1、電動機(ji)—般安裝在(zai)室內清潔、干燥(zao)的(de)場所，周圍必須通(tong)風(feng)良好，環境空氣最(zui)高溫(wen)度(du)不(bu)超過40℃，最(zui)低溫(wen)度(du)不(bu)低于-15℃，并(bing)應(ying)防止強烈的(de)熱輻射(she)。  
2、按接(jie)線(xian)(xian)圖(tu)接(jie)電源線(xian)(xian)接(jie)線(xian)(xian)頭連接(jie)要緊固，帶引出電纜(lan)、電線(xian)(xian)的電動機，可直接(jie)和電源線(xian)(xian)連接(jie)，接(jie)頭處要絕緣密封。 
3、當電(dian)(dian)(dian)源線(xian)，相序(xu)和電(dian)(dian)(dian)動粗接線(xian)頭標志對應(ying)連(lian)接時(shi)，從(cong)軸伸端(duan)看(kan)電(dian)(dian)(dian)動機(ji)順(shun)時(shi)針旋轉。需要改(gai)變(bian)轉向時(shi)，改(gai)變(bian)兩根(gen)電(dian)(dian)(dian)源線(xian)接線(xian)的(de)位置即(ji)可。 
4、YD系(xi)列(lie)等變級(ji)多(duo)速(su)(su)異步電(dian)(dian)動機(ji)(ji)是利用換(huan)接(jie)引出(chu)線的方(fang)法來控制轉速(su)(su)變化的，為保證(zheng)多(duo)速(su)(su)電(dian)(dian)動機(ji)(ji)運行(xing)的可靠性(xing)，設計和操作控制裝置時(shi)應注(zhu)意(yi)，在(zai)(zai)(zai)高(gao)速(su)(su)切換(huan)為低(di)速(su)(su)時(shi)，必須在(zai)(zai)(zai)切斷電(dian)(dian)源(yuan)的同時(shi)斷開2Y接(jie)線的中(zhong)性(xing)點，以免在(zai)(zai)(zai)低(di)速(su)(su)繞組接(jie)通(tong)時(shi)引起電(dian)(dian)源(yuan)短路(lu)．在(zai)(zai)(zai)高(gao)速(su)(su)切換(huan)為低(di)速(su)(su)的過程中(zhong)，必續待電(dian)(dian)動機(ji)(ji)停(ting)轉后(hou)才能接(jie)通(tong)低(di)速(su)(su)繞組的電(dian)(dian)源(yuan)，以減少對電(dian)(dian)動機(ji)(ji)及負載的沖擊．轉速(su)(su)切換(huan)要注(zhu)意(yi)電(dian)(dian)動機(ji)(ji)的轉向。 
5、電動(dong)機可以采有聯(lian)(lian)軸(zhou)器，齒輪(lun)、皮(pi)帶與負(fu)載(zai)機械聯(lian)(lian)接，4kw以上的(de)2極電動(dong)機30kw以上的(de)4極電動(dong)機不宜用(yong)(yong)皮(pi)帶傳(chuan)動(dong)，雙軸(zhou)伸(shen)電動(dong)的(de)第二軸(zhou)伸(shen)只(zhi)能(neng)用(yong)(yong)聯(lian)(lian)軸(zhou)囂傳(chuan)動(dong)。聯(lian)(lian)軸(zhou)器、皮(pi)帶輪(lun)軸(zhou)孔與電動(dong)機軸(zhou)的(de)配(pei)合松緊(jin)應(ying)合適，安裝時嚴(yan)禁用(yong)(yong)重錘敲擊。采用(yong)(yong)聯(lian)(lian)軸(zhou)器傳(chuan)動(dong)時，電動(dong)機軸(zhou)中(zhong)(zhong)心線(xian)與負(fu)載(zai)機械軸(zhou)中(zhong)(zhong)心線(xian)應(ying)重合， 
聯軸(zhou)器軸(zhou)向保留1～3mm間隙。 采用皮帶傳達室動(dong)時(shi)，電(dian)動(dong)機軸(zhou)中(zhong)心(xin)線(xian)(xian)應與負載機械軸(zhou)中(zhong)心(xin)線(xian)(xian)平行，皮帶中(zhong)心(xin)線(xian)(xian)與軸(zhou)中(zhong)心(xin)線(xian)(xian)相互(hu)垂直。
