1、電動機(ji)—般安裝在室內清(qing)潔、干燥的場(chang)所，周圍(wei)必須(xu)通風良(liang)好，環境(jing)空氣最高溫(wen)度(du)不(bu)超過40℃，最低溫(wen)度(du)不(bu)低于-15℃，并應防止強烈(lie)的熱輻射(she)。  
2、按接(jie)線(xian)圖接(jie)電(dian)(dian)源線(xian)接(jie)線(xian)頭(tou)連接(jie)要(yao)緊固(gu)，帶(dai)引出電(dian)(dian)纜、電(dian)(dian)線(xian)的電(dian)(dian)動機，可直接(jie)和電(dian)(dian)源線(xian)連接(jie)，接(jie)頭(tou)處(chu)要(yao)絕(jue)緣密(mi)封(feng)。 
3、當(dang)電(dian)源(yuan)線，相序和電(dian)動(dong)粗接線頭標志對應連(lian)接時(shi)(shi)，從軸伸端看電(dian)動(dong)機順時(shi)(shi)針旋(xuan)轉(zhuan)(zhuan)。需要改(gai)變轉(zhuan)(zhuan)向時(shi)(shi)，改(gai)變兩根電(dian)源(yuan)線接線的位置(zhi)即可(ke)。 
4、YD系列等(deng)變(bian)級(ji)多速(su)異步電(dian)(dian)(dian)動(dong)機(ji)是利用換(huan)(huan)接(jie)引(yin)出線的(de)(de)(de)方法來(lai)控制轉速(su)變(bian)化的(de)(de)(de)，為保證多速(su)電(dian)(dian)(dian)動(dong)機(ji)運行的(de)(de)(de)可靠(kao)性(xing)(xing)，設(she)計和操作控制裝置(zhi)時(shi)應注(zhu)(zhu)意(yi)(yi)，在(zai)(zai)高速(su)切(qie)(qie)換(huan)(huan)為低(di)(di)速(su)時(shi)，必(bi)須在(zai)(zai)切(qie)(qie)斷電(dian)(dian)(dian)源的(de)(de)(de)同時(shi)斷開2Y接(jie)線的(de)(de)(de)中性(xing)(xing)點，以(yi)免在(zai)(zai)低(di)(di)速(su)繞(rao)組(zu)接(jie)通(tong)時(shi)引(yin)起電(dian)(dian)(dian)源短路．在(zai)(zai)高速(su)切(qie)(qie)換(huan)(huan)為低(di)(di)速(su)的(de)(de)(de)過程中，必(bi)續待電(dian)(dian)(dian)動(dong)機(ji)停(ting)轉后才能接(jie)通(tong)低(di)(di)速(su)繞(rao)組(zu)的(de)(de)(de)電(dian)(dian)(dian)源，以(yi)減少對(dui)電(dian)(dian)(dian)動(dong)機(ji)及負載的(de)(de)(de)沖擊．轉速(su)切(qie)(qie)換(huan)(huan)要(yao)注(zhu)(zhu)意(yi)(yi)電(dian)(dian)(dian)動(dong)機(ji)的(de)(de)(de)轉向。 
5、電(dian)動(dong)機(ji)(ji)可(ke)以(yi)采(cai)有(you)聯軸(zhou)器，齒輪、皮(pi)帶與(yu)負載機(ji)(ji)械(xie)聯接，4kw以(yi)上的(de)(de)2極電(dian)動(dong)機(ji)(ji)30kw以(yi)上的(de)(de)4極電(dian)動(dong)機(ji)(ji)不宜用(yong)(yong)皮(pi)帶傳動(dong)，雙軸(zhou)伸電(dian)動(dong)的(de)(de)第二軸(zhou)伸只能用(yong)(yong)聯軸(zhou)囂傳動(dong)。聯軸(zhou)器、皮(pi)帶輪軸(zhou)孔與(yu)電(dian)動(dong)機(ji)(ji)軸(zhou)的(de)(de)配合(he)松緊應合(he)適(shi)，安裝時嚴(yan)禁用(yong)(yong)重錘敲擊。采(cai)用(yong)(yong)聯軸(zhou)器傳動(dong)時，電(dian)動(dong)機(ji)(ji)軸(zhou)中(zhong)心線與(yu)負載機(ji)(ji)械(xie)軸(zhou)中(zhong)心線應重合(he)， 
聯軸(zhou)器軸(zhou)向(xiang)保(bao)留1～3mm間隙。 采用皮帶傳達室動時，電動機軸(zhou)中(zhong)(zhong)心線(xian)應(ying)與負(fu)載機械(xie)軸(zhou)中(zhong)(zhong)心線(xian)平行，皮帶中(zhong)(zhong)心線(xian)與軸(zhou)中(zhong)(zhong)心線(xian)相互垂直。
