1、電動機—般安裝在室內清潔(jie)、干燥的(de)場所，周圍(wei)必須(xu)通風良好(hao)，環(huan)境(jing)空氣(qi)最高溫(wen)度不(bu)超過(guo)40℃，最低(di)溫(wen)度不(bu)低(di)于-15℃，并應防止強(qiang)烈的(de)熱輻射。  
2、按接(jie)線(xian)圖接(jie)電(dian)(dian)源(yuan)線(xian)接(jie)線(xian)頭連接(jie)要緊固，帶(dai)引(yin)出電(dian)(dian)纜(lan)、電(dian)(dian)線(xian)的電(dian)(dian)動機，可直接(jie)和電(dian)(dian)源(yuan)線(xian)連接(jie)，接(jie)頭處要絕緣密(mi)封。 
3、當電(dian)源(yuan)(yuan)線(xian)(xian)，相序和(he)電(dian)動粗接(jie)線(xian)(xian)頭標志對應連接(jie)時，從軸伸端看電(dian)動機順時針旋轉(zhuan)。需要改變轉(zhuan)向時，改變兩根電(dian)源(yuan)(yuan)線(xian)(xian)接(jie)線(xian)(xian)的位置即可。 
4、YD系列等變級多速(su)(su)異步(bu)電(dian)(dian)動(dong)機是利用換接(jie)引出線的(de)(de)(de)方法來控制(zhi)轉(zhuan)速(su)(su)變化的(de)(de)(de)，為(wei)保證多速(su)(su)電(dian)(dian)動(dong)機運行的(de)(de)(de)可(ke)靠(kao)性(xing)，設計(ji)和操作控制(zhi)裝置時應注(zhu)意(yi)，在(zai)高速(su)(su)切換為(wei)低(di)(di)速(su)(su)時，必須在(zai)切斷電(dian)(dian)源(yuan)的(de)(de)(de)同時斷開2Y接(jie)線的(de)(de)(de)中性(xing)點，以免在(zai)低(di)(di)速(su)(su)繞組(zu)接(jie)通(tong)(tong)時引起電(dian)(dian)源(yuan)短路．在(zai)高速(su)(su)切換為(wei)低(di)(di)速(su)(su)的(de)(de)(de)過(guo)程(cheng)中，必續待電(dian)(dian)動(dong)機停轉(zhuan)后(hou)才(cai)能接(jie)通(tong)(tong)低(di)(di)速(su)(su)繞組(zu)的(de)(de)(de)電(dian)(dian)源(yuan)，以減少對電(dian)(dian)動(dong)機及負載的(de)(de)(de)沖擊(ji)．轉(zhuan)速(su)(su)切換要注(zhu)意(yi)電(dian)(dian)動(dong)機的(de)(de)(de)轉(zhuan)向。 
5、電(dian)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)(ji)(ji)(ji)可以采有聯(lian)軸(zhou)(zhou)器，齒(chi)輪、皮(pi)帶與負載機(ji)(ji)(ji)(ji)(ji)械(xie)聯(lian)接，4kw以上(shang)的2極(ji)電(dian)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)(ji)(ji)(ji)30kw以上(shang)的4極(ji)電(dian)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)(ji)(ji)(ji)不宜用皮(pi)帶傳動(dong)(dong)(dong)(dong)(dong)，雙軸(zhou)(zhou)伸(shen)電(dian)動(dong)(dong)(dong)(dong)(dong)的第二軸(zhou)(zhou)伸(shen)只能用聯(lian)軸(zhou)(zhou)囂傳動(dong)(dong)(dong)(dong)(dong)。聯(lian)軸(zhou)(zhou)器、皮(pi)帶輪軸(zhou)(zhou)孔與電(dian)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)(ji)(ji)(ji)軸(zhou)(zhou)的配合松(song)緊應合適，安裝時(shi)嚴禁用重錘敲擊。采用聯(lian)軸(zhou)(zhou)器傳動(dong)(dong)(dong)(dong)(dong)時(shi)，電(dian)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)(ji)(ji)(ji)軸(zhou)(zhou)中心(xin)線與負載機(ji)(ji)(ji)(ji)(ji)械(xie)軸(zhou)(zhou)中心(xin)線應重合， 
聯軸器軸向保留1～3mm間隙。 采用(yong)皮(pi)帶(dai)傳達室動時，電動機(ji)軸中心(xin)線(xian)(xian)應(ying)與(yu)負(fu)載(zai)機(ji)械軸中心(xin)線(xian)(xian)平行，皮(pi)帶(dai)中心(xin)線(xian)(xian)與(yu)軸中心(xin)線(xian)(xian)相互垂直。
