直流電機維修定子主要組成
  2019-07-16  

直流電機維修由直流電動機和發電機工作原理示意圖可以看到,直流電機的結構應由定子和轉子兩大部分組成。直流電機運行時靜止不動的部分稱為定子,定子的主要作用是產生磁場,由機座、主磁極、換向極、端蓋、軸承和電刷裝置等組成。運行時轉動的部分稱為轉子,其主要作用是產生電磁轉矩和感應電動勢,是直流電機進行能量轉換的樞紐,所以通常又稱為電樞,由轉軸、電樞鐵心、電樞繞組、換向器和風扇等組成。

直流電機維修

(3)直流電機維修端蓋、軸承蓋前后端蓋用來支撐整個轉子,它借助正口結構與機座固定,轉軸通過端蓋中心孔安裝的軸承而直接得到支撐,而軸承中心與端蓋止口外圓同心,這就使電樞的旋轉中心線與機座中心線重合以保證電樞與磁極間的間隙均勻。同時端蓋也是電機的防護蓋。
