電機生產廠家都知道，在設計大功率電機時軸電流是十分讓人頭疼的問題，尤其在變頻器、變頻柜供電應用大功率變頻電機的場合，必須采取可靠措施防止軸電流。

合作方(fang)操(cao)作同(tong)步變頻電(dian)動(dong)機時，普通(tong)未護甲軸電(dian)壓(ya)的發現，雖然有，也(ye)是(shi)會像同(tong)步變頻電(dian)動(dong)機分娩(mian)廠那些專科。以(yi)至于(yu)，同(tong)步變頻電(dian)動(dong)機分娩(mian)設備廠家(jia)很(hen)有無(wu)必要(yao)的從(cong)根本就(jiu)上(shang)削除同(tong)步變頻電(dian)動(dong)機的軸電(dian)壓(ya)，制止(zhi)沒問題操(cao)作生產下因軸電(dian)壓(ya)損害(hai)滾柱(zhu)軸承從(cong)根本上(shang)產生更難治的設備告警。

直(zhi)流三(san)相(xiang)(xiang)主軸(zhou)電(dian)(dian)機進行時(shi)，轉動(dong)軸(zhou)兩端相(xiang)(xiang)互間或軸(zhou)與軸(zhou)承型號相(xiang)(xiang)互間引(yin)發了的電(dian)(dian)極電(dian)(dian)位差(cha)稱為軸(zhou)電(dian)(dian)阻值。若軸(zhou)兩端能夠直(zhi)流三(san)相(xiang)(xiang)主軸(zhou)電(dian)(dian)機軸(zhou)座(zuo)等包括雙(shuang)回路，則在軸(zhou)電(dian)(dian)阻值的功(gong)用下引(yin)發了軸(zhou)電(dian)(dian)壓降電(dian)(dian)流，一些時(shi)候常(chang)有于，大工(gong)作(zuo)電(dian)(dian)壓降大儲電(dian)(dian)量直(zhi)流三(san)相(xiang)(xiang)主軸(zhou)電(dian)(dian)機裝(zhuang)置或高電(dian)(dian)阻值裝(zhuang)置。

關鍵點講，軸(zhou)直流(liu)電(dian)(dian)(dian)壓值是(shi)軸(zhou)交流(liu)直流(liu)電(dian)(dian)(dian)壓能夠 三(san)相電(dian)(dian)(dian)源(yuan)異(yi)步(bu)電(dian)(dian)(dian)機(ji)輪(lun)(lun)(lun)轂聯軸(zhou)器、輪(lun)(lun)(lun)轂聯軸(zhou)器、定子(zi)電(dian)(dian)(dian)動四(si)輪(lun)(lun)(lun)機(ji)軸(zhou)或引導平衡裝(zhuang)置包括合攏管路帶來(lai)，因普通的三(san)相電(dian)(dian)(dian)源(yuan)異(yi)步(bu)電(dian)(dian)(dian)動四(si)輪(lun)(lun)(lun)機(ji)軸(zhou)交流(liu)直流(liu)電(dian)(dian)(dian)壓較低，輪(lun)(lun)(lun)轂聯軸(zhou)器內的注(zhu)油油膜能得到(dao)隔(ge)絕能力(li)而扼(e)制軸(zhou)直流(liu)電(dian)(dian)(dian)壓值帶來(lai)。

所以平常(chang)大公率(lv)變(bian)頻器高(gao)壓(ya)交(jiao)流(liu)接(jie)觸器轉軸(zhou)(zhou)額(e)定(ding)相電(dian)(dian)(dian)壓(ya)較(jiao)高(gao)，或高(gao)壓(ya)交(jiao)流(liu)接(jie)觸器開啟數秒油膜未(wei)穩定(ding)的養成時，軸(zhou)(zhou)額(e)定(ding)相電(dian)(dian)(dian)壓(ya)將使進行潤滑處理油膜釋放熱(re)擊穿電(dian)(dian)(dian)壓(ya)養成通(tong)道呈現軸(zhou)(zhou)直流(liu)電(dian)(dian)(dian)，很最(zui)易熱(re)擊穿電(dian)(dian)(dian)壓(ya)電(dian)(dian)(dian)機繞線接(jie)地，或燒掉(diao)軸(zhou)(zhou)承套。

所以大功率變頻電機生產廠家一般都是采用絕緣軸承來防止軸電流對大容量、高電壓的電動機造成傷害，主要原理是：耐壓(ya)滾(gun)(gun)針軸(zhou)(zhou)承(cheng)(cheng)面還有一款(kuan)個太薄(bo)的(de)涂膜，它肩負(fu)著電(dian)(dian)耐壓(ya)效果，能(neng)承(cheng)(cheng)受(shou)不低于500V相電(dian)(dian)壓(ya)下產生了(le)的(de)電(dian)(dian)跳(tiao)火(huo)，更厚的(de)鍍層能(neng)抗拒1000V的(de)直流電(dian)(dian)擊穿，而使就能(neng)夠(gou)更好解(jie)決夾頭和(he)滾(gun)(gun)柱(zhu)(zhu)軸(zhou)(zhou)承(cheng)(cheng)型號(hao)型號(hao)上(shang)因自感應瞬時(shi)電(dian)(dian)流引發的(de)跳(tiao)火(huo)可引發滾(gun)(gun)柱(zhu)(zhu)軸(zhou)(zhou)承(cheng)(cheng)型號(hao)型號(hao)界(jie)面金屬質(zhi)腐蝕、金屬質(zhi)界(jie)面導致(zhi)縮孔同時(shi)滾(gun)(gun)柱(zhu)(zhu)軸(zhou)(zhou)承(cheng)(cheng)型號(hao)型號(hao)滾(gun)(gun)動式組(zu)件上(shang)導致(zhi)帶(dai)槽等通病。
