1、電動機—般安裝(zhuang)在(zai)室內清潔、干燥的場所(suo)，周圍必須通風(feng)良(liang)好，環境(jing)空氣(qi)最高溫度不超過40℃，最低(di)溫度不低(di)于-15℃，并應(ying)防(fang)止強烈的熱輻射。  
2、按接線圖接電(dian)源線接線頭連接要緊固，帶引出電(dian)纜、電(dian)線的(de)電(dian)動(dong)機，可直(zhi)接和電(dian)源線連接，接頭處要絕緣密封。 
3、當電(dian)源(yuan)線(xian)，相序和電(dian)動(dong)粗接(jie)線(xian)頭標(biao)志對應連(lian)接(jie)時(shi)，從軸(zhou)伸端看(kan)電(dian)動(dong)機順時(shi)針旋轉(zhuan)。需要(yao)改變轉(zhuan)向時(shi)，改變兩根電(dian)源(yuan)線(xian)接(jie)線(xian)的位(wei)置即可。 
4、YD系列等(deng)變(bian)級(ji)多速(su)(su)(su)(su)異步電(dian)(dian)(dian)(dian)動(dong)機(ji)是利用換(huan)接(jie)(jie)(jie)引出線的(de)方法來控制(zhi)轉(zhuan)(zhuan)速(su)(su)(su)(su)變(bian)化的(de)，為保證(zheng)多速(su)(su)(su)(su)電(dian)(dian)(dian)(dian)動(dong)機(ji)運行的(de)可靠性(xing)，設計和操(cao)作控制(zhi)裝(zhuang)置(zhi)時應注意，在(zai)高速(su)(su)(su)(su)切(qie)換(huan)為低速(su)(su)(su)(su)時，必須在(zai)切(qie)斷電(dian)(dian)(dian)(dian)源的(de)同(tong)時斷開2Y接(jie)(jie)(jie)線的(de)中性(xing)點，以(yi)免在(zai)低速(su)(su)(su)(su)繞組接(jie)(jie)(jie)通(tong)時引起電(dian)(dian)(dian)(dian)源短路(lu)．在(zai)高速(su)(su)(su)(su)切(qie)換(huan)為低速(su)(su)(su)(su)的(de)過程中，必續待電(dian)(dian)(dian)(dian)動(dong)機(ji)停轉(zhuan)(zhuan)后才能接(jie)(jie)(jie)通(tong)低速(su)(su)(su)(su)繞組的(de)電(dian)(dian)(dian)(dian)源，以(yi)減少(shao)對電(dian)(dian)(dian)(dian)動(dong)機(ji)及負載(zai)的(de)沖擊．轉(zhuan)(zhuan)速(su)(su)(su)(su)切(qie)換(huan)要注意電(dian)(dian)(dian)(dian)動(dong)機(ji)的(de)轉(zhuan)(zhuan)向(xiang)。 
5、電(dian)動(dong)(dong)機(ji)(ji)可以(yi)(yi)采有聯軸(zhou)(zhou)(zhou)器(qi)，齒(chi)輪(lun)、皮(pi)(pi)帶與負(fu)載(zai)機(ji)(ji)械(xie)聯接，4kw以(yi)(yi)上(shang)的2極電(dian)動(dong)(dong)機(ji)(ji)30kw以(yi)(yi)上(shang)的4極電(dian)動(dong)(dong)機(ji)(ji)不宜用(yong)皮(pi)(pi)帶傳動(dong)(dong)，雙軸(zhou)(zhou)(zhou)伸電(dian)動(dong)(dong)的第二軸(zhou)(zhou)(zhou)伸只能用(yong)聯軸(zhou)(zhou)(zhou)囂傳動(dong)(dong)。聯軸(zhou)(zhou)(zhou)器(qi)、皮(pi)(pi)帶輪(lun)軸(zhou)(zhou)(zhou)孔與電(dian)動(dong)(dong)機(ji)(ji)軸(zhou)(zhou)(zhou)的配合(he)(he)松緊應(ying)合(he)(he)適，安裝時嚴禁用(yong)重錘敲擊。采用(yong)聯軸(zhou)(zhou)(zhou)器(qi)傳動(dong)(dong)時，電(dian)動(dong)(dong)機(ji)(ji)軸(zhou)(zhou)(zhou)中(zhong)心線與負(fu)載(zai)機(ji)(ji)械(xie)軸(zhou)(zhou)(zhou)中(zhong)心線應(ying)重合(he)(he)， 
聯軸(zhou)(zhou)器軸(zhou)(zhou)向保留1～3mm間隙。 采用皮(pi)帶傳(chuan)達室動時，電動機軸(zhou)(zhou)中(zhong)心(xin)線(xian)應與負載機械軸(zhou)(zhou)中(zhong)心(xin)線(xian)平(ping)行，皮(pi)帶中(zhong)心(xin)線(xian)與軸(zhou)(zhou)中(zhong)心(xin)線(xian)相互垂直(zhi)。
