style="text-indent:25px">定子繞組的主要絕緣項(xiàng)目有以下三種保證繞組的各導(dǎo)電部分與鐵心間的可靠絕緣以及繞組本身間的可靠絕緣。對地絕緣：定子繞組整體與定子鐵心間的絕緣。相間絕緣：各相定子繞組間的絕緣。匝間絕緣：每相定子繞組各線匝間的絕緣。電動(dòng)機(jī)接線盒內(nèi)的接線,電動(dòng)機(jī)接線盒內(nèi)都有一塊接線板，三相繞組的六個(gè)線頭排成上下兩排，并規(guī)定上排三個(gè)接線樁自左至右排列的編號為1（U1）、2（V1）、3（W1），下排三個(gè)接線樁自左至右排列的編號為6（W2）、4（U2）、5（V2），.將三相繞組接成星形接法或三角形接法。凡制造和維修時(shí)均應(yīng)按這個(gè)序號排列。</p><p style="text-indent:25px">由于電機(jī)運(yùn)轉(zhuǎn)時(shí)會產(chǎn)生反電動(dòng)勢而反電動(dòng)勢的大小通常與轉(zhuǎn)速成正比。因此當(dāng)電機(jī)運(yùn)轉(zhuǎn)到一定速度時(shí)，由于反電動(dòng)勢大小與外加電壓大小相同，此時(shí)的速度稱為基速。恒轉(zhuǎn)矩控制：電機(jī)在基速下，進(jìn)行恒轉(zhuǎn)矩控制。此時(shí)電機(jī)的反電動(dòng)勢E與電機(jī)的轉(zhuǎn)速成正比。又電機(jī)的輸出功率與電機(jī)的轉(zhuǎn)矩及轉(zhuǎn)速乘積成正比，因此此時(shí)電機(jī)功率與轉(zhuǎn)速成正比。恒功率控制：當(dāng)電機(jī)超過基速后，通過調(diào)節(jié)電機(jī)勵(lì)磁電流來使電機(jī)的反電動(dòng)勢基本保持恒定，以此提高電機(jī)的轉(zhuǎn)速。此時(shí)，電機(jī)的輸出功率基本保持恒定，但電機(jī)轉(zhuǎn)矩與轉(zhuǎn)速成反比例下降。弱磁控制：當(dāng)電機(jī)轉(zhuǎn)速超過一定數(shù)值后，勵(lì)磁電流已經(jīng)相當(dāng)小，基本不能再調(diào)節(jié)，此時(shí)進(jìn)入弱磁控制階段。交流同步電動(dòng)機(jī)是一種恒速驅(qū)動(dòng)電動(dòng)機(jī)。</p><div
