對馬達(dá)的控制通常是速度控制和位移量(選轉(zhuǎn)量)控制，控制方式是隨著馬達(dá)的種類不盡相同。例如步進(jìn)電機(jī)的移動控制，在開環(huán)控制狀態(tài)下，其轉(zhuǎn)動角度(圈數(shù))是隨控制脈沖數(shù)而同步變化，除非失步等特別的情況，否則應(yīng)該可以嚴(yán)格同步移動。除步進(jìn)電機(jī)外，其他電機(jī)的旋轉(zhuǎn)量檢測，如果沒有信號反饋要達(dá)到精密控制是非常困難的?？傊?，電機(jī)轉(zhuǎn)速的快慢控制，如能以控制量表示，并反饋至控制電路，使電機(jī)維持在一定的速度，或停止在一定的位置。一般而言，此旋轉(zhuǎn)反饋量由旋轉(zhuǎn)編碼器來檢測。
內(nèi)密控光電編碼器原理
光電編碼器，是一種通過光電轉(zhuǎn)換將輸出軸上的機(jī)械幾何位移量轉(zhuǎn)換成電脈沖或電子數(shù)字量的傳感器。這是目前應(yīng)用最多的傳感器，光電編碼器是由光柵盤和光電檢測等裝置組成。光柵盤是在一定直徑的圓板上均勻地開設(shè)扇形透光通道。
由于光電編碼器與電動機(jī)同軸，電動機(jī)旋轉(zhuǎn)時(shí)，光柵盤與電動機(jī)同步旋轉(zhuǎn)，經(jīng)發(fā)光二極管等電子元件組成的檢測裝置檢測輸出若干脈沖信號，通過計(jì)算在一定時(shí)間內(nèi)的輸出脈沖的個(gè)數(shù)就能反映當(dāng)前電動機(jī)的轉(zhuǎn)速。此外，為判斷旋轉(zhuǎn)方向，編碼器還可提供電氣相位相差90度的脈沖信號。
內(nèi)密控增量式編碼器
增量式編碼器是直接利用光電轉(zhuǎn)換原理輸出三組方波脈沖A、B和Z相；A、B兩組脈沖相位差90度Z相為每轉(zhuǎn)一個(gè)脈沖，用于基準(zhǔn)點(diǎn)定位。它的優(yōu)點(diǎn)是原理構(gòu)造簡單，機(jī)械平均壽命可在幾萬小時(shí)以上，抗干擾能力強(qiáng)，可靠性高，適合于長距離傳輸。其缺點(diǎn)是無法輸出軸轉(zhuǎn)動的絕對位置信息。
