例(li)式(shi)電(dian)(dian)動(dong)執(zhi)行(xing)機(ji)構(gou)是一個(ge)以(yi)兩相伺(si)服(fu)電(dian)(dian)動(dong)機(ji)為(wei)動(dong)力源的(de)(de)(de)位(wei)置(zhi)(zhi)伺(si)服(fu)機(ji)構(gou)，由電(dian)(dian)動(dong)伺(si)服(fu)放大器(qi)(qi)(qi)和積分式(shi)電(dian)(dian)動(dong)執(zhi)行(xing)機(ji)構(gou)組(zu)成，對于(yu)比例(li)式(shi)電(dian)(dian)動(dong)執(zhi)行(xing)機(ji)構(gou)（當電(dian)(dian)動(dong)操作器(qi)(qi)(qi)為(wei)“自動(dong)"工(gong)作狀態或未接入電(dian)(dian)動(dong)操作器(qi)(qi)(qi)時），當伺(si)服(fu)放大器(qi)(qi)(qi)的(de)(de)(de)輸(shu)入端有控制信(xin)(xin)(xin)(xin)號(hao)(hao)輸(shu)入時，此(ci)信(xin)(xin)(xin)(xin)號(hao)(hao)與(yu)來自位(wei)置(zhi)(zhi)發送器(qi)(qi)(qi)的(de)(de)(de)位(wei)置(zhi)(zhi)反(fan)饋信(xin)(xin)(xin)(xin)號(hao)(hao)進(jin)行(xing)比較，比較厚的(de)(de)(de)信(xin)(xin)(xin)(xin)號(hao)(hao)偏(pian)差經過放大，使(shi)功率級導通相應回路以(yi)驅動(dong)兩相伺(si)服(fu)電(dian)(dian)動(dong)機(ji)轉動(dong)，使(shi)減速器(qi)(qi)(qi)的(de)(de)(de)輸(shu)出軸(zhou)朝著減小(xiao)這一偏(pian)差方向轉動(dong)（位(wei)置(zhi)(zhi)發送器(qi)(qi)(qi)不斷地將輸(shu)出軸(zhou)的(de)(de)(de)實(shi)際位(wei)置(zhi)(zhi)轉變(bian)為(wei)電(dian)(dian)信(xin)(xin)(xin)(xin)號(hao)(hao)--位(wei)置(zhi)(zhi)反(fan)饋信(xin)(xin)(xin)(xin)號(hao)(hao)回伺(si)服(fu)放大器(qi)(qi)(qi)）直到信(xin)(xin)(xin)(xin)號(hao)(hao)偏(pian)差小(xiao)于(yu)死區(qu)為(wei)止，此(ci)時輸(shu)出軸(zhou)就(jiu)穩定在與(yu)輸(shu)入信(xin)(xin)(xin)(xin)號(hao)(hao)相應的(de)(de)(de)位(wei)置(zhi)(zhi)上(shang)。輸(shu)出軸(zhou)的(de)(de)(de)行(xing)程與(yu)輸(shu)入信(xin)(xin)(xin)(xin)號(hao)(hao)成比例(li)關系。

三、使用說(shuo)明

積分(fen)(fen)式(shi)(shi)電(dian)(dian)動(dong)執(zhi)(zhi)行機構由兩相伺(si)(si)服(fu)電(dian)(dian)動(dong)機、減速器(qi)(qi)和位置(zhi)發送器(qi)(qi)組成(cheng)(cheng)。對于積分(fen)(fen)式(shi)(shi)執(zhi)(zhi)行機構，置(zhi)電(dian)(dian)動(dong)操(cao)作器(qi)(qi)為“手動(dong)"狀態，按(an)(an)下電(dian)(dian)動(dong)操(cao)作器(qi)(qi)的“關"或(huo)“開"按(an)(an)鈕(niu)(niu)，伺(si)(si)服(fu)電(dian)(dian)動(dong)機通電(dian)(dian)旋轉(zhuan)(zhuan)(zhuan)，減速器(qi)(qi)的輸出軸朝著“關"或(huo)“開"的方向轉(zhuan)(zhuan)(zhuan)動(dong)，位置(zhi)發送器(qi)(qi)將輸出軸的實際(ji)位置(zhi)不(bu)斷地轉(zhuan)(zhuan)(zhuan)變為電(dian)(dian)信(xin)號(hao)--位置(zhi)反饋信(xin)號(hao)送回電(dian)(dian)動(dong)操(cao)作器(qi)(qi)的閥位開度(du)表，當閥位開度(du)表的反饋信(xin)號(hao)顯示(shi)輸出軸已經轉(zhuan)(zhuan)(zhuan)動(dong)到需要的位置(zhi)時，放開電(dian)(dian)動(dong)操(cao)作器(qi)(qi)的按(an)(an)鈕(niu)(niu)，伺(si)(si)服(fu)電(dian)(dian)動(dong)機斷電(dian)(dian)停(ting)(ting)轉(zhuan)(zhuan)(zhuan)，輸出軸停(ting)(ting)止轉(zhuan)(zhuan)(zhuan)動(dong)，輸出軸的轉(zhuan)(zhuan)(zhuan)動(dong)量與(yu)通電(dian)(dian)時間成(cheng)(cheng)積分(fen)(fen)關系。
