直流電機(jī)結(jié)構(gòu)原理簡(jiǎn)述
直流電機(jī)主要分為定子和轉(zhuǎn)子兩大部分。定轉(zhuǎn)子之間存在的間隙稱為氣隙。
1.定子
定子是電機(jī)的靜止部分,主要用來(lái)產(chǎn)生磁場(chǎng)。它主要包括:
(1)主磁極 主磁極包括鐵心和勵(lì)磁繞組兩部分。當(dāng)勵(lì)磁繞組中通人直流電流后,鐵心中即產(chǎn)生勵(lì)磁磁通,并在氣隙中建立勵(lì)磁磁場(chǎng)。勵(lì)磁繞組通常用圓形或矩形的絕緣導(dǎo)線制成一個(gè)集中的線圈,套在磁極鐵心外面。主磁極鐵心一般用1~1.5mm厚的低碳鋼板沖片疊壓鉚接而成,主磁極鐵心柱體部分稱為極身,靠近氣隙一端較寬的部分稱為極靴,極靴與極身交接處形成一個(gè)突出的肩部,用以支撐住勵(lì)磁繞組。極靴沿氣隙表面成弧形,使磁極下氣隙磁通密度分布更合理。整個(gè)主磁極用螺桿固定在機(jī)座上。
