style="text-indent:25px">所謂三相異步電動機的啟動是指電動機從接入電源開始轉(zhuǎn)動起，到達到額定轉(zhuǎn)速為止的這一過程。根據(jù)理論分析和實際測定，三相異步電動機啟動瞬間；定子繞組啟動電流很大，可達額定值的4~7倍。三相異步電動機為什么會有這么大的啟動電流呢？因為異步電動機在啟動瞬間轉(zhuǎn)子并不能立馬就轉(zhuǎn)動起來，此時轉(zhuǎn)子電磁感應(yīng)的反電勢尚未建立起來，所以外電壓全部加在沒有反電勢的定子繞組上，其電路電流就是外電壓除以繞組的阻抗（用符號Z表示，是一種對電流其阻礙作用的能力，單位為歐姆公式Z=V/I表示），所以定子繞組電流很大。這么大的啟動電流將帶來以下不良后果：使電網(wǎng)電壓產(chǎn)生波動（特別是容量較大的電動機啟動時），從而影響到接在電網(wǎng)上的其它設(shè)備的正常運行。使電動機繞組發(fā)熱，絕緣老化，從而縮短了電動機的使用壽命。特別是對經(jīng)常需要啟動的電動機影響較大。啟動瞬間，由于三相異步電動機轉(zhuǎn)子電路功率因素較低，啟動轉(zhuǎn)矩并不很大。如果啟動轉(zhuǎn)矩小于負載轉(zhuǎn)矩則電動機將無法啟動。綜上所述，三相異步電動機啟動時的主要缺點是啟動電流較大。為了減小啟動電流，必須采用適當(dāng)?shù)膯臃椒?。?lián)創(chuàng)電機重信譽、守合同，嚴(yán)把產(chǎn)品質(zhì)量關(guān)，熱誠歡迎廣大用戶前來咨詢考察，洽談業(yè)務(wù)！</p><div

同步電機，和感應(yīng)電機（即異步電機）一樣是一種常用的交流電機。同步電機是電力系統(tǒng)的心臟，它是一種集旋轉(zhuǎn)與靜止、電磁變化與機械運動于一體，實現(xiàn)電能與機械能變換的元件，其動態(tài)性能十分復(fù)雜，而且其動態(tài)性能又對全電力系統(tǒng)的動態(tài)性能有極大影響。特點是：穩(wěn)態(tài)運行時，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，其中f為電網(wǎng)頻率，p為電機的極對數(shù)，ns稱為同步轉(zhuǎn)速。若電網(wǎng)的頻率不變，則穩(wěn)態(tài)時同步電機的轉(zhuǎn)速恒為常數(shù)而與負載的大小無關(guān)。同步電機分為同步發(fā)電機和同步電動機?，F(xiàn)代發(fā)電廠中的交流機以同步發(fā)電機為主。
