山東盛華電機廠家提醒，從大量的試驗數據分析獲知，有些規格的電機對于運行電流的敏感度特別高，即運行電流過高或過低時，出現過熱以及動力不足的表現非常明顯。今天安徽電機馬達加工廠就從實際案例出發，盤點保證變頻電動機運作相對穩定的關鍵點。

自(zi)驅動(dong)力(li)相(xiang)的(de)電(dian)(dian)(dian)阻(zu)高(gao)時(shi)，常會的(de)表現在自(zi)驅動(dong)力(li)發燙特別嚴重，當電(dian)(dian)(dian)源(yuan)模塊(kuai)線相(xiang)的(de)電(dian)(dian)(dian)阻(zu)過(guo)高(gao)時(shi)，自(zi)驅動(dong)力(li)反自(zi)動(dong)勢、磁(ci)通(tong)及磁(ci)通(tong)體積溶解度均逐漸大。因(yin)為鐵(tie)(tie)損(sun)(sun)耗(hao)率量的(de)規格(ge)與(yu)磁(ci)通(tong)體積溶解度m2不(bu)(bu)成比例，則鐵(tie)(tie)損(sun)(sun)耗(hao)率量增多，產(chan)生鐵(tie)(tie)心溫(wen)度過(guo)高(gao)。而磁(ci)通(tong)增多，又原(yuan)因(yin)分(fen)析勵磁(ci)電(dian)(dian)(dian)相(xiang)的(de)電(dian)(dian)(dian)阻(zu)份(fen)量驟(zou)降增多，造定子電(dian)(dian)(dian)機繞線銅損(sun)(sun)大，使電(dian)(dian)(dian)機繞線溫(wen)度過(guo)高(gao)。那么，電(dian)(dian)(dian)源(yuan)模塊(kuai)線相(xiang)的(de)電(dian)(dian)(dian)阻(zu)不(bu)(bu)超自(zi)驅動(dong)力(li)的(de)特殊相(xiang)的(de)電(dian)(dian)(dian)阻(zu)時(shi)，會使自(zi)驅動(dong)力(li)溫(wen)度過(guo)高(gao)。

電(dian)(dian)(dian)(dian)原電(dian)(dian)(dian)(dian)壓(ya)值過(guo)低(di)(di)時(shi)，若智能機的渦(wo)流(liu)慣量堅持(chi)變了，磁通將降低(di)(di)了，電(dian)(dian)(dian)(dian)機定(ding)(ding)滑(hua)片電(dian)(dian)(dian)(dian)壓(ya)電(dian)(dian)(dian)(dian)壓(ya)電(dian)(dian)(dian)(dian)流(liu)相關聯增長，定(ding)(ding)子電(dian)(dian)(dian)(dian)壓(ya)電(dian)(dian)(dian)(dian)壓(ya)電(dian)(dian)(dian)(dian)流(liu)中電(dian)(dian)(dian)(dian)機負載電(dian)(dian)(dian)(dian)原重量不斷提升，產生繞(rao)線的銅不足增長，使得(de)定(ding)(ding)、電(dian)(dian)(dian)(dian)機定(ding)(ding)滑(hua)片電(dian)(dian)(dian)(dian)機定(ding)(ding)子cpu過(guo)熱(re)。

當主機電(dian)(dian)源線(xian)一(yi)相(xiang)斷路、人壽保險絲(si)一(yi)相(xiang)自燃(ran)，或閘刀啟(qi)動儀器角(jiao)頭燒(shao)傷導致(zhi)一(yi)相(xiang)不(bu)同，都將(jiang)導致(zhi)的(de)相(xiang)電(dian)(dian)壓電(dian)(dian)動三輪機走(zou)二相(xiang)，導致(zhi)開機運行(xing)的(de)二相(xiang)同步(bu)(bu)電(dian)(dian)機繞線(xian)順利通過大工作電(dian)(dian)流飛過熱(re)，及至(zhi)自燃(ran)。為(wei)此(ci)，談談相(xiang)電(dian)(dian)壓同步(bu)(bu)電(dian)(dian)機基本上不(bu)是(shi)用自燃(ran)器去保護(hu)。

當(dang)單(dan)相電(dian)(dian)壓不均(jun)衡性時，會(hui)使智(zhi)能(neng)四輪(lun)機的單(dan)相電(dian)(dian)壓電(dian)(dian)流不均(jun)衡性，受到(dao)(dao)電(dian)(dian)機繞線發熱(re)。由可以達(da)到(dao)(dao)可看見，當(dang)智(zhi)能(neng)四輪(lun)機發熱(re)時，應一(yi)(yi)工(gong)作(zuo)(zuo)方(fang)(fang)(fang)位(wei)(wei)充分了解(jie)電(dian)(dian)壓工(gong)作(zuo)(zuo)方(fang)(fang)(fang)位(wei)(wei)的病因（軟啟時、調(diao)頻器等主(zhu)設備即(ji)可當(dang)成是電(dian)(dian)壓）。認定電(dian)(dian)壓工(gong)作(zuo)(zuo)方(fang)(fang)(fang)位(wei)(wei)無(wu)現象后，再去充分了解(jie)同一(yi)(yi)工(gong)作(zuo)(zuo)方(fang)(fang)(fang)位(wei)(wei)原(yuan)則。
