廈門重力通機(ji)(ji)(ji)電(dian)設備(bei)有限公司(si)取得防爆電(dian)機(ji)(ji)(ji)安裝、修(xiu)理(li)資(zi)格(ge)證(zheng)書，承(cheng)接(jie)國(guo)內、外大中型交流、直流、高(gao)低壓(ya)電(dian)機(ji)(ji)(ji)，承(cheng)接(jie)現場(chang)振(zhen)動(dong)檢測，動(dong)平(ping)衡校正；現場(chang)機(ji)(ji)(ji)電(dian)設備(bei)安裝調試、維護、修(xiu)理(li)、施(shi)工；橡塑類開煉機(ji)(ji)(ji)輥筒表面、軸承(cheng)位修(xiu)復，液(ye)壓(ya)缸修(xiu)復，以及各類芯軸修(xiu)復。提(ti)供FAG軸承(cheng)，動(dong)、靜密封(feng)，高(gao)壓(ya)電(dian)機(ji)(ji)(ji)維修(xiu)，電(dian)機(ji)(ji)(ji)配件等機(ji)(ji)(ji)電(dian)產品。

有些電(dian)(dian)(dian)機(ji)在潮氣環境(jing)中閑(xian)置，周圍(wei)的(de)潮氣會使電(dian)(dian)(dian)機(ji)鐵心和(he)繞組絕緣(yuan)表面受潮，凝結成水霧，高壓電(dian)(dian)(dian)機(ji)維修廠(chang)，使電(dian)(dian)(dian)機(ji)絕緣(yuan)電(dian)(dian)(dian)阻降低。再次使用時有可(ke)(ke)能絕緣(yuan)被擊穿。因此(ci)，要求短(duan)期閑(xian)置的(de)電(dian)(dian)(dian)機(ji)要通入電(dian)(dian)(dian)流，靠銅耗辦法加熱(re)繞組，使電(dian)(dian)(dian)機(ji)鐵心和(he)繞組溫度(du)比環境(jing)溫度(du)高出5℃以(yi)(yi)上，繞組絕緣(yuan)就不(bu)會受潮。一(yi)般(ban)選用5%~10%左右(you)的(de)額(e)定電(dian)(dian)(dian)壓，小電(dian)(dian)(dian)機(ji)選用30V左右(you)電(dian)(dian)(dian)壓即可(ke)(ke)。國(guo)外電(dian)(dian)(dian)機(ji)有自帶加熱(re)裝置，可(ke)(ke)以(yi)(yi)靠這個(ge)裝置加熱(re)電(dian)(dian)(dian)機(ji)。

直流無(wu)刷(shua)控制器和(he)直流無(wu)刷(shua)電機怎樣能(neng)倒出正確的(de)相序(xu)？

答：步要(yao)(yao)保證霍爾(er)線的(de)(de)電(dian)(dian)(dian)(dian)源(yuan)線和地線與(yu)控(kong)(kong)制(zhi)器(qi)上相(xiang)對(dui)應的(de)(de)線插好，而(er)三個(ge)電(dian)(dian)(dian)(dian)機霍爾(er)線與(yu)三個(ge)電(dian)(dian)(dian)(dian)機線對(dui)控(kong)(kong)制(zhi)器(qi)的(de)(de)接(jie)法(fa)共有 36 種(zhong)，簡單而(er)笨的(de)(de)方法(fa)是(shi)每種(zhong)狀態逐一試驗。換接(jie)時(shi)可(ke)以不(bu)(bu)(bu)斷(duan)電(dian)(dian)(dian)(dian)進行，但一定要(yao)(yao)仔細，也要(yao)(yao)有一定的(de)(de)次(ci)序。要(yao)(yao)注意每次(ci)擰轉不(bu)(bu)(bu)要(yao)(yao)太大，如果電(dian)(dian)(dian)(dian)機轉動不(bu)(bu)(bu)順利，則這種(zhong)狀態就(jiu)是(shi)不(bu)(bu)(bu)對(dui)的(de)(de)，轉把擰的(de)(de)太大就(jiu)有損(sun)控(kong)(kong)制(zhi)器(qi)，如果出現反轉的(de)(de)情況(kuang)，高壓電(dian)(dian)(dian)(dian)機，在知道控(kong)(kong)制(zhi)器(qi)的(de)(de)相(xiang)序的(de)(de)情況(kuang)下(xia)就(jiu)是(shi)把控(kong)(kong)制(zhi)器(qi)霍爾(er)線 a 、 c 互換，點(dian)擊線 A 相(xiang)與(yu) B 相(xiang)互換，即可(ke)倒為正轉。后驗證接(jie)得正確方法(fa)是(shi)大電(dian)(dian)(dian)(dian)流運轉時(shi)正常。
