3.當(dāng)電機(jī)與旋轉(zhuǎn)臺(tái)直傳(減速比=1) 電機(jī)的慣量=系統(tǒng)整個(gè)慣量當(dāng)電機(jī)與旋轉(zhuǎn)臺(tái)(減速比=10) 電機(jī)的慣量 X 100=系統(tǒng)整個(gè)慣量上面這兩具話只告訴你電機(jī)輸出的旋轉(zhuǎn)慣量會(huì)因加上減速機(jī)后所增加的慣量與減速比成平方正比符合 "電機(jī)的慣量 X (5－－-20) >=系統(tǒng)整個(gè)慣量" 選用電機(jī)的慣量與系統(tǒng)整個(gè)慣量才是匹配……
1、所謂慣量匹配，是指電機(jī)轉(zhuǎn)子的慣量與負(fù)載慣量之間的關(guān)系；
2、什么算匹配，這與碰撞理論一致，當(dāng)兩個(gè)慣量相同的物體發(fā)生碰撞時(shí)，則會(huì)發(fā)生一個(gè)物體的動(dòng)量狀態(tài)完全傳遞給另一個(gè)物體，我們稱此種現(xiàn)象為慣量匹配；

為保證鑄造生產(chǎn)能夠順利進(jìn)行、保證鑄造產(chǎn)品的質(zhì)量符合客戶要求，在開展鑄造工作之前，都要進(jìn)行一系列的準(zhǔn)備工作，開工前的檢查工作就是必不可少的。在鋁合金鑄造中應(yīng)該做好以下幾種準(zhǔn)備工作：溫度控制(以轉(zhuǎn)注流程的溫降確定保溫爐、在線除氣箱、過(guò)濾箱以及鑄造流槽前端的各點(diǎn)溫度控制);鋁液轉(zhuǎn)注流程中各對(duì)接口、事故流口的密封及事故箱的到位、容量與干燥情況;轉(zhuǎn)注流槽、鑄造流槽、漏斗(分配袋)、控流筏、打渣箱及工具的加熱和干燥情況;鑄造傳動(dòng)控制系統(tǒng)包括液壓、儀表的運(yùn)行與顯示情況;結(jié)晶器光潔程度、安放位置和引錠頭的位置及干燥情況(包括潤(rùn)滑);冷卻水的調(diào)試檢查及水溫情況;生產(chǎn)合金、規(guī)格的工藝參數(shù)確認(rèn)等等，這些是每個(gè)鑄次不可忽略的工作。新聞:遵義二相步進(jìn)馬達(dá)57HD8401廠家

伺服電機(jī)有幾種制動(dòng)方式
有時(shí)候我們?nèi)菀讓?duì)電磁制動(dòng),再生制動(dòng),動(dòng)態(tài)制動(dòng)的作用混淆,選擇了錯(cuò)誤的配件。以下對(duì)這幾個(gè)概念加以澄清。
動(dòng)態(tài)制動(dòng)器由動(dòng)態(tài)制動(dòng)電阻組成,在故障、急停、電源斷電時(shí)通過(guò)能耗制動(dòng)縮短伺服電機(jī)的機(jī)械進(jìn)給距離.
再生制動(dòng)是指伺服電機(jī)在減速或停車時(shí)將制動(dòng)產(chǎn)生的能量通過(guò)逆變回路反饋到直流母線,經(jīng)阻容回路吸收.
電磁制動(dòng)是通過(guò)機(jī)械裝置鎖住電機(jī)的軸.
