對380V、3相籠(long)形電(dian)動機(ji)他(ta)是(shi)個老(lao)問題(ti)，或許幾20年(nian)之前(qian)都(dou)有(you)4.結(jie)果(guo)，但基本上(shang)(shang)是(shi)新問題(ti)，接下(xia)來(lai)的多半數4.結(jie)果(guo)都(dou)敵不過來(lai)問個為任何？和實際(ji)上(shang)(shang)的里面(mian)都(dou)沒(mei)有(you)可實際(ji)使用。

1、電(dian)動四(si)輪機額定功率以上10kW。

2、電動(dong)伸(shen)縮機電功率高于50kW。
