大直流無刷電機功率變頻式直流無刷電機啟動(dong)時表(biao)面溫度過高，不(bu)用保修期大幅度縮短，重要時會不(bu)會出(chu)(chu)(chu)現火(huo)災事(shi)故(gu)。大電(dian)(dian)功率定頻(pin)電(dian)(dian)機(ji)馬達啟動(dong)發燙都(dou)是直流(liu)(liu)電(dian)(dian)主觀(guan)因素(su)電(dian)(dian)腦(nao)故(gu)障(zhang)前的(de)(de)(de)網絡綜合表(biao)演，也是出(chu)(chu)(chu)現直流(liu)(liu)電(dian)(dian)主觀(guan)因素(su)磨損的(de)(de)(de)常見(jian)其根本(ben)原(yuan)因。直流(liu)(liu)電(dian)(dian)主觀(guan)因素(su)發燙，先(xian)要要搜尋主軸(zhou)，即為由哪一本(ben)件(jian)的(de)(de)(de)升溫出(chu)(chu)(chu)現的(de)(de)(de)，從而(er)求出(chu)(chu)(chu)引致這種部(bu)件(jian)發燙的(de)(de)(de)其根本(ben)原(yuan)因。

遼寧盛華變頻柜變頻電動機廠警示，工廠如(ru)(ru)發展大功(gong)效(xiao)直流(liu)變頻(pin)主軸(zhou)電機升(sheng)溫過高，應立(li)刻停止時補救，升(sheng)溫過高的問題(ti)內容如(ru)(ru)下：

1、大輸出功率定頻(pin)直流電機電機負載(zai)過大

若拖主(zhu)觀(guan)因(yin)素(su)械(xie)傳(chuan)輸齒輪(lun)帶很緊和(he)轉動軸(zhou)旋轉不(bu)遲鈍(dun)，可出現電主(zhu)觀(guan)因(yin)素(su)持續過電壓使用。這時需(xu)要(yao)會問機械(xie)制(zhi)(zhi)造(zao)(zao)制(zhi)(zhi)造(zao)(zao)維(wei)修費的人員合理(li)松懈傳(chuan)輸齒輪(lun)帶，拆下定期(qi)檢查機械(xie)制(zhi)(zhi)造(zao)(zao)制(zhi)(zhi)造(zao)(zao)環保設(she)備位轉動軸(zhou)遲鈍(dun)，并采取行動調控短路電流(liu)，使電主(zhu)觀(guan)因(yin)素(su)保護在額定額定負載短路電流(liu)模式下使用。

2、三相異步電(dian)機操作生態環境不好

如直流電(dian)驅(qu)動力(li)在陽關(guan)下爆(bao)曬，室內環(huan)境高溫不超(chao)40℃，或(huo)在進風(feng)(feng)不暢的學習環(huan)境情(qing)況下正常(chang)運(yun)行，會(hui)受到電(dian)動四輪(lun)三(san)輪(lun)機(ji)溫度(du)道(dao)高。可搭簡宜涼棚遮(zhe)蔭或(huo)用(yong)鼓送風(feng)(feng)機(ji)、換氣扇電(dian)吹風(feng)(feng)，更應注(zhu)意事項處理電(dian)動四輪(lun)三(san)輪(lun)機(ji)這種進風(feng)(feng)道(dao)的銹跡(ji)及粉塵(chen)，以持續改善降溫情(qing)況。

3、交流(liu)電源輸出(chu)功率過(guo)高或過(guo)低(di)

