旋轉編碼器的一般介紹
其(qi)主(zhu)要(yao)有(you)兩(liang)種(zhong)，一(yi)種(zhong)是(shi)增(zeng)量(liang)型(xing)，另(ling)一(yi)種(zhong)是(shi)絕(jue)對(dui)型(xing)。增(zeng)量(liang)型(xing)的(de)特(te)征(zheng)是(shi)隻(zhi)有(you)在(zai)旋(xuan)轉(zhuan)期(qi)間(jian)會(hui)輸(shu)出(chu)對(dui)應(ying)旋(xuan)轉(zhuan)角(jiao)度(du)脈(mai)衝(chong)，停(ting)止(zhi)是(shi)不(bu)會(hui)輸(shu)出(chu)。它(ta)是(shi)利(li)用(yong)計(ji)數(shu)來(lai)測(ce)量(liang)旋(xuan)轉(zhuan)的(de)方(fang)式(shi)；價格比較便宜。絕對型的的特征是不論是否旋轉，可以將對應旋轉角度進行平行輸出的類型，不需要計數器可確認旋轉位置；它還有不受機械的晃動或震動以及開關等電器幹擾的功能，價格貴。在選擇使用時，可參考以下幾點。包括成本、分辨率、外形尺寸、軸負荷及機械壽命、輸出頻率、環境、軸旋轉力矩、輸出回路等等。
