4HP 3KW 三(san)相(xiang)(xiang)(xiang)(xiang)異步(bu)(bu)電(dian)(dian)動(dong)(dong)(dong)機(ji)(ji) 是感應電(dian)(dian)動(dong)(dong)(dong)機(ji)(ji)的一(yi)(yi)種，是靠(kao)同(tong)(tong)(tong)時(shi)接(jie)入380V三(san)相(xiang)(xiang)(xiang)(xiang)交流(liu)電(dian)(dian)流(liu)（相(xiang)(xiang)(xiang)(xiang)位差120度）供電(dian)(dian)的一(yi)(yi)類電(dian)(dian)動(dong)(dong)(dong)機(ji)(ji)，由于三(san)相(xiang)(xiang)(xiang)(xiang)異步(bu)(bu)電(dian)(dian)動(dong)(dong)(dong)機(ji)(ji)的轉(zhuan)子與定子旋轉(zhuan)磁場以相(xiang)(xiang)(xiang)(xiang)同(tong)(tong)(tong)的方向、不(bu)同(tong)(tong)(tong)的轉(zhuan)速旋轉(zhuan)，存在(zai)轉(zhuan)差率，所以叫三(san)相(xiang)(xiang)(xiang)(xiang)異步(bu)(bu)電(dian)(dian)動(dong)(dong)(dong)機(ji)(ji)。

3HP 2.2KW 三(san)相(xiang)(xiang)異步電(dian)(dian)(dian)動(dong)機(ji) 當電(dian)(dian)(dian)動(dong)機(ji)的三(san)相(xiang)(xiang)定(ding)子(zi)繞(rao)(rao)組（各相(xiang)(xiang)差120度電(dian)(dian)(dian)角度），通入三(san)相(xiang)(xiang)對稱交流電(dian)(dian)(dian)后，將(jiang)產生一(yi)個(ge)旋轉(zhuan)(zhuan)磁(ci)(ci)(ci)場(chang)，該旋轉(zhuan)(zhuan)磁(ci)(ci)(ci)場(chang)切(qie)割轉(zhuan)(zhuan)子(zi)繞(rao)(rao)組，從而在(zai)(zai)轉(zhuan)(zhuan)子(zi)繞(rao)(rao)組中(zhong)產生感應電(dian)(dian)(dian)流（轉(zhuan)(zhuan)子(zi)繞(rao)(rao)組是閉(bi)合通路），載流的轉(zhuan)(zhuan)子(zi)導體在(zai)(zai)定(ding)子(zi)旋轉(zhuan)(zhuan)磁(ci)(ci)(ci)場(chang)作(zuo)用下將(jiang)產生電(dian)(dian)(dian)磁(ci)(ci)(ci)力，從而在(zai)(zai)電(dian)(dian)(dian)機(ji)轉(zhuan)(zhuan)軸上形成(cheng)電(dian)(dian)(dian)磁(ci)(ci)(ci)轉(zhuan)(zhuan)矩，驅動(dong)電(dian)(dian)(dian)動(dong)機(ji)旋轉(zhuan)(zhuan)，并且電(dian)(dian)(dian)機(ji)旋轉(zhuan)(zhuan)方向與旋轉(zhuan)(zhuan)磁(ci)(ci)(ci)場(chang)方向相(xiang)(xiang)同。

2HP 1.5KW 三相異(yi)步電(dian)(dian)(dian)動(dong)(dong)機 按轉子(zi)結構(gou)的不同(tong)，三相異(yi)步電(dian)(dian)(dian)動(dong)(dong)機可分為籠式(shi)和繞線式(shi)兩種。籠式(shi)轉子(zi)的異(yi)步電(dian)(dian)(dian)動(dong)(dong)機結構(gou)簡單、運行可靠、重量輕、價格便宜，得到了廣泛的應用，其主要(yao)缺點是調速(su)困難。繞線式(shi)三相異(yi)步電(dian)(dian)(dian)動(dong)(dong)機的轉子(zi)和定(ding)子(zi)一樣(yang)也設置了三相繞組并(bing)通過滑環、電(dian)(dian)(dian)刷與(yu)外(wai)部(bu)變阻(zu)器(qi)連接。調節變阻(zu)器(qi)電(dian)(dian)(dian)阻(zu)可以改善電(dian)(dian)(dian)動(dong)(dong)機的起動(dong)(dong)性(xing)能和調節電(dian)(dian)(dian)動(dong)(dong)機的轉速(su)。

1HP 0.75KW 三(san)相(xiang)(xiang)異步(bu)電(dian)動機(ji) 三(san)相(xiang)(xiang)異步(bu)電(dian)機(ji)是感應電(dian)動機(ji)的一種，是靠同(tong)時(shi)接入380V三(san)相(xiang)(xiang)交流電(dian)流（相(xiang)(xiang)位差120度）供(gong)電(dian)的一類(lei)電(dian)動機(ji)，由于(yu)三(san)相(xiang)(xiang)異步(bu)電(dian)動機(ji)的轉子(zi)與定子(zi)旋(xuan)轉磁場(chang)以相(xiang)(xiang)同(tong)的方向、不同(tong)的轉速旋(xuan)轉，存在(zai)轉差率，所以叫三(san)相(xiang)(xiang)異步(bu)電(dian)動機(ji)。
