style="text-indent:25px">針對高精度光電編碼器轉(zhuǎn)角精度的檢測，提出了一種基于雙頻激光干涉儀的光電編碼器轉(zhuǎn)角精度檢測方法，并研制了相應(yīng)的檢測裝置.該裝置以步進(jìn)電機(jī)為驅(qū)動元件，通過減速機(jī)構(gòu)帶動被檢編碼器和角度基準(zhǔn)旋轉(zhuǎn)，以Renishaw雙頻激光干涉儀為角度基準(zhǔn)檢測儀器，使用RenishawRX10回轉(zhuǎn)軸校準(zhǔn)組件為角度旋轉(zhuǎn)基準(zhǔn)，檢測精度達(dá)1.36″.分別使用該裝置和傳統(tǒng)手動檢測裝置對21bit***式編碼器進(jìn)行精度檢測對比實驗，結(jié)果表明，該裝置是可行的，且在檢測效率，檢測精度上均高于傳統(tǒng)檢測裝置.高精度角度編碼器在永磁同步電機(jī)位置測量中的應(yīng)用有哪些？高精度角度編碼器生產(chǎn)公司</p><p

style="text-indent:25px">高精度角度編碼器工作原理：由一個中心有軸的光電碼盤，其上有環(huán)形通、暗的刻線，有光電發(fā)射和接收設(shè)備件讀取，獲得四組正弦波信號組合成A、B、C、D，每個正弦波相差90度相位差（相對于一個周波為360度），將C、D信號反向，疊加在A、B兩相上，可增強(qiáng)穩(wěn)定信號；另每轉(zhuǎn)輸出一個Z相脈沖以標(biāo)志零位參考位。由于A、B兩相相差90度，可通過比較A相在前還是B相在前，以判別編碼器的正轉(zhuǎn)與反轉(zhuǎn)，通過零位脈沖，可獲得編碼器的零位參考位。編碼器碼盤的材料有玻璃、金屬、塑料，玻璃碼盤是在玻璃上沉積很薄的刻線，其熱穩(wěn)定性好，精度高，金屬碼盤直接以通和不通刻線，不易碎，但由于金屬有一定的厚度，精度就有限制，其熱穩(wěn)定性就要比玻璃的差一個數(shù)量級，塑料碼盤是經(jīng)濟(jì)型的，其成本低，但精度、熱穩(wěn)定性、壽命均要差一些。分辨率—編碼器以每旋轉(zhuǎn)360度提供多少的通或暗刻線稱為分辨率，也稱解析分度、或直接稱多少線，一般在每轉(zhuǎn)分度5~10000線。絕對式角度編碼器費用</p></p><br
