水泵電機解決方案

　　鼠籠電(dian)(dian)(dian)機(ji)(ji)(ji)(ji)適用(yong)于輕(qing)負載的(de)通(tong)用(yong)類機(ji)(ji)(ji)(ji)械(xie)設備(bei)，使(shi)(shi)用(yong)的(de)場合(he)很多，幾乎使(sh贞绳i)(shi)用(yong)在日常生活、工廠設備(bei)，比如風機(ji)(ji)(ji)(ji)，水泵，壓縮(suo)機(ji)(ji)(ji)(ji)，礦山機(ji)(ji)(ji)(ji)械(xie)等各各領域，也就是(shi)我(wo)們通(tong)常所(suo)說的(de)風機(ji)(ji)(ji)(ji)電(dian)(dian)(dian)機(ji)(ji)(ji)(ji)水泵電(dian)(dian)(dian)機(ji)(ji)(ji)(ji)壓縮(suo)機(ji)(ji)(ji)(ji)電(dian)(dian)(dian)機(ji)(ji)(ji)(ji)礦用(yong)電(dian)(dian)(dian)機(ji)(ji)(ji)(ji)，這(zhe)種電(dian)(dian)(dian)動(dong)機(ji)(ji)(ji)(ji)的(de)優點是(shi)結構簡單，轉子上無繞組，啟動(dong)扭矩(ju)相對(dui)較小，維修威沙成本(ben)低，而使(shi)(shi)用(yong)壽命長。

　　工作原理

　　電動(dong)(dong)機(ji)的(de)定(ding)子(zi)(zi)上為(wei)(wei)三相(xiang)散嵌式分布繞(rao)組(zu)，轉(zhuan)子(zi)(zi)為(wei)(wei)籠式的(de)導(dao)條(tiao)(tiao)(因該導(dao)條(tiao)(tiao)形狀與鼠(shu)(shu)籠相(罗迎xiang)似，所以(yi)又稱鼠(shu)(shu)籠式異步電動(dong)(dong)機(ji))。電動(dong)(dong)機(ji)在定(ding)子(zi)(zi)繞(rao)組(zu)加三相(xiang)交流電后，會形成旋轉(zhuan)磁場(chang)，其(qi)轉(zhuan)子(zi)(zi)上的(de)閉合的(de)導(dao)條(tiao)(tiao)會因為(wei)(wei)切割定(ding)子(zi)(zi)磁場(chang)的(de)磁力(li)線(xian)而感應出(chu)電勢和電流，而帶電(電流)的(de)導(dao)體在磁場(chang)中就會產生運動(dong)(dong)，這樣電動(dong)(dong)機(ji)轉(圃郊zhuan)子(zi)(zi)就旋轉(zhuan)起來(lai)了(le)。

　　起動方式

　　水泵異步電動機起(qi)動方式包括(kuo)直接起(qi)動，降壓起(qi)動。降壓起(qi)動包括(kuo)自(zi)骂簿藕(ou)補償起(qi)動，星角換接起(qi)動，延邊三角形起(qi)動。

　　一(yi)般中小(xiao)(xiao)型鼠籠(long)式(shi)異步電(dian)(dian)動(dong)(dong)機可(ke)以直(zhi)接(jie)啟動(dong)(dong)，直匆赃(zhi)接(jie)起(qi)動(dong)(dong)設備簡(jian)單，方(fang)法簡(jian)便。但起(qi)動(dong)(dong)電(dian)(dian)流(liu)大，起(qi)動(dong)(dong)轉矩小(xiao)(xiao)。大容量的(de)鼠籠(long)式(shi)異步電(dian)(dian)動(dong)(dong)機一(yi)般采用降低定子(zi)繞組端電(dian)(dian)壓的(de)方(fang)法起(qi)動(dong)(dong)，降壓起(qi)動(dong)(dong)時(shi)，可(ke)以減(jian)小(xiao)(xiao)起(qi)動(dong)(dong)電(dian)(dian)流(liu)，但也不可(ke)避(bi)免地減(jian)小(xiao)(xiao)了起(qi)動(dong)(dong)轉矩。
