3000/極對數
2極的就是3000轉左右。
4極的就是1500轉左右。。。。。。

各位大哥:
要看公式:三相異步電動(dòng)機轉速   n=60f/p*(1-s)
                                                        n:  三相異步電動(dòng)機轉速
                                                        f:  工作頻率
                                                        p: 磁極對數(既p/2)
                                                        s: 轉差率
      

     絕對正確.相信我沒(méi)錯.
        樓上的是同步電機的轉速.少了轉差率,所以2極三相電動(dòng)機的轉速大概在2800左右,
