style="text-indent:25px">機(jī)座作用是固定定子鐵心與前后端蓋以支撐轉(zhuǎn)子，并起防護(hù)、散熱等作用。機(jī)座通常為鑄鐵件，大型異步電動機(jī)機(jī)座一般用鋼板焊成，微型電動機(jī)的機(jī)座采用鑄鋁件。封閉式電機(jī)的機(jī)座外面有散熱筋以增加散熱面積，防護(hù)式電機(jī)的機(jī)座兩端端蓋開有通風(fēng)孔，使電動機(jī)內(nèi)外的空氣可直接對流，以利于散熱。三相異步電動機(jī)的轉(zhuǎn)子鐵心是作為電機(jī)磁路的一部分以及在鐵心槽內(nèi)放置轉(zhuǎn)子繞組。所用材料與定子一樣，由0.5毫米厚的硅鋼片沖制、疊壓而成，硅鋼片外圓沖有均勻分布的孔，用來安置轉(zhuǎn)子繞組。通常用定子鐵心沖落后的硅鋼片內(nèi)圓來沖制轉(zhuǎn)子鐵心。一般小型異步電動機(jī)的轉(zhuǎn)子鐵心直接壓裝在轉(zhuǎn)軸上，大、中型異步電動機(jī)（轉(zhuǎn)子直徑在300~400毫米以上）的轉(zhuǎn)子鐵心則借助與轉(zhuǎn)子支架壓在轉(zhuǎn)軸上。</p><p
