編(bian)(bian)碼(ma)(ma)器是(shi)將信(xin)號或數據進行(xing)編(bian)(bian)制、轉(zhuan)(zhuan)(zhuan)換為(wei)可(ke)(ke)用以(yi)通訊、傳(chuan)輸和(he)(he)存儲(chu)的(de)信(xin)號形(xing)式的(de)設備(bei)。在這(zhe)里，編(bian)(bian)碼(ma)(ma)器就是(shi)能夠將電機的(de)轉(zhuan)(zhuan)(zhuan)動信(xin)息（比如轉(zhuan)(zhuan)(zhuan)速、轉(zhuan)(zhuan)(zhuan)動角(jiao)(jiao)度(du)(du)等）轉(zhuan)(zhuan)(zhuan)換為(wei)脈沖信(xin)號的(de)設備(bei)。按照原理可(ke)(ke)分為(wei)（常見的(de)）光(guang)電編(bian)(bian)碼(ma)(ma)器（光(guang)學式）和(he)(he)霍爾編(bian)(bian)碼(ma)(ma)器（磁式）。減速機編(bian)(bian)碼(ma)(ma)器是(shi)可(ke)(ke)以(yi)用來判(pan)斷(duan)旋(xuan)轉(zhuan)(zhuan)(zhuan)速度(du)(du)，和(he)(he)旋(xuan)轉(zhuan)(zhuan)(zhuan)的(de)角(jiao)(jiao)度(du)(du)，主(zhu)要用來判(pan)斷(duan)物件(jian)的(de)速度(du)(du)，和(he)(he)對物件(jian)進行(xing)準(zhun)確定(ding)位。如用編(bian)(bian)碼(ma)(ma)器判(pan)斷(duan)電機旋(xuan)轉(zhuan)(zhuan)(zhuan)速度(du)(du)，用編(bian)(bian)碼(ma)(ma)器判(pan)斷(duan)閥門轉(zhuan)(zhuan)(zhuan)過的(de)角(jiao)(jiao)度(du)(du)，用編(bian)(bian)碼(ma)(ma)器判(pan)斷(duan)輸送帶上物件(jian)移動的(de)距離……編(bian)(bian)碼(ma)(ma)器可(ke)(ke)以(yi)將它判(pan)斷(duan)出的(de)信(xin)息傳(chuan)給，通過plc對信(xin)息處理可以準確(que)的控制(zhi)物件速(su)度(du)，轉速(su)，和準確(que)的定(ding)位！

編碼器直流減速電機、無刷步進減速電機，齒輪箱電機和機械設備的正確安裝與變速箱和驅動電機的正確安裝相同。關鍵是確保減速器的輸出軸與從動軸的同心度一致。直流減速電機的內齒圈與齒輪箱殼體緊密連接，齒圈中心具有由外動力驅動的太陽齒輪，一組三個齒輪在托盤上分為兩組。行星齒輪行星齒輪組依賴輸出軸，內齒圈和太陽齒輪支架在此期間內的浮動;行(xing)星減(jian)速機(ji)在輸入側(ce)動(dong)(dong)(dong)(dong)力(li)驅動(dong)(dong)(dong)(dong)太陽輪(lun)(lun)時，可驅動(dong)(dong)(dong)(dong)行(xing)星齒輪(lun)(lun)轉(zhuan)動(dong)(dong)(dong)(dong)，并跟隨直流(liu)無刷電機(ji)內齒圈運動(dong)(dong)(dong)(dong)軌跡沿(yan)中心(xin)旋轉(zhuan)，行(xing)星的旋轉(zhuan)驅動(dong)(dong)(dong)(dong)與(yu)托盤(pan)相連的動(dong)(dong)(dong)(dong)力(li)輸出軸(zhou)。
