電機星三角啟動(dòng)的問(wèn)題！首先描述一下問(wèn)題

工廠(chǎng)改造安裝，有全新的也有舊的電機。
有幾臺電機三角形運行電機不轉，啟動(dòng)切換都正常（啟動(dòng)都是正轉）

在電機端調相讓電機反轉，啟動(dòng)運行都正常，然后去電源端調相讓電機正轉，啟動(dòng)運行也都正常。


有些電機在電機端調相一切正常，有些電機必須在電源端調相才能正常。


問(wèn)題來(lái)了，同樣是改變相序調相，為什么有幾個(gè)電機必須要在電源端調相才能正反轉啟動(dòng)運行都正常。
大家好~~請多多關(guān)照！ （滕州）配電柜，控制柜    各種設備電氣故障維修，電路故障處理  qq:7347737
