電動機設備廠家的原理：

是把電(dian)(dian)(dian)(dian)能(neng)轉(zhuan)換成機(ji)(ji)(ji)(ji)械能(neng)的(de)一種設備。它(ta)是利用(yong)通電(dian)(dian)(dian)(dian)線(xian)(xian)圈（也就是定(ding)子(zi)(zi)(zi)繞組）產生旋(xuan)轉(zhuan)磁(ci)(ci)場(chang)并作用(yong)于轉(zhuan)子(zi)(zi)(zi)（如(ru)鼠籠式(shi)閉合鋁框）形(xing)成磁(ci)(ci)電(dian)(dian)(dian)(dian)動(dong)(dong)力旋(xuan)轉(zhuan)扭矩。電(dian)(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)(ji)(ji)按使用(yong)電(dian)(dian)(dian)(dian)源不同分為直流(liu)電(dian)(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)(ji)(ji)和交(jiao)(jiao)流(liu)電(dian)(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)(ji)(ji)，電(dian)(dian)(dian)(dian)力系(xi)統(tong)中的(de)電(dian)(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)(ji)(ji)大部分是交(jiao)(jiao)流(liu)電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)(ji)，可以是同步電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)(ji)或者是異步電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)(ji)（電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)(ji)定(ding)子(zi)(zi)(zi)磁(ci)(ci)場(chang)轉(zhuan)速與轉(zhuan)子(zi)(zi)(zi)旋(xuan)轉(zhuan)轉(zhuan)速不保持(chi)同步速）。電(dian)(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)(ji)(ji)主要由(you)定(ding)子(zi)(zi)(zi)與轉(zhuan)子(zi)(zi)(zi)組成，通電(dian)(dian)(dian)(dian)導線(xian)(xian)在磁(ci)(ci)場(chang)中受(shou)力運動(dong)(dong)的(de)方(fang)向跟(gen)電(dian)(dian)(dian)(dian)流(liu)方(fang)向和磁(ci)(ci)感線(xian)(xian)（磁(ci)(ci)場(chang)方(fang)向）方(fang)向有關。電(dian)(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)(ji)(ji)工(gong)作原理是磁(ci)(ci)場(chang)對(dui)電(dian)(dian)(dian)(dian)流(liu)受(shou)力的(de)作用(yong)，使電(dian)(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)(ji)(ji)轉(zhuan)動(dong)(dong)。

電動機設備廠家適用范圍：

允許全壓(ya)直接起(qi)(qi)動(dong)(dong)(dong)，如負載轉(zhuan)(zhuan)矩不(bu)大，也可采(cai)用降(jiang)壓(ya)起(qi)(qi)動(dong)(dong)(dong)方式(shi)，降(jiang)壓(ya)起(qi)(qi)動(dong)(dong)(dong)時電動(dong)(dong)(dong)機(ji)的起(qi)(qi)動(dong)(dong)(dong)轉(zhuan)(zhuan)矩大致與電壓(ya)平方成正(zheng)比的下降(jiang)，如果負載機(ji)械的轉(zhuan)(zhuan)動(dong)(dong)(dong)慣量（J）值在一定的范圍內，則電動(dong)(dong)(dong)機(ji)允許冷態連續起(qi)(qi)動(dong)(dong)(dong)兩次，熱太連續起(qi)(qi)動(dong)(dong)(dong)一次。

特點如下：

1. 全面符合國家標準（GB/T13957-92）

2. 電機效率比老(lao)產品(pin)平均提高2%

3. 采用(yong)箱形結構，實(shi)現零米布置，便于運輸、安(an)裝、維修、保(bao)養(yang)。節省(sheng)用(yong)戶的(de)土建投資費(fei)，還(huan)可根據用(yong)戶需要靈活改變(bian)電機的(de)通(tong)風防(fang)護(hu)型式。

4. 定子繞組(zu)采用(yong)“F”級無(wu)溶劑(ji)整浸絕緣系統

5. 電機采用端(duan)蓋式滑動(dong)軸承，為(wei)防(fang)止(zhi)漏油采用“氣(qi)封(feng)”及浮(fu)動(dong)迷(mi)宮裝置結構

6. 三相電機采用鑄鋁或銅排轉子，運行可靠。
通風、防護型式：電機通風采用徑向自通風方式，冷卻空氣從電機上罩軸向兩側進入，經電機內部然后由上罩沿徑向兩側排出。