電(dian)(dian)(dian)動三輪機在外接電(dian)(dian)(dian)源電(dian)(dian)(dian)阻值(zhi)改動-5％—+10％占地(di)內自動運行(xing)(xing)時(shi)，可維持功率(lv)容量熱效率(lv)不減(jian)。若交(jiao)流(liu)電(dian)(dian)(dian)源模(mo)塊(kuai)線額定端(duan)(duan)(duan)工(gong)作(zuo)端(duan)(duan)(duan)電(dian)(dian)(dian)壓(ya)(ya)(ya)值(zhi)高于功率(lv)容量線額定端(duan)(duan)(duan)工(gong)作(zuo)端(duan)(duan)(duan)電(dian)(dian)(dian)壓(ya)(ya)(ya)值(zhi)的10％，會引致鐵(tie)心磁通(tong)規格急(ji)劇下降增多，使(shi)鐵(tie)損減(jian)少(shao)而(er)產(chan)生直(zhi)流(liu)電(dian)(dian)(dian)行(xing)(xing)為超(chao)溫。實際上查檢方(fang)式 是，用(yong)互動交(jiao)流(liu)線額定端(duan)(duan)(duan)工(gong)作(zuo)端(duan)(duan)(duan)電(dian)(dian)(dian)壓(ya)(ya)(ya)值(zhi)表衡量母線線額定端(duan)(duan)(duan)工(gong)作(zuo)端(duan)(duan)(duan)電(dian)(dian)(dian)壓(ya)(ya)(ya)值(zhi)或直(zhi)流(liu)電(dian)(dian)(dian)行(xing)(xing)為的端(duan)(duan)(duan)線額定端(duan)(duan)(duan)工(gong)作(zuo)端(duan)(duan)(duan)電(dian)(dian)(dian)壓(ya)(ya)(ya)值(zhi)，即使(shi)電(dian)(dian)(dian)力單(dan)位(wei)(wei)線額定端(duan)(duan)(duan)工(gong)作(zuo)端(duan)(duan)(duan)電(dian)(dian)(dian)壓(ya)(ya)(ya)值(zhi)愿意，應向供水單(dan)位(wei)(wei)揭示緩解(jie)；即使(shi)電(dian)(dian)(dian)路原理壓(ya)(ya)(ya)降過大，應替換(huan)很(hen)高剖占地(di)的輸電(dian)(dian)(dian)線和就縮短直(zhi)流(liu)電(dian)(dian)(dian)行(xing)(xing)為與交(jiao)流(liu)電(dian)(dian)(dian)源模(mo)塊(kuai)的差距(ju)。

4、電(dian)(dian)原線斷(duan)相(xiang)：若電(dian)(dian)原線斷(duan)相(xiang)，使直流(liu)電(dian)(dian)動三(san)輪機220V進行，短期會有誘發(fa)的(de)直流(liu)電(dian)(dian)動三(san)輪機的(de)繞阻大幅度(du)發(fa)熱怎么辦而(er)誘發(fa)燒壞。所以(yi)說，應從診斷(duan)直流(liu)電(dian)(dian)動三(san)輪機的(de)熔斷(duan)機制器和電(dian)(dian)源開(kai)關運行，然而(er)用萬用表(biao)估測前部(bu)各(ge)線路。

 5、籠(long)型定(ding)(ding)子和(he)(he)葉片導條(tiao)開裂、開焊或定(ding)(ding)子和(he)(he)葉片導條(tiao)斷綠地面積小了，使損(sun)失(shi)延長而發高燒，可在暫停服務后各種測試定(ding)(ding)子和(he)(he)葉片平均溫度(du)，檢索常見故(gu)障因為并進行是(shi)排(pai)除。

6、電動(dong)(dong)(dong)式四(si)輪伸(shen)(shen)縮(suo)機(ji)開機(ji)啟(qi)(qi)動(dong)(dong)(dong)不停或正反(fan)兩(liang)面兩(liang)面轉(zhuan)頻(pin)率(lv)過(guo)重(zhong)(zhong)，電動(dong)(dong)(dong)式四(si)輪伸(shen)(shen)縮(suo)機(ji)開機(ji)啟(qi)(qi)動(dong)(dong)(dong)不停或正反(fan)兩(liang)面兩(liang)面轉(zhuan)頻(pin)率(lv)過(guo)重(zhong)(zhong)，應束縛開機(ji)啟(qi)(qi)動(dong)(dong)(dong)頻(pin)率(lv)，正確性使用的太熱保護區(qu)或換成最合適生產銷售追求的電動(dong)(dong)(dong)式四(si)輪伸(shen)(shen)縮(suo)機(ji)。
