卷筒驅動系統(tǒng)和起重機之間是開環(huán)的關系，也就是起重機只發(fā)出卷驅方向指令、加/減速積分時域脈沖信號和接受卷筒狀態(tài)信號。這樣既可以通起重機的PLC實現(xiàn)點對點發(fā)送指令和接受卷筒狀態(tài)信號，也可以通過BP模塊實現(xiàn)通訊。電纜卷筒系統(tǒng)的制動控制可根據(jù)實際工況之需求，對電動機設定不同的抱閘延時時間，這樣能在起重機控制手柄歸零后平穩(wěn)地制動卷盤。制動力矩的設定數(shù)值既能確保在任何條件下防止電纜墜落，又能允許設備在高速運行中發(fā)生緊急停電操作，制動器突然抱閘時，因設備運行慣性可以將電纜安全地拽出卷盤。此安全制動力矩可以在電纜卷筒驅動功率計算書獲得。這就是所謂的“防抱死”特性。由于電纜卷筒的驅動在自動模式下為直接力矩控制模式，馬達的電磁轉矩總是朝著卷繞電纜方向旋轉而不可逆，使得馬達具有了力矩馬達的特性。</span>福建卷筒集成供電系統(tǒng)多穩(wěn)生產(chǎn)的卷盤設備詳解，可以了解一下。</p><div

多穩(wěn)移動供電系統(tǒng)技術開發(fā)（上海）股份有限公司生產(chǎn)的電纜卷筒控制系統(tǒng)是控制大車電纜跟隨大車左右運動進行收放動作，從橋吊主控系統(tǒng)采集的是大車速度信號。大車電纜卷筒系統(tǒng)把卷筒絕對值編碼器數(shù)值轉化為電纜在電纜卷筒上的圈數(shù)，從而根據(jù)電纜圈數(shù)的變化線性給定馬達的輸出力矩。大車電纜卷筒采用力矩控制方式，能確保電纜所受拉力始終處于許可值范圍內(nèi)，從而不會對電纜產(chǎn)生損傷。橋吊有用電纜卷筒的啊？不要動不動就搞編碼器！難道一個5T的門吊繼電接觸器控制就可以了硬是要搞個編碼器PLC就是高科技了就是要裝編碼器的話有沒有實地考察過怎樣用編碼器采集大車速度信號，和電纜卷筒的信號！現(xiàn)在的電纜卷筒在機械上實現(xiàn)了無級變速，只要調整力矩就可一控制電纜的張緊度卷筒的工作原理你知道多少呢？工業(yè)卷筒集成供電系統(tǒng)哪家好</p><p style="text-indent:25px">卷筒集成供電系統(tǒng)的工作原理是什么？解答來了。云南機械智能制造工業(yè)卷筒集成供電系統(tǒng)</p><p> 力矩電機式電纜卷筒力矩電機式電纜卷筒由力矩電機、減速機、滑環(huán)箱體、電纜卷盤、凸輪開關等檢測限位等組成。力矩電機全稱長期堵轉力矩電動機，機械特性較軟，輸出力矩可隨輸出轉速變化而變化，負載增大時，能自動降低轉速增加輸出轉矩，從而保持一定的線速度和張力。力矩電機堵轉性能良好，可以滿足在卷盤啟動及停止時，需要在一段時間內(nèi)保持靜止力矩以使電纜張緊的工況。當電纜卷筒收纜時，力矩電機磁場方向與卷盤旋轉方向相同，輸出力矩通過減速機放大后帶動卷盤收取電纜。隨著卷繞直徑的增大<span style="line-height: 1.5;">電機速度降低，增大輸出轉矩，從而保證收纜線速度與大車運行同步，并保持收纜張力恒定。當電纜卷筒放纜時，力矩電機磁場旋轉方向不變，但與卷盤轉動方向相反，卷盤在電纜的拖拽力作用下反轉，其輸出力矩通過減速器傳遞到卷盤上，形成電纜張力。在此張力的作用下，電纜從卷盤上平穩(wěn)脫離，完成放纜作業(yè)。</span>云南機械智能制造工業(yè)卷筒集成供電系統(tǒng)</p><p
