style="text-indent:25px">不單單是螺旋槳開始運(yùn)動(dòng)的時(shí)候，如果要改變轉(zhuǎn)數(shù)時(shí)，螺旋槳無法馬上響應(yīng)，只能夠慢慢變化。這是由于驅(qū)動(dòng)螺旋槳運(yùn)動(dòng)的油壓受油的黏性、管道阻力所限制。油壓的變化以及螺旋槳轉(zhuǎn)數(shù)滯后，使得用高精度角度編碼器測定轉(zhuǎn)數(shù)進(jìn)行控制變得異常困難。氣壓設(shè)備同理。步進(jìn)電機(jī)向繞組輸入脈沖電流，旋轉(zhuǎn)脈沖對應(yīng)的運(yùn)動(dòng)角度。因此，即便沒有反饋控制，基本上電機(jī)的旋轉(zhuǎn)方向和旋轉(zhuǎn)角度，控制器都可以識(shí)別的。但是如果發(fā)生什么故障的話，用脈沖電流無法運(yùn)動(dòng)，控制器同實(shí)際運(yùn)動(dòng)之間就有存在誤差。高精度角度編碼器由于硬件的損傷，只能進(jìn)行更換。高精角度編碼器批發(fā)價(jià)</p><p

style="text-indent:25px">讀數(shù)系統(tǒng)是基于徑向分度盤的旋轉(zhuǎn)，該分度由交替的透光窗口和不透光窗口構(gòu)成的。此系統(tǒng)全部用一個(gè)紅外光源垂直照射，這樣光就把盤子上的圖像投射到接收工具表面上，該接收工具覆蓋著一層光柵，稱為準(zhǔn)直儀，它具有和光盤相同的窗口。接收工具的工作是感受光盤轉(zhuǎn)動(dòng)所產(chǎn)生的光變化，然后將光變化轉(zhuǎn)換成相應(yīng)的電變化。一般地，旋轉(zhuǎn)高精度角度編碼器也能得到一個(gè)速度信號(hào)，這個(gè)信號(hào)要反饋給變頻器，從而調(diào)節(jié)變頻器的輸出數(shù)據(jù)。故障現(xiàn)象：1、旋轉(zhuǎn)高精度角度編碼器壞（無輸出）時(shí)，變頻器不能正常工作，變得運(yùn)行速度很慢，而且一會(huì)兒變頻器保護(hù)，顯示“PG斷開”聯(lián)合動(dòng)作才能起作用。18位光電單圈SSI編碼器生產(chǎn)公司</p></p><br
