style="text-indent:25px">所謂三相異步電動機(jī)的啟動是指電動機(jī)從接入電源開始轉(zhuǎn)動起，到達(dá)到額定轉(zhuǎn)速為止的這一過程。根據(jù)理論分析和實(shí)際測定，三相異步電動機(jī)啟動瞬間；定子繞組啟動電流很大，可達(dá)額定值的4~7倍。三相異步電動機(jī)為什么會有這么大的啟動電流呢？因?yàn)楫惒诫妱訖C(jī)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(jī)啟動時），從而影響到接在電網(wǎng)上的其它設(shè)備的正常運(yùn)行。使電動機(jī)繞組發(fā)熱，絕緣老化，從而縮短了電動機(jī)的使用壽命。特別是對經(jīng)常需要啟動的電動機(jī)影響較大。啟動瞬間，由于三相異步電動機(jī)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(fù)載轉(zhuǎn)矩則電動機(jī)將無法啟動。綜上所述，三相異步電動機(jī)啟動時的主要缺點(diǎn)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(jī)以誠信為根本，以質(zhì)量服務(wù)求生存。濟(jì)南中型電機(jī)生產(chǎn)廠家</p><p

在過去，傳統(tǒng)的直流電機(jī)的使用覆蓋率非常高，主要是因?yàn)榻^大多數(shù)的電力供給都是直流電。而傳統(tǒng)的直流電機(jī)都是有刷的。有刷電機(jī)指的是靠換向器和電刷的配合來自動完成的電機(jī)，換向器和電刷裝在電機(jī)內(nèi)部。雖然有刷電機(jī)在制作方面技術(shù)純熟，相應(yīng)的配件也比較便宜，但是有刷電機(jī)存在著很多缺點(diǎn)。例如，更換配件程序麻煩、配件使用壽命短、發(fā)熱率高、換向火花大、損耗嚴(yán)重、電磁干擾嚴(yán)重等。所以，盡管有刷電機(jī)存在很多優(yōu)點(diǎn)，但是它還是隨著時代的變化逐漸被無刷電機(jī)所取代。無刷直流電機(jī)由電動機(jī)主體和驅(qū)動器組成，是一種典型的機(jī)電一體化產(chǎn)品。無刷電機(jī)的種類很普遍，并且?guī)缀醪淮嬖谟兴㈦姍C(jī)的所有缺點(diǎn)，無刷電機(jī)磨損小、噪音低、干擾低，可以說無刷電機(jī)相對于有刷電機(jī)具有很大的優(yōu)勢
