電機是將電能轉(zhuǎn)換成機械能設(shè)備的總稱，也被稱為電動機。電機幾乎可以用在所有的電子設(shè)備，例如手機、家電、PC等。在工業(yè)應(yīng)用中，電動機用于各種驅(qū)動器，可以說，制造工程師和電動機是密不可分的。現(xiàn)階段大多數(shù)的電動機，例如直流（DC）電動機和交流（AC）電動機，都按照弗萊明左手定則及其產(chǎn)生的洛倫茲力（Bli法則）運行。
從目前我國電機行業(yè)的整體來看，基本上可以達到供需平衡，但從局部看，我國中低端電機存在一定的過剩，而在高端電機方面則都處于供不應(yīng)求的狀態(tài)。預(yù)計未來幾年，隨著市場整合的進一步加深、技術(shù)的提高，我國對高端電機產(chǎn)品的依賴程度將會逐漸降低。
2018年度電機行業(yè)產(chǎn)銷平穩(wěn)增長，個別企業(yè)虧損嚴重，導(dǎo)致行業(yè)利潤總額大幅度降低，出口銷量與收入增長幅度變窄；2018年電機原材料價格雖有所波動，但仍處在高位震蕩，成本不斷增長，大大增加了企業(yè)的生產(chǎn)成本，應(yīng)收應(yīng)付賬款全年高位運行，流動資金吃緊，行業(yè)平均綜合經(jīng)濟效益有所下降，而2019年中小型電機企業(yè)則延續(xù)了2018年的變化趨勢。
二、我國伺服電機市場規(guī)模
最近幾年來，我國各領(lǐng)域都取得不錯的發(fā)展成績，伺服電機也在各領(lǐng)域中被廣泛的應(yīng)用起來，并且自身也在不斷創(chuàng)新和完善；2018年我國伺服電機相關(guān)專利公開數(shù)量創(chuàng)新高，數(shù)量為24754項；2019年伺服電機相關(guān)專利公開數(shù)量為8340項，較2018年足足減少了16414項；隨著社會的不斷發(fā)展和進步，伺服驅(qū)動技術(shù)在工業(yè)發(fā)展中的作用越來越大，高速加工技術(shù)和以高速、高精度為基礎(chǔ)的其它技術(shù)的發(fā)展，推動了伺服電機的快速發(fā)展，2014－2020年我國伺服電機市場規(guī)模逐年增加，2019年我國伺服電機市場規(guī)模在62．4億元左右，預(yù)計2020年我國伺服電機市場規(guī)模將達到65．78億元左右。
由于我國伺服電機的發(fā)展相對滯后，因此被歐美和日本企業(yè)占據(jù)了主要的市場份額。自從2013年以來，得益于產(chǎn)業(yè)升級帶來的積極影響，我國伺服電機自主支撐能力已經(jīng)逐漸成型。國內(nèi)規(guī)模較大的伺服電機制造商主要有微光股份、江特電機、寧波韻升等企業(yè)。
2018年微光股份、江特電機、寧波韻升營業(yè)收入分別為：6．47億元、30．17億元、20．26億元；2019年微光股份、江特電機、寧波韻升營業(yè)收入分別為：7．94億元、25．95億元、19．46億元。
從我國市場份額占比來看，2019年微光股份中國伺服電機市場份額占比為0．27％，江特電機伺服電機市場份額占比為5．76％，寧波韻升伺服電機市場份額占比為1．03％，預(yù)計未來市場份額將進一步提升。
