增量式編碼器(編碼器選型)是將位移轉(zhuǎn)換成周期性的電信號(hào)，再把這個(gè)電信號(hào)轉(zhuǎn)變成計(jì)數(shù)脈沖，用脈沖的個(gè)數(shù)表明位移的巨細(xì)。

增量式編碼器的工作原理：

隨轉(zhuǎn)軸一起轉(zhuǎn)動(dòng)的脈沖碼盤上有均勻刻制的光柵，在碼盤上均勻地分布著若干個(gè)透光區(qū)段和遮光區(qū)段。增量式編碼器沒有固定的起始零點(diǎn)，輸出的是與轉(zhuǎn)角的增量成正比的脈沖，需要用計(jì)數(shù)器來計(jì)脈沖數(shù)。每轉(zhuǎn)過一個(gè)透光區(qū)時(shí)，就發(fā)出一個(gè)脈沖信號(hào)，計(jì)數(shù)器當(dāng)前值加1，計(jì)數(shù)結(jié)果對(duì)應(yīng)于轉(zhuǎn)角的增量。編碼器是把角位移或直線位移轉(zhuǎn)換成電信號(hào)的一種設(shè)備。

前者變成碼盤，后者稱碼尺．依照讀出方法編碼器能夠分為觸摸式和非觸摸式兩種．觸摸式選用電刷輸出，一電刷觸摸導(dǎo)電區(qū)或絕緣區(qū)來表明代碼的狀況是“1"仍是“0"；非觸摸式的承受靈敏元件是光敏元件或磁敏元件，選用光敏元件時(shí)以透光區(qū)和不透光區(qū)來表明代碼的狀況是“1"仍是“0"。

增量式編碼器的特點(diǎn)：

增量式編碼器(電子手輪)色是：非觸摸式的，無沖突和磨損，體積小，重量輕，組織緊湊，裝置便利，保護(hù)簡(jiǎn)略，驅(qū)動(dòng)力矩小，其具有高精度，大量程丈量，反響快，數(shù)字化輸出特色；   

增量式編碼器十分合適測(cè)速度，可無限累加丈量。可是存在零點(diǎn)累計(jì)差錯(cuò)，抗干擾較差，接納設(shè)備的停機(jī)需斷電回憶，開機(jī)應(yīng)找零或參閱位等疑問，這些疑問如選用肯定型編碼器能夠處理。   

內(nèi)置電池技能：有一些編碼器以內(nèi)置電池來防止斷電的信號(hào)丟掉，也有一些編碼器(電子手輪)圈是肯定信號(hào)，而多圈圈數(shù)信號(hào)是內(nèi)置電池與電路用增量計(jì)數(shù)的方法來取得，此為偽肯定型編碼器，其受電池壽數(shù)、電池低溫失效、受振電池觸點(diǎn)不良等因數(shù)影響，而大大下降可靠性。
