SPG剎車電機S8R25GDCE SPG獨家代理直流調(diào)速器就是調(diào)節(jié)直流電動機速度的設(shè)備。上端和交流電源連接，下端和直流電動機連接，直流調(diào)速器將交流電轉(zhuǎn)換成兩路輸出直流電源，一路輸入給直流電機勵磁（定子），一路輸入給直流電機電樞（轉(zhuǎn)子），直流調(diào)速器通過控制電樞直流電壓來調(diào)節(jié)直流電動機轉(zhuǎn)速。同時直流電動機給調(diào)速器一個反饋電流，調(diào)速器根據(jù)反饋電流來判斷直流電機的轉(zhuǎn)速情況，必要時修正電樞電壓輸出，一次來再次調(diào)節(jié)電機的轉(zhuǎn)速。

在整個電機行業(yè)中，交流電機占據(jù)著產(chǎn)量的絕大部分。具體數(shù)據(jù)來看，2008年-2016年，我國交流電動機產(chǎn)量增速受宏觀經(jīng)濟影響，波動較為明顯。2016年，我國交流電動機產(chǎn)量為2.78億千瓦，同比下降1.7%。 圖表3：2010-2017年我國交流電動機產(chǎn)量及同比增速（單位：萬千瓦，%）資料來源：國家統(tǒng)計局前瞻產(chǎn)業(yè)研究院整理 無刷電機是電機行業(yè)的“新人”，進入國內(nèi)的歷史并不長，并且價格較有刷電機高，但由于無刷電機優(yōu)勢明顯，發(fā)展勢頭可謂迅猛。進入中國以后，便迅速被家電、汽車、輪船和機械等行業(yè)所青睞，并在各個行業(yè)中占據(jù)一席之地，飛速發(fā)展。據(jù)國家統(tǒng)計局統(tǒng)計，2010年以來，無刷電機行業(yè)收入連年增加，2016年為189.2億元，同比增長22.3%。 圖表4：2010-2017年我國無刷電機行業(yè)銷售收入變化情況（單位：億元，%）資料來源：國家統(tǒng)計局前瞻產(chǎn)業(yè)研究院整理 隨著人們生活水平的提高和現(xiàn)代化生產(chǎn)、辦公自動化的發(fā)展，家用電器、工業(yè)機器人等設(shè)備都越來越趨向于高效率化、小型化及高智能化，作為執(zhí)行元件的重要組成部分，電機必須具有精度高、速度快、效率高等特點，直流無刷電機的應(yīng)用也因此而迅速增長。現(xiàn)階段，雖然各種交流電動機和直流電動機在傳動應(yīng)用中占主導(dǎo)地位，但直流無刷電動機正受到普遍的關(guān)注。未來幾年，我國直流無刷電機的市場前景較為樂觀。 無刷電機行業(yè)未來趨勢。 兩者的優(yōu)缺點對比

直流伺服電機容易實現(xiàn)智能化，其電子換相方式靈活，可以方波換相或正弦波換相。電機免維護不存在碳刷損耗的情況，效率很高，運行溫度低噪音小，電磁輻射很小，長壽命，可用于各種環(huán)境。 交流伺服電機的速度控制特性良好，在整個速度區(qū)內(nèi)可實現(xiàn)平滑控制，幾乎無振蕩，90%以上的高效率，發(fā)熱少，高速控制，高精確度位置控制（取決于編碼器精度），額定運行區(qū)域內(nèi)，可實現(xiàn)恒力矩，慣量低，低噪音，無電刷磨損，免維護（適用于無塵、易爆環(huán)境）。交流伺服電機也是無刷電機，分為同步和異步電機，目前運動控制中一般都用同步電機，其功率范圍大，功率可以做到很大，大慣量，最高轉(zhuǎn)速低，轉(zhuǎn)速隨功率增大而勻速下降，適用于低速平穩(wěn)運行場合。 如果轉(zhuǎn)子繞組中的電流不是由定子旋轉(zhuǎn)磁場感應(yīng)的，而是自己產(chǎn)生的，則轉(zhuǎn)子磁場與定子旋轉(zhuǎn)磁場無關(guān)，而且其磁極方向是固定的，那么根據(jù)同性相斥、異性相吸的原理，定子的旋轉(zhuǎn)磁場就會拉動轉(zhuǎn)子旋轉(zhuǎn)，并且使轉(zhuǎn)子磁場及轉(zhuǎn)子與定子旋轉(zhuǎn)磁場“同步”旋轉(zhuǎn)。這就是同步電動機的工作原理。毫無疑問，同步自然控制起來更方便一點。4、按用途可劃分：驅(qū)動用電動機和控制用電動機。 1）驅(qū)動用電動機可劃分：電動工具（包括鉆孔、拋光、磨光、開槽、切割、擴孔等工具）用電動機、家電（包括洗衣機、電風(fēng)扇、電冰箱、空調(diào)器、錄音機、錄像機、影碟機、吸塵器、照相機、電吹風(fēng)、電動剃須刀等）用電動機及其它通用小型機械設(shè)備（包括各種小型機床、小型機械、醫(yī)療器械、電子儀器等）用電動機。 2）控制用電動機又劃分：步進電動機和伺服電動機等。 5、按轉(zhuǎn)子的結(jié)構(gòu)可劃分：籠型感應(yīng)電動機（舊標(biāo)準(zhǔn)稱為鼠籠型異步電動機）和繞線轉(zhuǎn)子感應(yīng)電動機（舊標(biāo)準(zhǔn)稱為繞線型異步電動機）。 6、按電動車的供能位置以及方式劃分：輪邊電機、輪轂電機和集中式電機
