本人今天遇到了一件很頭痛的事情,我在一臺機器上用了一臺施耐德變頻器托動(dòng)兩個(gè)馬達,已經(jīng)用了好多年了,但今天卻出現了過(guò)流報警,單個(gè)馬達接上開(kāi)啟很正常,電流也很小,就是并在一起開(kāi)就不行了,請各位高手指點(diǎn)一下,這該如何去處理.

你驅動(dòng)的是三相電馬達嗎？
如果是，我也經(jīng)常這樣用一個(gè)變頻器驅動(dòng)兩個(gè)馬達，
你先確定馬達沒(méi)有問(wèn)題，因為這種方式是沒(méi)有問(wèn)題的
如果確實(shí)不行在每個(gè)馬達前各加熱繼電器，然后再接到控制回路里
這樣可以說(shuō)是雙保險
