外力使電動機(jī)向某一方向旋轉(zhuǎn)時（如順時針方向旋轉(zhuǎn)），這時轉(zhuǎn)子與順時針旋轉(zhuǎn)方向的旋轉(zhuǎn)磁場間的切開磁力線運動變??；轉(zhuǎn)子與逆時針旋轉(zhuǎn)方向的旋轉(zhuǎn)磁場間的切開磁力線運動變大。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)子將順著推動方向旋轉(zhuǎn)起來。交流同步電動機(jī)是一種恒速驅(qū)動電動機(jī)。上海直驅(qū)電機(jī)價錢</p><p
