電磁調(diào)速電機(jī)由籠型電機(jī)、電磁轉(zhuǎn)差離合器和直流勵(lì)磁電源（控制器） 三部分組成。
直流勵(lì)磁電源功率較小， 通常由單相半波或全波晶閘管整流器組成， 改變晶閘管的導(dǎo)通角，可以改變勵(lì)磁電流的大小。
電磁轉(zhuǎn)差離合器由電樞、磁 極和勵(lì)磁繞組三部分組成。電樞和后者沒有機(jī)械聯(lián)系，都能自由轉(zhuǎn)動(dòng)。電樞與電機(jī)轉(zhuǎn)子同軸聯(lián)接稱主動(dòng)部分，由電機(jī)帶動(dòng)；磁極用聯(lián)軸節(jié)與負(fù)載軸對(duì)接稱從動(dòng)部分。當(dāng)電樞與磁極均為靜止時(shí)，如勵(lì)磁繞組通以直流，則沿氣隙圓周表面將 形成若干對(duì) N、S 極替的磁極，其磁通經(jīng)過電樞。
當(dāng)電樞隨拖動(dòng)電機(jī)旋轉(zhuǎn)時(shí)，由于電樞與磁極間相對(duì)運(yùn)動(dòng)，因而使電樞感應(yīng)產(chǎn)生渦流，此渦流與磁通相互作用產(chǎn)生轉(zhuǎn)矩，帶動(dòng)有磁極的轉(zhuǎn)子按同一方向旋轉(zhuǎn)，但其轉(zhuǎn)速恒低于電樞的轉(zhuǎn)速 N1，這是一種轉(zhuǎn)差調(diào)速方式，變動(dòng)轉(zhuǎn)差離合器的直流勵(lì)磁電流，便可改變離合器的輸出轉(zhuǎn)矩和轉(zhuǎn)速。
電磁調(diào)速電機(jī)的調(diào)速特點(diǎn)：
1、裝置結(jié)構(gòu)及控制線路簡單、運(yùn)行可靠、維修方便；
2、調(diào)速平滑、無級(jí)調(diào)速；
3、對(duì)電網(wǎng)無諧影響；
4、速度失大、效率低。
5、本方法適用于中、小功率，要求平滑動(dòng)、短時(shí)低速運(yùn)行的生產(chǎn)機(jī)械。

1、熱平衡校核
通用減速機(jī)的許用熱功率值是在特定工況條件下（一般環(huán)境溫度20℃，每小時(shí)100％，連續(xù)運(yùn)轉(zhuǎn)、功率利用率100％），按潤滑油允許的平衡溫度（一般為85℃）確定的。
2、按機(jī)械功率或轉(zhuǎn)矩選擇規(guī)格（強(qiáng)度校核）
通用減速器和專用減速機(jī)型號(hào)（如電爐減速機(jī)）設(shè)計(jì)選型方法的不同在于，前者適用于各個(gè)行業(yè)，但減速只能按一種特定的工況條件設(shè)計(jì)，故選用時(shí)用戶需根據(jù)各自的要求考慮不同的修正系數(shù)，工廠應(yīng)該按實(shí)際選用的電動(dòng)機(jī)功率（不是減速器的額定功率）打銘牌；后者按用戶的專用條件設(shè)計(jì)，該考慮的系數(shù)，設(shè)計(jì)時(shí)一般已作考慮，選用時(shí)只要滿足使用功率小于等于減速器的額定功率即可，方法相對(duì)簡單。
3、校核軸伸部位承受的徑向載荷
通用減速器常常須對(duì)輸入軸、輸出軸軸伸中間部位允許承受的徑向載荷給予限制，應(yīng)予校核，超過時(shí)應(yīng)向制造廠提出加粗軸徑和加大軸承等要求。

2.很多客戶反映在伺服電機(jī)系統(tǒng)選型及調(diào)試中，常常會(huì)碰到慣量問題！那么到底什么是“慣量匹配”呢？
1.根據(jù)牛頓第二定律：“進(jìn)給系統(tǒng)所需力矩T=系統(tǒng)傳動(dòng)慣量J×角加速度θ角加速度θ影響系統(tǒng)的動(dòng)態(tài)特性，θ越小，則由控制器發(fā)出指令到系統(tǒng)執(zhí)行完畢的時(shí)間越長，系統(tǒng)反應(yīng)越慢。如果θ變化，則系統(tǒng)反應(yīng)將忽快忽慢，影響加工精度。由于馬達(dá)選定后輸出T值不變，如果希望θ的變化小，則J應(yīng)該盡量小。
2.進(jìn)給軸的總慣量“J＝伺服電機(jī)的旋轉(zhuǎn)慣性動(dòng)量JM＋電機(jī)軸換算的負(fù)載慣性動(dòng)量JL負(fù)載慣量JL由（以工具機(jī)為例）工作臺(tái)及上面裝的夾具和工件、螺桿、聯(lián)軸器等直線和旋轉(zhuǎn)運(yùn)動(dòng)件的慣量折合到馬達(dá)軸上的慣量組成。JM為伺服電機(jī)轉(zhuǎn)子慣量，伺服電機(jī)選定后，此值就為定值，而JL則隨工件等負(fù)載改變而變化。如果希望J變化率小些，則使JL所占比例小些。這就是通俗意義上的“慣量匹配”。
