產(chǎn)品詳情
廣告燈箱無刷直流電機由電機主體和驅(qū)動器組成,是一種典型的機電一體化產(chǎn)品。 電動機的定子繞組多做成三相對稱星形接法,同三相異步電動機十分相似。電動機的轉(zhuǎn)子上粘有已充磁的永磁體,為了檢測電動機轉(zhuǎn)子的極性,在電動機內(nèi)裝有位置傳感器。驅(qū)動器由功率電子器件和集成電路等構(gòu)成,其功能是:接受電動機的啟動、停止、制動信號,以控制電動機的啟動、停止和制動;接受位置傳感器信號和正反轉(zhuǎn)信號,用來控制逆變橋各功率管的通斷,產(chǎn)生連續(xù)轉(zhuǎn)矩;接受速度指令和速度反饋信號,用來控制和調(diào)整轉(zhuǎn)速;提供保護和顯示等等。 由于無刷直流電動機是以自控式運行的,所以不會象變頻調(diào)速下重載啟動的同步電機那樣在轉(zhuǎn)子上另加啟動繞組,也不會在負載突變時產(chǎn)生振蕩和失步。 中小容量的無刷直流電動機的永磁體,現(xiàn)在多采用高磁能積的稀土釹鐵硼(Nd-Fe-B)材料。因此,稀土永磁無刷電機的體積比同容量三相異步電動機縮小了一個機座號。

直流伺服電機分為有刷和無刷電機。
有刷電機成本低,結(jié)構(gòu)簡單,啟動轉(zhuǎn)矩大,調(diào)速范圍寬,控制容易,需要維護,但維護方便(換碳刷),產(chǎn)生電磁干擾,對環(huán)境有要求。因此它可以用于對成本敏感的普通工業(yè)和民用場合。

應(yīng)根據(jù)所篩物料的要求,選擇篩網(wǎng)目數(shù),目數(shù)大的再下層,目數(shù)小的再上層。要確保篩網(wǎng)的目數(shù)選擇正確,如目數(shù)不標準,則會影響生產(chǎn)質(zhì)量。另外,目數(shù)較大的篩網(wǎng)比較輕薄,應(yīng)在底下襯上較小目數(shù)的篩網(wǎng),以此延長篩網(wǎng)的使用壽命。.篩網(wǎng)屬于易損件,在旋振篩使用過程中,應(yīng)定期檢查篩網(wǎng)是否出現(xiàn)斷絲、漏洞、下凹、變形等破損情況,如發(fā)現(xiàn)篩網(wǎng)破損,應(yīng)及時更換,避免出現(xiàn)因篩網(wǎng)破損導(dǎo)致橡膠球掉入物料情況的發(fā)生。篩網(wǎng)托底、橡膠球、密封條使用注意事項篩網(wǎng)托底上放置有橡膠球,因旋振篩的振動,迫使橡膠球在托底上沿圓周方向不斷的彈跳、運動,達到清網(wǎng)的目的,同時也起到了保證篩選產(chǎn)量和精度的效果,在旋振篩的使用過程中,也會出現(xiàn)一定的磨損,應(yīng)定期檢查,必要時給予更換,避免其掉入物料中。

R×1K檔位狀態(tài)下,用萬用表的黑筆觸碰橋堆的任意一個引腳,紅筆則測試另外的幾只引腳。此時如果萬用表顯示為無窮大,則可以判斷黑筆碰觸的引腳為橋堆的輸出正極,如果顯示范圍在4K-1K歐姆,那么,黑筆所碰觸的引腳為負極,紅黑筆正負極判斷后,其余的引腳則是交流輸入。用萬用表判斷數(shù)碼管正負極發(fā)光數(shù)碼管主要是為顯示數(shù)字而設(shè)計,卻使用非常廣泛。那么,在檢修過程中,如何去判斷發(fā)光數(shù)碼管是否損壞?同樣的,這里依然可以使用萬用表檢測,使用的是R×1K檔及R×1K檔。
