微電子技術(shù)和大功率電力電子技術(shù)的發(fā)展產(chǎn)生了伺服驅(qū)動(dòng)器,它采用數(shù)字信號(hào)處理器(DSP)作為控制核心,實(shí)現(xiàn)比較復(fù)雜的控制算法,達(dá)到數(shù)字化、智能化;其功率器件采用以智能功率模塊(IPM)為核心的驅(qū)動(dòng)電路,同時(shí)具有過電壓、過電流、過熱、欠壓等故障檢測(cè)保護(hù),在主回路中還加入軟啟動(dòng)電路,以減小啟動(dòng)過程中的浪涌電流對(duì)驅(qū)動(dòng)器的沖擊。伺服驅(qū)動(dòng)器的輸出電源是對(duì)交流三相或單相電進(jìn)行整流,得到相應(yīng)的直流電,通過正弦脈寬調(diào)制(SPWM)電壓型逆變器變頻來驅(qū)動(dòng)伺服電機(jī)。這樣伺服電機(jī)接受來自驅(qū)動(dòng)器輸出的脈沖,在脈沖寬度的時(shí)間段內(nèi),電機(jī)實(shí)現(xiàn)位移,一串這樣的脈沖就使得電機(jī)旋轉(zhuǎn)起來,進(jìn)而驅(qū)動(dòng)機(jī)械負(fù)載。由于伺服驅(qū)動(dòng)器輸出電源采用了正弦脈寬調(diào)制技術(shù),這種技術(shù)的特點(diǎn)是輸出的脈沖串不等寬,它可以根據(jù)控制信號(hào)來產(chǎn)生脈寬。如此,伺服電機(jī)的移動(dòng)量就可以隨脈寬的可控特性來選擇、設(shè)定,靈活調(diào)整而未必變更硬件。換句話說,即使相同頻率的脈沖串,由于用戶對(duì)電機(jī)在其對(duì)應(yīng)的脈沖寬度內(nèi)移動(dòng)量的設(shè)定值不一樣,電機(jī)速度乃至負(fù)載側(cè)速度就會(huì)不一樣,它所起的作用與機(jī)械變速齒輪相似,但是卻不像機(jī)械變速齒輪那樣有形,于是有了個(gè)與機(jī)械對(duì)應(yīng)的說法:“電子齒輪”。三菱電機(jī)自動(dòng)化有限公司這樣描述“電子齒輪”的作用:機(jī)械可以以任意倍率的輸入脈沖進(jìn)行移動(dòng)。
