開環(huán)控制數(shù)控系統(tǒng)
這類數(shù)控系統(tǒng)不帶檢測裝置,也無反饋電路,以步進電動機為驅(qū)動元件。CNC裝置輸出的進給指令(多為脈沖接口)經(jīng)驅(qū)動電路進行功率放大,轉(zhuǎn)換為控制步進電動機各定子繞組依此通電/斷電的電流脈沖信號,驅(qū)動步進電動機轉(zhuǎn)動,再經(jīng)機床傳動機構(gòu)(齒輪箱,絲杠等)帶動工作臺移動。這種方式控制簡單,價格比較低廉,從70年始,被廣泛應(yīng)用于經(jīng)濟型數(shù)控機床中。
伺服驅(qū)動器(servo drives)又稱為“伺服控制器”、“伺服放大器”,是用來控制伺服電機的一種控制器,其作用類似于變頻器作用于普通交流馬達,屬于伺服系統(tǒng)的一部分,主要應(yīng)用于高精度的定位系統(tǒng)。一般是通過位置、速度和力矩三種方式對伺服馬達進行控制,實現(xiàn)高精度的傳動系統(tǒng)定位,目前是傳動技術(shù)的產(chǎn)品。
歲月如風(fēng),又到寒冬。我喜歡這種不期而至的問候,讓它抹去被忽略了的牽掛,讓它帶去我的思念,愿你看到這信息時,會在這冬季擁有一絲溫暖和感動!
