隔爆式三相異步電動機廠家

1. 全面符合國家標準（GB/T13957-92）
2. 電機效率比老產品平均提高2%
3. 采用箱形結構，實現零米布置，便于運輸、安裝、維修、保養。節省用戶的土建投資費，還可根據用戶需要靈活改變電機的通風防護型式。
4. 定子繞組采用“F”級無溶劑整浸絕緣系統
5. 電機采用端蓋式滑動軸承，為防止漏油采用“氣封”及浮動迷宮裝置結構
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。

作電動(dong)(dong)(dong)(dong)機運(yun)行的(de)三相異步電機。三相異步電動(dong)(dong)(dong)(dong)機轉(zhuan)(zhuan)子(zi)的(de)轉(zhuan)(zhuan)速低于旋轉(zhuan)(zhuan)磁(ci)場的(de)轉(zhuan)(zhuan)速，轉(zhuan)(zhuan)子(zi)繞(rao)組因(yin)與磁(ci)場間存(cun)在(zai)著(zhu)相對運(yun)動(dong)(dong)(dong)(dong)而產生電動(dong)(dong)(dong)(dong)勢和電流，并與磁(ci)場相互作用產生電磁(ci)轉(zhuan)(zhuan)矩，實現能量變(bian)換(huan)。

與(yu)單相異(yi)(yi)步電(dian)動(dong)(dong)機(ji)相比，三(san)相異(yi)(yi)步電(dian)動(dong)(dong)機(ji)運行性能好，并(bing)可(ke)節省各種材(cai)料。按轉子(zi)結(jie)構的(de)不同，三(san)相異(yi)(yi)步電(dian)動(dong)(dong)機(ji)可(ke)分為籠式(shi)和(he)(he)(he)繞線(xian)式(shi)兩種。籠式(shi)轉子(zi)的(de)異(yi)(yi)步電(dian)動(dong)(dong)機(ji)結(jie)構簡(jian)單、運行可(ke)靠、重(zhong)量輕、價格便宜，得到了(le)廣泛(fan)的(de)應用，其(qi)主要缺點是調(diao)速困(kun)難。繞線(xian)式(shi)三(san)相異(yi)(yi)步電(dian)動(dong)(dong)機(ji)的(de)轉子(zi)和(he)(he)(he)定子(zi)一樣(yang)也設(she)置了(le)三(san)相繞組并(bing)通過滑(hua)環、電(dian)刷與(yu)外(wai)部變(bian)阻(zu)器連接(jie)。調(diao)節變(bian)阻(zu)器電(dian)阻(zu)可(ke)以(yi)改善電(dian)動(dong)(dong)機(ji)的(de)起動(dong)(dong)性能和(he)(he)(he)調(diao)節電(dian)動(dong)(dong)機(ji)的(de)轉速。
