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(dá)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(fù)荷狀態(tài)下運轉(zhuǎn)的場合，上海倫茨變頻電機公司。機械特性較硬，上海倫茨變頻電機公司，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，上海倫茨變頻電機公司。交流換向器電動機可劃分單相串勵電動機、交直流兩用電動機和推斥電動機。上海倫茨變頻電機公司</p><div

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(yīng)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(yīng)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(jìn)給傳動方式，由于受自身結(jié)構(gòu)的限制，在進(jìn)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(jìn)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(yīng)快、定位精度高、行程長度不受限制等優(yōu)點。在機床進(jìn)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(jìn)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(dá)到的性能指標(biāo)和優(yōu)點。</p><p style="text-indent:25px">隱極式罩極電動機的定子鐵心與普通單相電動機的鐵心相同，其定子繞組采用分布繞組，主繞組分布于定子槽內(nèi)，罩極繞組不用短路銅環(huán)，而是用較粗的漆包線繞成分布繞組（串聯(lián)后自行短路）嵌裝在定子槽中（約為總槽數(shù)的2/3），起輔助組的作用。主繞組與罩極繞組在空間相距一定的角度。當(dāng)罩極電動機的主繞組通電后，罩極繞組也會產(chǎn)生感應(yīng)電流，使定子磁極被罩極繞組罩住部分的磁通與未罩部分向被罩部分的方向旋轉(zhuǎn)。單相串勵電動機的定子由凸極鐵心和勵磁繞組組成，轉(zhuǎn)子由隱極鐵心、電樞繞組、換向器及轉(zhuǎn)軸等組成。勵磁繞組與電樞繞組之間通過電刷和換向器形成串聯(lián)回路。單相串勵電動機屬于交、直流兩用電動機，它既可以使用交流電源工作，也可以使用直流電源工作。相異步電動機的結(jié)構(gòu)由定子、轉(zhuǎn)子和其它附件組成。</p><div
