style="text-indent:25px">電磁式直流電動機由定子磁極、轉子（電樞）、換向器（俗稱整流子）、電刷、機殼、軸承等構成。lenze直角減速箱價錢</p><p style="text-indent:25px">直流電動機采用八角形全疊片結構，不僅空間利用率高，而且當采用靜止整流器供電時，能承受脈動電流和快速的負載電流變化。直流電動機一般不帶串勵繞組，適用于需要正、反電動機轉的自動控制技術中。根據(jù)用戶需要也可以制成帶串勵繞組。中心高100～280mm的電動機無補償繞組，但中心高250mm、280mm的電動機根據(jù)具體情況和需要可以制成帶補償繞組，中心高315～450mm的電動機帶有補償繞組。中心高500～710mm的電動機外形安裝尺寸及技術要求均符合IEC國際標準，電機的機械尺寸公差符合ISO國際標準。檢查電機接地裝置是否可靠。lenze直角減速箱價錢</p><p
