style="text-indent:25px">按轉(zhuǎn)子的結(jié)構(gòu)可劃分籠型感應(yīng)電動機（舊標準稱為鼠籠型異步電動機）和繞線轉(zhuǎn)子感應(yīng)電動機（舊標準稱為繞線型異步電動機）。按運轉(zhuǎn)速度可劃分高速電動機、低速電動機、恒速電動機、調(diào)速電動機。低速電動機又分為齒輪減速電動機、電磁減速電動機、力矩電動機和爪極同步電動機等。調(diào)速電動機除可分為有級恒速電動機、無級恒速電動機、有級變速電動機和無級變速電動機外，還可分為電磁調(diào)速電動機、直流調(diào)速電動機、PWM變頻調(diào)速電動機和開關(guān)磁阻調(diào)速電動機。異步電動機的轉(zhuǎn)子轉(zhuǎn)速總是略低于旋轉(zhuǎn)磁場的同步轉(zhuǎn)速。同步電動機的轉(zhuǎn)子轉(zhuǎn)速與負載大小無關(guān)而始終保持為同步轉(zhuǎn)速。起重機制動器報價無刷直流電動機是采用半導(dǎo)體開關(guān)器件來實現(xiàn)電子換向的。</p><div

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。</p><p style="text-indent:25px">高速響應(yīng)由于系統(tǒng)中直接取消了一些響應(yīng)時間常數(shù)較大的機械傳動件（如絲杠等），使整個閉環(huán)控制系統(tǒng)動態(tài)響應(yīng)性能較大提高，反應(yīng)異常靈敏快捷。直線驅(qū)動系統(tǒng)取消了由于絲杠等機械機構(gòu)產(chǎn)生的傳動間隙和誤差，減少了插補運動時因傳動系統(tǒng)滯后帶來的追蹤誤差。通過直線位置檢測反饋控制，即可較大提高機床的定位精度。動剛度高由于“直接驅(qū)動”，避免了啟動、變速和換向時因中間傳動環(huán)節(jié)的彈性變形、摩擦磨損和反向間隙造成的運動滯后現(xiàn)象，同時也提高了其傳動剛度。由于直線電動機較早主要用于磁懸浮列車，所以用在機床進給驅(qū)動中，要滿足其超高速切削的較大進給速度當(dāng)然是沒有問題的。也由于上述“零傳動”的高速響應(yīng)性，使其加減速過程較大縮短。以實現(xiàn)起動時瞬間達到高速，高速運行時又能瞬間準停。可獲得較高的加速度，一般可達2～10g(g=9.8m/s2），而滾珠絲杠傳動的較大加速度一般只有0.1～0.5g。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">當(dāng)子繞組接通電源后電動機以異步電動機原理起動動轉(zhuǎn)，加速運轉(zhuǎn)至同步轉(zhuǎn)速時，由轉(zhuǎn)子永磁磁場和定子磁場產(chǎn)生的同步電磁轉(zhuǎn)矩（由轉(zhuǎn)子永磁磁場產(chǎn)生的電磁轉(zhuǎn)矩與定子磁場產(chǎn)生的磁阻轉(zhuǎn)矩合成）將轉(zhuǎn)子牽入同步，電動機進入同步運行。磁阻同步電動機磁阻同步電動機也稱反應(yīng)式同步電動機，是利用轉(zhuǎn)子交軸和直軸磁阻不等而產(chǎn)生磁阻轉(zhuǎn)矩的同步電動機，其定子與異步電動機的定子結(jié)構(gòu)類似，只是轉(zhuǎn)子結(jié)構(gòu)不同。同籠型異步電動機演變來的，為了使電動機能產(chǎn)生異步起動轉(zhuǎn)矩，轉(zhuǎn)子還設(shè)有籠型鑄鋁繞阻。轉(zhuǎn)子上開設(shè)有與定子極數(shù)相對應(yīng)的反應(yīng)槽（*有凸極部分的作用，無勵磁繞組和很久磁鐵），用來產(chǎn)生磁阻同步轉(zhuǎn)矩。根據(jù)轉(zhuǎn)子上反應(yīng)槽的結(jié)構(gòu)的不同，可分為內(nèi)反應(yīng)式轉(zhuǎn)子、外反應(yīng)式轉(zhuǎn)子和內(nèi)外反應(yīng)式轉(zhuǎn)子，其中，外反應(yīng)式轉(zhuǎn)子反應(yīng)槽開地轉(zhuǎn)子外圓，使其直軸與交軸方向氣隙不等。內(nèi)反應(yīng)式轉(zhuǎn)子的內(nèi)部開有溝槽，使交軸方向磁通受阻，磁阻加大。內(nèi)外反應(yīng)式轉(zhuǎn)子結(jié)合以上兩種轉(zhuǎn)子的結(jié)構(gòu)特點，直軸與交軸差別較大，使電動機的力能較大。磁阻同步電動機也分為單相電容運轉(zhuǎn)式、單相電容起動式、單相雙值電容式等多種類型。串勵直流電機的勵磁繞組與電樞繞組串聯(lián)后，再接于直流電源。起重機制動器報價</p><p style="text-indent:25px">交流同步電動機是一種恒速驅(qū)動電動機。厚譜低壓直流伺服電機哪家好</p><p style="text-indent:25px">力矩電動機具有低轉(zhuǎn)速和大力矩的特點。一般在紡織工業(yè)中經(jīng)常使用交流力矩電動機，其工作原理和結(jié)構(gòu)和單相異步電動機的相同。開關(guān)磁阻電動機是一種新型調(diào)速電動機，結(jié)構(gòu)極其簡單且堅固，成本低，調(diào)速性能優(yōu)異，是傳統(tǒng)控制電動機強有力競爭者，具有強大的市場潛力。無刷直流電動機的機械特性和調(diào)節(jié)特性的線性度好，調(diào)速范圍廣，壽命長，維護方便噪聲小，不存在因電刷而引起的一系列問題，所以這種電動機在控制系統(tǒng)中有很大的應(yīng)用。直流電動機具有調(diào)速性能好、起動容易、能夠載重起動等優(yōu)點，所以直流電動機的應(yīng)用仍然很普遍，尤其在可控硅直流電源出現(xiàn)以后。厚譜低壓直流伺服電機哪家好</p><p
