關(guān)于plc
plc:可編程邏輯控制器,它采用一類可編程的存儲(chǔ)器,用于其內(nèi)部存儲(chǔ)程序,執(zhí)行邏輯運(yùn)算、順序控制、定時(shí)、計(jì)數(shù)與算術(shù)操作等面向用戶的指令,并通過數(shù)字或模擬式輸入/輸出控制各種類型的機(jī)械或生產(chǎn)過程。
四、關(guān)于伺服驅(qū)動(dòng)器
伺服驅(qū)動(dòng)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(jī)的一種控制器,其作用類似于作用于普通交流馬達(dá),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(dá)進(jìn)行控制,實(shí)現(xiàn)高精度的傳動(dòng)系統(tǒng)定位,目前是傳動(dòng)技術(shù)的高端產(chǎn)品。
五、關(guān)于伺服電機(jī):
伺服電機(jī)(servo motor )是指在伺服系統(tǒng)中控制機(jī)械元件運(yùn)轉(zhuǎn)的發(fā)動(dòng)機(jī),是一種補(bǔ)助馬達(dá)間接變速裝置。
伺服電機(jī)可使控制速度,位置精度非常準(zhǔn)確,可以將電壓信號(hào)轉(zhuǎn)化為轉(zhuǎn)矩和轉(zhuǎn)速以驅(qū)動(dòng)控制對象。伺服電機(jī)轉(zhuǎn)子轉(zhuǎn)速受輸入信號(hào)控制,并能快速反應(yīng),在自動(dòng)控制系統(tǒng)中,用作執(zhí)行元件,且具有機(jī)電時(shí)間常數(shù)小、線性度高、始動(dòng)電壓等特性,可把所收到的電信號(hào)轉(zhuǎn)換成軸上的角位移或角速度輸出。分為直流和交流伺服電動(dòng)機(jī)兩大類,其主要特點(diǎn)是,當(dāng)信號(hào)電壓為零時(shí)無自轉(zhuǎn)現(xiàn)象,轉(zhuǎn)速隨著轉(zhuǎn)矩的增加而勻速下降。
28) 蜜炬紅燭翠袖單,小樓聽雨夜初寒。明朝酒醒繁花落,從此浮生作夢看。
