style="text-indent:25px">三相異步電動機不用接零線，因為在任意時刻三相電的向量之和為零。即使接了零線也沒有電流存在，所以三相電機沒有零線，也就不需要接零線。三相電動機之所以沒有零線是因為零線與相線間的電壓是220V，而三相異步電動機所需電壓是380V，所以三相電動機要接三相電源線，而沒有零線。外殼接地的作用是防止某些相絕緣破損使外殼帶電使人發(fā)生觸電事故。但是變頻器的接地線較好不要和電機地線用同一個，因為在有些潮氣比較重的工廠環(huán)境接地線有可能時間長老化斷裂。三相異步電動機的接線方法有三角形接法和星形接法?！鞅硎救切谓臃?，就是把接線盒里上下相對的接線柱短接，得到三對電極，再分別接三相火線。Y表示星形接法，就是把接線盒里上面三個接線柱短接，下面三個接線柱分別接火線。邦飛利伺服控制器價錢一般的無刷直流電機本質(zhì)上屬于伺服電機由同步電機和驅(qū)動器構(gòu)成，是變頻調(diào)速電機。</p><div

style="text-indent:25px">機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。機座通常為鑄鐵件，大型異步電動機機座一般用鋼板焊成，微型電動機的機座采用鑄鋁件。封閉式電機的機座外面有散熱筋以增加散熱面積，防護(hù)式電機的機座兩端端蓋開有通風(fēng)孔，使電動機內(nèi)外的空氣可直接對流，以利于散熱。三相異步電動機的轉(zhuǎn)子鐵心是作為電機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的轉(zhuǎn)子鐵心直接壓裝在轉(zhuǎn)軸上，大、中型異步電動機（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。電動機的調(diào)速與控制是工農(nóng)業(yè)各類機械及辦公、民生電器設(shè)備的基礎(chǔ)技術(shù)之一。</p><div
