三相電動(dòng)機(jī)在起動(dòng)時(shí)，起動(dòng)電流很大，可達(dá)到額定電流的4~7倍，很大的起動(dòng)電流，在短時(shí)間內(nèi)會(huì)在線路上造成 </p> <p> 較大的電壓降落，這不僅影響電動(dòng)機(jī)本身的起動(dòng)也會(huì)影響到同**路上的其他電動(dòng)機(jī)和電器設(shè)備的正常工作。 </p> <p> 為此，對大容量電動(dòng)機(jī)且起停頻繁時(shí)，為了限制起動(dòng)電流，必須采取降壓起動(dòng)。所謂降壓起動(dòng)，就是在電動(dòng)機(jī)起 </p> <p> 動(dòng)時(shí)降低加在電動(dòng)機(jī)定子繞組上的電壓，當(dāng)電動(dòng)機(jī)轉(zhuǎn)起來以后，再將加在定子繞組上的電壓恢復(fù)到正常值。由于 </p> <p> 電流與電壓成正比關(guān)系，所以降低起動(dòng)時(shí)的電壓能減小起動(dòng)電流。但是由于電磁轉(zhuǎn)矩與電動(dòng)機(jī)定子繞組端電壓的 </p> <p> 平方成正比，所以電動(dòng)機(jī)在降壓起動(dòng)時(shí)，起動(dòng)轉(zhuǎn)矩相應(yīng)減小，故降壓起動(dòng)適用于空載或輕載下的起動(dòng) </p><p> 電動(dòng)機(jī)在運(yùn)行中的狀況，可以通過電動(dòng)機(jī)電流的大小、溫度的高低、聲響的差異等表面的特征表現(xiàn)出來，因此電工人員可以通過眼、耳、手、鼻，同時(shí)借助儀表、工具加以監(jiān)視和檢測，發(fā)現(xiàn)異常，應(yīng)及時(shí)停機(jī)處理，排除故障。 </p> <p>

</p> <p> 一、通過電能的形式來分 </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)的說法。 </p> <p> 二、按照原理來分類 </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)。聯(lián)創(chuàng)電機(jī)熱情服務(wù)，確保產(chǎn)品質(zhì)量無后顧之憂。日照大型電機(jī)</p><p
