開放(fang)式防滴漏（ODP）

??開放式電(dian)(dian)機(ji)(ji)外殼(ke)(ke)(ke)允許冷空(kong)氣流(liu)過(guo)電(dian)(dian)機(ji)(ji)。轉子(zi)(zi)帶有(you)(you)風(feng)扇葉片，電(dian)(dian)機(ji)(ji)外殼(ke)(ke)(ke)型材(cai)，有(you)(you)助于空(kong)氣通過(guo)電(dian)(dian)機(ji)(ji)。開放式外殼(ke)(ke)(ke)的(de)一種(zhong)類型是ODP外殼(ke)(ke)(ke)。在ODP外殼(ke)(ke)(ke)中(zhong)，通風(feng)口防止液體和(he)固體從(cong)(cong)上方以(yi)高達(da)15°的(de)角度，從(cong)(cong)垂(chui)直方向進入電(dian)(dian)機(ji)(ji)內部并損壞操作組件。當(dang)(dang)(dang)電(dian)(dian)動機(ji)(ji)不處于水平位置時，例如當(dang)(dang)(dang)電(dian)(dian)動機(ji)(ji)安(an)裝在墻(qiang)壁(bi)上時，可能需要(yao)特殊的(de)蓋(gai)子(zi)(zi)來保護它。當(dang)(dang)(dang)環境沒有(you)(you)污染物且不考慮風(feng)雨的(de)情(qing)況下，可以(yi)ODP外殼(ke)(ke)(ke)。

??全封(feng)閉的非通風(feng)（TENV）

??有(you)時，電(dian)機周(zhou)圍(wei)的空氣中含有(you)腐蝕性(xing)元素、灰塵、沙子和(he)其他可(ke)能損壞電(dian)機內部(bu)部(bu)件的碎屑，或(huo)者(zhe)電(dian)機暴露在(zai)風(feng)力驅動的雨水(shui)或(huo)海水(shui)噴霧中。完全封(feng)閉(bi)的電(dian)機外(wai)殼不是氣密(mi)的，但它限制(zhi)了電(dian)機內部(bu)和(he)外(wai)部(bu)之間的自由空氣交(jiao)換。軸穿(chuan)過(guo)殼體的密(mi)封(feng)件可(ke)防止(zhi)水(shui)、灰塵和(he)其他可(ke)能沿軸進入電(dian)動機的異物。沒有(you)通風(feng)口(kou)意味著所有(you)熱(re)量都通過(guo)傳導通過(guo)外(wai)殼散發。

可能需(xu)要(yao)馬達外殼(ke)加(jia)工(gong)工(gong)人(ren)對(dui)機器(qi)進行(xing)成型和(he)成形編(bian)程，并操作該機器(qi)以制造成形的面(mian)板(ban)和(he)組件。電機外殼(ke)工(gong)人(ren)需(xu)要(yao)精(jing)通一系(xi)列(lie)(lie)連接(jie)(jie)和(he)緊固工(gong)藝，包括金屬活性氣體(ti)，鎢惰(duo)性氣體(ti)和(he)電阻點焊工(gong)藝。組件可以使用熱加(jia)工(gong)工(gong)藝或(huo)冷(leng)固定，如鉚接(jie)(jie)，擰(ning)緊和(he)粘接(jie)(jie)進行(xing)布(bu)置。機殼(ke)加(jia)工(gong)工(gong)人(ren)將使用一系(xi)列(lie)(lie)手工(gong)工(gong)具(ju)和(he)手工(gong)工(gong)具(ju)手動(dong)組裝(zhuang)(zhuang)，修整和(he)裝(zhuang)(zhuang)飾(shi)機殼(ke)面(mian)板(ban)和(he)組件。

