style="text-indent:25px">所謂三相異步電動(dòng)機(jī)的啟動(dòng)是指電動(dòng)機(jī)從接入電源開(kāi)始轉(zhuǎn)動(dòng)起，到達(dá)到額定轉(zhuǎn)速為止的這一過(guò)程。根據(jù)理論分析和實(shí)際測(cè)定，三相異步電動(dòng)機(jī)啟動(dòng)瞬間；定子繞組啟動(dòng)電流很大，可達(dá)額定值的4~7倍。三相異步電動(dòng)機(jī)為什么會(huì)有這么大的啟動(dòng)電流呢？因?yàn)楫惒诫妱?dòng)機(jī)在啟動(dòng)瞬間轉(zhuǎn)子并不能立馬就轉(zhuǎn)動(dòng)起來(lái)，此時(shí)轉(zhuǎn)子電磁感應(yīng)的反電勢(shì)尚未建立起來(lái)，所以外電壓全部加在沒(méi)有反電勢(shì)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(hào)Z表示，是一種對(duì)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(dòng)電流將帶來(lái)以下不良后果：使電網(wǎng)電壓產(chǎn)生波動(dòng)（特別是容量較大的電動(dòng)機(jī)啟動(dòng)時(shí)），從而影響到接在電網(wǎng)上的其它設(shè)備的正常運(yùn)行。使電動(dòng)機(jī)繞組發(fā)熱，絕緣老化，從而縮短了電動(dòng)機(jī)的使用壽命。特別是對(duì)經(jīng)常需要啟動(dòng)的電動(dòng)機(jī)影響較大。啟動(dòng)瞬間，由于三相異步電動(dòng)機(jī)轉(zhuǎn)子電路功率因素較低，啟動(dòng)轉(zhuǎn)矩并不很大。如果啟動(dòng)轉(zhuǎn)矩小于負(fù)載轉(zhuǎn)矩則電動(dòng)機(jī)將無(wú)法啟動(dòng)。綜上所述，三相異步電動(dòng)機(jī)啟動(dòng)時(shí)的主要缺點(diǎn)是啟動(dòng)電流較大。為了減小啟動(dòng)電流，必須采用適當(dāng)?shù)膯?dòng)方法。</p><div

電動(dòng)機(jī)，也叫馬達(dá)，是一種通過(guò)電磁作用實(shí)現(xiàn)電能轉(zhuǎn)換成機(jī)械能的裝置，因?yàn)殡娪袔追N形式，機(jī)械結(jié)構(gòu)也不一樣，磁場(chǎng)形式也會(huì)有不同，電機(jī)本身的用途場(chǎng)所也會(huì)有差異，所以電機(jī)會(huì)有很多種類型，按照不同的標(biāo)準(zhǔn)，也會(huì)有不一樣的叫法和品類了. </p> <p> 一、通過(guò)電能的形式來(lái)分 </p> <p> 1、電有交流和直流兩種形式，所以電機(jī)可以總體分成交流電機(jī)和直流電機(jī)兩大類。 </p> <p> 2、交流電有單相和三相兩種，有單相交流電機(jī)和三相交流電電機(jī) </p> <p> 3、電壓有高低壓等級(jí)之分，所以也有高壓電機(jī)和電壓電機(jī)的說(shuō)法。 </p> <p> 二、按照原理來(lái)分類 </p> <p> 1、根據(jù)轉(zhuǎn)差率不同，可以分成同步電機(jī)和異步電機(jī) </p> <p> 2、同步電機(jī)根據(jù)磁場(chǎng)不一樣，有永磁同步電機(jī)，磁滯同步電機(jī)和磁阻同步電機(jī)。 </p> <p> 3、異步電機(jī)，有感應(yīng)形式的，也有交流換向器形式的。而感應(yīng)形式的有三相異步電機(jī)和罩極異步電機(jī)。交流換向器電機(jī)，還分為推斥電機(jī)，串激電機(jī)。 </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height:
