1、電(dian)動(dong)機—般安裝在室內清潔(jie)、干燥的(de)場所，周圍必須通(tong)風良好，環境空氣(qi)最高溫(wen)度不(bu)超(chao)過40℃，最低(di)溫(wen)度不(bu)低(di)于-15℃，并應防止(zhi)強(qiang)烈(lie)的(de)熱輻射。  
2、按接(jie)(jie)線(xian)(xian)圖接(jie)(jie)電源線(xian)(xian)接(jie)(jie)線(xian)(xian)頭(tou)連接(jie)(jie)要緊固，帶引出電纜(lan)、電線(xian)(xian)的電動機，可直接(jie)(jie)和電源線(xian)(xian)連接(jie)(jie)，接(jie)(jie)頭(tou)處要絕緣密封。 
3、當電(dian)源(yuan)(yuan)線(xian)(xian)，相序(xu)和電(dian)動(dong)粗接(jie)線(xian)(xian)頭(tou)標志對應連接(jie)時(shi)，從軸伸端看電(dian)動(dong)機順時(shi)針旋轉。需要改變轉向時(shi)，改變兩根(gen)電(dian)源(yuan)(yuan)線(xian)(xian)接(jie)線(xian)(xian)的位置即可。 
4、YD系(xi)列等變(bian)級多(duo)速(su)異步電(dian)動機(ji)是(shi)利用(yong)換接(jie)引出線的方法來(lai)控(kong)制(zhi)(zhi)轉(zhuan)速(su)變(bian)化的，為保證多(duo)速(su)電(dian)動機(ji)運行的可靠性，設計和操作(zuo)控(kong)制(zhi)(zhi)裝置時(shi)應注意(yi)，在高速(su)切(qie)換為低(di)(di)(di)速(su)時(shi)，必須(xu)在切(qie)斷電(dian)源(yuan)的同時(shi)斷開2Y接(jie)線的中(zhong)(zhong)性點，以免在低(di)(di)(di)速(su)繞(rao)(rao)組接(jie)通時(shi)引起電(dian)源(yuan)短路(lu)．在高速(su)切(qie)換為低(di)(di)(di)速(su)的過程中(zhong)(zhong)，必續待電(dian)動機(ji)停轉(zhuan)后才能(neng)接(jie)通低(di)(di)(di)速(su)繞(rao)(rao)組的電(dian)源(yuan)，以減少(shao)對電(dian)動機(ji)及負載的沖擊．轉(zhuan)速(su)切(qie)換要注意(yi)電(dian)動機(ji)的轉(zhuan)向。 
5、電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)(dong)機可以(yi)采有聯(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)器，齒輪、皮(pi)帶與(yu)負載(zai)機械(xie)聯(lian)(lian)接，4kw以(yi)上(shang)的2極電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)(dong)機30kw以(yi)上(shang)的4極電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)(dong)機不宜用皮(pi)帶傳(chuan)動(dong)(dong)(dong)(dong)(dong)，雙軸(zhou)(zhou)(zhou)(zhou)伸電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)(dong)的第二(er)軸(zhou)(zhou)(zhou)(zhou)伸只(zhi)能用聯(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)囂傳(chuan)動(dong)(dong)(dong)(dong)(dong)。聯(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)器、皮(pi)帶輪軸(zhou)(zhou)(zhou)(zhou)孔與(yu)電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)(dong)機軸(zhou)(zhou)(zhou)(zhou)的配合(he)松(song)緊應(ying)合(he)適，安裝時嚴(yan)禁用重(zhong)錘敲擊。采用聯(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)器傳(chuan)動(dong)(dong)(dong)(dong)(dong)時，電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)(dong)機軸(zhou)(zhou)(zhou)(zhou)中心(xin)線與(yu)負載(zai)機械(xie)軸(zhou)(zhou)(zhou)(zhou)中心(xin)線應(ying)重(zhong)合(he)， 
聯軸(zhou)(zhou)器軸(zhou)(zhou)向(xiang)保留1～3mm間隙(xi)。 采(cai)用皮(pi)帶傳達室動(dong)時，電(dian)動(dong)機軸(zhou)(zhou)中(zhong)心線應與負(fu)載(zai)機械軸(zhou)(zhou)中(zhong)心線平行(xing)，皮(pi)帶中(zhong)心線與軸(zhou)(zhou)中(zhong)心線相互(hu)垂直。
