直流电机结构原理简述
直流电机主要分为定子和转子两大部分。定转子之间存在的间隙称为气隙。
1.定子
定子是电机的静止部分,主要用来产生磁场。它主要包括:
(1)主磁极 主磁极包括铁心和励磁绕组两部分。当励磁绕组中通人直流电流后,铁心中即产生励磁磁通,并在气隙中建立励磁磁场。励磁绕组通常用圆形或矩形的绝缘导线制成一个集中的线圈,套在磁极铁心外面。主磁极铁心一般用1~1.5mm厚的低碳钢板冲片叠压铆接而成,主磁极铁心柱体部分称为极身,靠近气隙一端较宽的部分称为极靴,极靴与极身交接处形成一个突出的肩部,用以支撑住励磁绕组。极靴沿气隙表面成弧形,使磁极下气隙磁通密度分布更合理。整个主磁极用螺杆固定在机座上。
