style="text-indent:25px">普異步電機的定子繞組接交流電網(wǎng)，轉(zhuǎn)子繞組不需與其他電源連接。因此，它具有結(jié)構(gòu)簡單，制造、使用和維護方便，運行可靠以及質(zhì)量較小，成本較低等優(yōu)點。異步電機有較高的運行效率和較好的工作特性，從空載到滿載范圍內(nèi)接近恒速運行，能滿足大多數(shù)工農(nóng)業(yè)生產(chǎn)機械的傳動要求。異步電機還便于派生成各種防護型式，以適應(yīng)不同環(huán)境條件的需要。異步電機運行時，必須從電網(wǎng)吸取無功勵磁功率，使電網(wǎng)的功率因數(shù)變壞。因此，對驅(qū)動球磨機、壓縮機等大功率、低轉(zhuǎn)速的機械設(shè)備，常采用同步電機。由于異步電機的轉(zhuǎn)速與其旋轉(zhuǎn)磁場轉(zhuǎn)速有一定的轉(zhuǎn)差關(guān)系，其調(diào)速性能較差（交流換向器電動機除外）。對要求較寬廣和平滑調(diào)速范圍的交通運輸機械、軋機、大型機床、印染及造紙機械等，采用直流電機較經(jīng)濟、方便。lenze三項交流異步電機哪家好直流發(fā)電機的工作原理就是把電樞線圈中感應(yīng)的交變電動勢。</p><div

style="text-indent:25px">三相異步電動機的結(jié)構(gòu)與單相異步電動機相似，其定子鐵心槽中嵌裝三相繞組（有單層鏈?zhǔn)?、單層同心式和單層交叉式三種結(jié)構(gòu)）。定子繞組成接入三相交流電源后，繞組電流產(chǎn)生的旋轉(zhuǎn)磁場，在轉(zhuǎn)子導(dǎo)體中產(chǎn)生感應(yīng)電流，轉(zhuǎn)子在感應(yīng)電流和氣隙旋轉(zhuǎn)磁場的相互作用下，又產(chǎn)生電磁轉(zhuǎn)柜（即異步轉(zhuǎn)柜），使電動機旋轉(zhuǎn)。罩極式電動機是單向交流電動機中較簡單的一種，通常采用籠型斜槽鑄鋁轉(zhuǎn)子。它根據(jù)定子外形結(jié)構(gòu)的不同，又分為凸極式罩極電動機隱極式罩極電動機。凸極式罩極電動機的定子鐵心外形為方形、矩形或圓形的磁場框架，磁極凸出，每個磁極上均有1個或多個起輔助作用的短路銅環(huán)，即罩極繞組。凸極磁極上的集中繞組作為主繞組。</p><p style="text-indent:25px">變頻調(diào)速的優(yōu)點是調(diào)速功率高，歸于高效調(diào)速方法。這是因為在頻率改變后，電動機仍在同步轉(zhuǎn)速鄰近運轉(zhuǎn)，基本堅持額外轉(zhuǎn)差。只是在變頻設(shè)備體系中會發(fā)生變流損失，以及因為高次諧波的影響，電動機的損耗增加，然后功率有所下降。調(diào)速規(guī)模寬，一般可達20:1，并在整個調(diào)速規(guī)模內(nèi)具有高的調(diào)速功率。所以變頻調(diào)速適用于調(diào)速規(guī)模寬，且常常處于低負荷狀態(tài)下運轉(zhuǎn)的場合。機械特性較硬，在無自動控制時，轉(zhuǎn)速改變率在5%以下；當(dāng)選用自動控制時，能做高精度運轉(zhuǎn)，把轉(zhuǎn)速波動率控制在0.5%|~1%左右。直流電機的勵磁方式是指對勵磁繞組如何供電、產(chǎn)生勵磁磁通勢而建立主磁場的問題。</p><div
