style="text-indent:25px">當三相異步電機接入三相交流電源時，三相定子繞組流過三相對稱電流產(chǎn)生的三相磁動勢（定子旋轉(zhuǎn)磁動勢）并產(chǎn)生旋轉(zhuǎn)磁場。該旋轉(zhuǎn)磁場與轉(zhuǎn)子導(dǎo)體有相對切割運動，根據(jù)電磁感應(yīng)原理，轉(zhuǎn)子導(dǎo)體產(chǎn)生感應(yīng)電動勢并產(chǎn)生感應(yīng)電流。根據(jù)電磁力定律，載流的轉(zhuǎn)子導(dǎo)體在磁場中受到電磁力作用，形成電磁轉(zhuǎn)矩，驅(qū)動轉(zhuǎn)子旋轉(zhuǎn)，當電動機軸上帶機械負載時，便向外輸出機械能。異步電機是一種交流電機，其負載時的轉(zhuǎn)速與所接電網(wǎng)的頻率之比不是恒定關(guān)系。還隨著負載的大小發(fā)生變化。負載轉(zhuǎn)矩越大，轉(zhuǎn)子的轉(zhuǎn)速越低。異步電機包括感應(yīng)電機、雙饋異步電機和交流換向器電機。感應(yīng)電機應(yīng)用較廣，在不致引起誤解或混淆的情況下，一般可稱感應(yīng)電機為異步電機。無刷直流電動機是采用半導(dǎo)體開關(guān)器件來實現(xiàn)電子換向的。上海科爾摩根防水伺服電機費用</p><p

style="text-indent:25px">減速電機分類為大功率齒輪減速電機、同軸式斜齒輪減速電機、平行軸斜齒輪減速電機、螺旋錐齒輪減速電機、YCJ系列齒輪減速電機，減速電機普遍應(yīng)用于冶金、礦山、起重、運輸、水泥、建筑、化工、紡織、印染、制藥等各種通用機械設(shè)備的減速傳動機構(gòu)。變頻技術(shù)實際是利用電機控制學(xué)原理，通過所謂的變頻器，對電機進行控制。用于此類控制的電機叫做變頻電機。常見的變頻電機包括：三相異步電機、直流無刷電機、交流無刷電機及開關(guān)磁阻電機等。通常變頻電機的控制策略為：基速下恒轉(zhuǎn)矩控制、基速以上恒功率控制、超高速范圍弱磁控制。福建科爾摩根防水伺服電機</p><p
