1、電動(dong)機—般安裝(zhuang)在室(shi)內清潔、干(gan)燥(zao)的(de)場所，周圍(wei)必須(xu)通風良好，環境空氣最高(gao)溫(wen)度不(bu)超過40℃，最低溫(wen)度不(bu)低于-15℃，并(bing)應(ying)防(fang)止強烈(lie)的(de)熱輻(fu)射。  
2、按接(jie)(jie)線(xian)圖接(jie)(jie)電(dian)源線(xian)接(jie)(jie)線(xian)頭連(lian)接(jie)(jie)要緊(jin)固(gu)，帶(dai)引出電(dian)纜、電(dian)線(xian)的電(dian)動機，可直接(jie)(jie)和電(dian)源線(xian)連(lian)接(jie)(jie)，接(jie)(jie)頭處要絕緣密(mi)封。 
3、當電(dian)源線(xian)(xian)，相序和電(dian)動(dong)粗接線(xian)(xian)頭(tou)標志對應連接時，從(cong)軸伸端看(kan)電(dian)動(dong)機順時針旋轉。需要改變(bian)轉向時，改變(bian)兩(liang)根電(dian)源線(xian)(xian)接線(xian)(xian)的位置即可。 
4、YD系列(lie)等變級多速(su)異(yi)步電(dian)(dian)動機是利用換接(jie)(jie)(jie)引出線的(de)(de)方法來控制轉(zhuan)速(su)變化的(de)(de)，為保證多速(su)電(dian)(dian)動機運行的(de)(de)可靠性，設(she)計(ji)和操作控制裝置時(shi)(shi)應注(zhu)(zhu)意，在高速(su)切(qie)換為低速(su)時(shi)(shi)，必須在切(qie)斷(duan)(duan)電(dian)(dian)源的(de)(de)同時(shi)(shi)斷(duan)(duan)開2Y接(jie)(jie)(jie)線的(de)(de)中性點，以(yi)免在低速(su)繞(rao)組(zu)接(jie)(jie)(jie)通(tong)時(shi)(shi)引起電(dian)(dian)源短路(lu)．在高速(su)切(qie)換為低速(su)的(de)(de)過程(cheng)中，必續待電(dian)(dian)動機停轉(zhuan)后才能接(jie)(jie)(jie)通(tong)低速(su)繞(rao)組(zu)的(de)(de)電(dian)(dian)源，以(yi)減(jian)少對電(dian)(dian)動機及負載的(de)(de)沖擊．轉(zhuan)速(su)切(qie)換要注(zhu)(zhu)意電(dian)(dian)動機的(de)(de)轉(zhuan)向(xiang)。 
5、電(dian)(dian)動(dong)(dong)(dong)機(ji)(ji)(ji)(ji)(ji)可以采有聯(lian)軸(zhou)(zhou)器(qi)(qi)，齒輪、皮帶(dai)與負載機(ji)(ji)(ji)(ji)(ji)械(xie)聯(lian)接，4kw以上(shang)的2極(ji)電(dian)(dian)動(dong)(dong)(dong)機(ji)(ji)(ji)(ji)(ji)30kw以上(shang)的4極(ji)電(dian)(dian)動(dong)(dong)(dong)機(ji)(ji)(ji)(ji)(ji)不宜(yi)用皮帶(dai)傳(chuan)動(dong)(dong)(dong)，雙軸(zhou)(zhou)伸(shen)電(dian)(dian)動(dong)(dong)(dong)的第二軸(zhou)(zhou)伸(shen)只能用聯(lian)軸(zhou)(zhou)囂傳(chuan)動(dong)(dong)(dong)。聯(lian)軸(zhou)(zhou)器(qi)(qi)、皮帶(dai)輪軸(zhou)(zhou)孔與電(dian)(dian)動(dong)(dong)(dong)機(ji)(ji)(ji)(ji)(ji)軸(zhou)(zhou)的配合(he)松緊應合(he)適(shi)，安裝(zhuang)時(shi)嚴禁用重(zhong)錘敲擊。采用聯(lian)軸(zhou)(zhou)器(qi)(qi)傳(chuan)動(dong)(dong)(dong)時(shi)，電(dian)(dian)動(dong)(dong)(dong)機(ji)(ji)(ji)(ji)(ji)軸(zhou)(zhou)中(zhong)(zhong)心線與負載機(ji)(ji)(ji)(ji)(ji)械(xie)軸(zhou)(zhou)中(zhong)(zhong)心線應重(zhong)合(he)， 
聯(lian)軸(zhou)器軸(zhou)向保(bao)留1～3mm間隙。 采用皮帶傳達室動時，電動機軸(zhou)中(zhong)心線應與負載(zai)機械軸(zhou)中(zhong)心線平行，皮帶中(zhong)心線與軸(zhou)中(zhong)心線相互垂(chui)直。