一個(ge)馬達外(wai)殼加(jia)工(gong)工(gong)人(ren)將能夠(gou)操作所有(you)類型(xing)的焊接設備，手動(dong)和數控成形設備，機(ji)殼手工(gong)制(zhi)作和修整(zheng)工(gong)具以及一系(xi)列電動(dong)工(gong)具。機(ji)殼加(jia)工(gong)工(gong)人(ren)將使用計(ji)算機(ji)來開(kai)發(fa)機(ji)器使用的圖案，并在繪圖板上手動(dong)開(kai)發(fa)簡單圖案。

當電(dian)(dian)(dian)動(dong)機(ji)(ji)(ji)電(dian)(dian)(dian)機(ji)(ji)(ji)定子繞阻(zu)的絕(jue)緣層欠佳、絕(jue)緣層老化或電(dian)(dian)(dian)機(ji)(ji)(ji)風罩型號定子繞阻(zu)與電(dian)(dian)(dian)機(ji)(ji)(ji)外(wai)殼(ke)(ke)(ke)碰(peng)撞時，外(wai)殼(ke)(ke)(ke)感應起電(dian)(dian)(dian)，電(dian)(dian)(dian)動(dong)機(ji)(ji)(ji)外(wai)殼(ke)(ke)(ke)對(dui)地有(you)很高(gao)的工作電(dian)(dian)(dian)壓。假如電(dian)(dian)(dian)動(dong)機(ji)(ji)(ji)沒有(you)電(dian)(dian)(dian)線(xian)接頭，電(dian)(dian)(dian)機(ji)(ji)(ji)外(wai)殼(ke)(ke)(ke)顏色，人遇到電(dian)(dian)(dian)動(dong)機(ji)(ji)(ji)外(wai)殼(ke)(ke)(ke)時，蘭(lan)溪電(dian)(dian)(dian)機(ji)(ji)(ji)外(wai)殼(ke)(ke)(ke)，強勁的電(dian)(dian)(dian)流(liu)量經身體注入(ru)地面，便會導致(zhi)人身安全(quan)安全(quan)事故(gu)。

假如電(dian)(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)外(wai)殼(ke)(ke)(ke)接(jie)有接(jie)地(di)線，因為(wei)(wei)接(jie)地(di)線的(de)(de)電(dian)(dian)(dian)(dian)阻器(qi)不大(da)，電(dian)(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)外(wai)殼(ke)(ke)(ke)的(de)(de)電(dian)(dian)(dian)(dian)位差與(yu)地(di)面相同(tong)，電(dian)(dian)(dian)(dian)機(ji)(ji)塑料風罩人觸碰電(dian)(dian)(dian)(dian)機(ji)(ji)外(wai)殼(ke)(ke)(ke)就(jiu)不容易觸電(dian)(dian)(dian)(dian)事(shi)故。事(shi)實上(shang)當電(dian)(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)走(zou)電(dian)(dian)(dian)(dian)比較嚴重(zhong)，如電(dian)(dian)(dian)(dian)機(ji)(ji)定子繞阻與(yu)外(wai)殼(ke)(ke)(ke)碰撞時，因為(wei)(wei)根據接(jie)地(di)線接(jie)地(di)裝置，導致很高的(de)(de)短路容量，電(dian)(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)的(de)(de)繼電(dian)(dian)(dian)(dian)保(bao)護裝置設備姿勢，或保(bao)險管融(rong)斷，電(dian)(dian)(dian)(dian)機(ji)(ji)外(wai)殼(ke)(ke)(ke)標準，斷開開關電(dian)(dian)(dian)(dian)源，使電(dian)(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)慢下來。別(bie)的(de)(de)電(dian)(dian)(dian)(dian)氣設備外(wai)殼(ke)(ke)(ke)也必須電(dian)(dian)(dian)(dian)線接(jie)頭，其大(da)道理全是(shi)一(yi)樣(yang)的(de)(de)。因此以便確(que)保(bao)人身安全，電(dian)(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)沒有電(dian)(dian)(dian)(dian)線接(jie)頭是(shi)不允許(xu)運作的(de)(de)。
