style="text-indent:25px">三相異步電動機的轉(zhuǎn)子繞組作用是切割定子旋轉(zhuǎn)磁場產(chǎn)生感應電動勢及電流，并形成電磁轉(zhuǎn)矩而使電動機旋轉(zhuǎn)。分為鼠籠式轉(zhuǎn)子和繞線式轉(zhuǎn)子。鼠籠式轉(zhuǎn)子是轉(zhuǎn)子繞組由插入轉(zhuǎn)子槽中的多根導條和兩個環(huán)行的端環(huán)組成。若去掉轉(zhuǎn)子鐵心，整個繞組的外形像一個鼠籠，故稱籠型繞組。小型籠型電動機采用鑄鋁轉(zhuǎn)子繞組，對于100KW以上的電動機采用銅條和銅端環(huán)焊接而成。繞線轉(zhuǎn)子繞組與定子繞組相似，也是一個對稱的三相繞組，一般接成星形，三個出線頭接到轉(zhuǎn)軸的三個集流環(huán)上，再通過電刷與外電路聯(lián)接。結(jié)構(gòu)較復雜，故繞線式電動機的應用不如鼠籠式電動機普遍。但通過集流環(huán)和電刷在轉(zhuǎn)子繞組回路中串入附加電阻等元件，用以改善異步電動機的起、制動性能及調(diào)速性能，故在要求一定范圍內(nèi)進行平滑調(diào)速的設(shè)備，如吊車、電梯、空氣壓縮機等上面采用。</p><p 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。減速電機是指減速機和電機（馬達）的集成體。</p><div

style="text-indent:25px">直流無刷電機是同步電機的一種，也就是說電機轉(zhuǎn)子的轉(zhuǎn)速受電機定子旋轉(zhuǎn)磁場的速度及轉(zhuǎn)子極數(shù)影響：在轉(zhuǎn)子極數(shù)固定情況下，改變定子旋轉(zhuǎn)磁場的頻率就可以改變轉(zhuǎn)子的轉(zhuǎn)速。直流無刷電機即是將同步電機加上電子式控制(驅(qū)動器），控制定子旋轉(zhuǎn)磁場的頻率并將電機轉(zhuǎn)子的轉(zhuǎn)速回授至控制中心反復校正，以期達到接近直流電機特性的方式。也就是說直流無刷電機能夠在額定負載范圍內(nèi)當負載變化時仍可以控制電機轉(zhuǎn)子維持一定的轉(zhuǎn)速。直流無刷驅(qū)動器包括電源部及控制部、電源部提供三相電源給電機，控制部則依需求轉(zhuǎn)換輸入電源頻率。電機轉(zhuǎn)子的轉(zhuǎn)速受電機定子旋轉(zhuǎn)磁場的速度及轉(zhuǎn)子極數(shù)影響。電磁制動器哪家好</p><p

style="text-indent:25px">變頻調(diào)速已經(jīng)成為主流的調(diào)速方案，可普遍應用于各行各業(yè)無級變速傳動。特別是隨著變頻器在工業(yè)控制領(lǐng)域內(nèi)日益普遍的應用，變頻電機的使用也日益普遍起來，可以這樣說由于變頻電機在變頻控制方面較普通電機的優(yōu)越性，凡是用到變頻器的地方我們都不難看到變頻電機的身影。機床上傳統(tǒng)的旋轉(zhuǎn)電機 + 滾珠絲杠進給傳動方式，由于受自身結(jié)構(gòu)的限制，在進給速度、加速度、快速定位精度等方面很難有突破性的提高，已無法滿足超高速切削、超精密加工對機床進給系統(tǒng)伺服性能提出的更高要求。直線電機將電能直接轉(zhuǎn)換成直線運動機械能，不需要任何中間轉(zhuǎn)換機構(gòu)的傳動裝置。具有起動推力大、傳動剛度高、動態(tài)響應快、定位精度高、行程長度不受限制等優(yōu)點。在機床進給系統(tǒng)中，采用直線電動機直接驅(qū)動與原旋轉(zhuǎn)電機傳動的較大區(qū)別是取消了從電機到工作臺（拖板）之間的機械傳動環(huán)節(jié)，把機床進給傳動鏈的長度縮短為零，因而這種傳動方式又被稱為“零傳動”。正是由于這種零傳動方式,帶來了原旋轉(zhuǎn)電機驅(qū)動方式無法達到的性能指標和優(yōu)點。電磁制動器哪家好</p><p
