3、當電源線，相序和電動粗接(jie)線頭標志對(dui)應連接(jie)時(shi)，從軸伸端(duan)看(kan)電動機(ji)順時(shi)針旋轉。需要改變(bian)轉向(xiang)時(shi)，改變(bian)兩根電源線接(jie)線的位(wei)置即可。 
4、YD系列等變級多速(su)(su)異步電動(dong)(dong)(dong)機(ji)是(shi)利用換(huan)接(jie)引出線(xian)的方法來控(kong)制(zhi)轉(zhuan)(zhuan)速(su)(su)變化的，為保證多速(su)(su)電動(dong)(dong)(dong)機(ji)運行的可靠性，設計和操作控(kong)制(zhi)裝置時(shi)(shi)(shi)應注(zhu)意，在高速(su)(su)切換(huan)為低速(su)(su)時(shi)(shi)(shi)，必(bi)須(xu)在切斷電源的同時(shi)(shi)(shi)斷開(kai)2Y接(jie)線(xian)的中(zhong)性點，以(yi)免(mian)在低速(su)(su)繞組(zu)接(jie)通時(shi)(shi)(shi)引起(qi)電源短路．在高速(su)(su)切換(huan)為低速(su)(su)的過(guo)程中(zhong)，必(bi)續待電動(dong)(dong)(dong)機(ji)停轉(zhuan)(zhuan)后才能接(jie)通低速(su)(su)繞組(zu)的電源，以(yi)減少對電動(dong)(dong)(dong)機(ji)及(ji)負載的沖擊．轉(zhuan)(zhuan)速(su)(su)切換(huan)要注(zhu)意電動(dong)(dong)(dong)機(ji)的轉(zhuan)(zhuan)向。 
5、電(dian)(dian)動(dong)(dong)(dong)機可以(yi)采(cai)有聯(lian)軸(zhou)(zhou)器(qi)，齒輪、皮帶與負載機械(xie)聯(lian)接，4kw以(yi)上(shang)的(de)(de)2極(ji)電(dian)(dian)動(dong)(dong)(dong)機30kw以(yi)上(shang)的(de)(de)4極(ji)電(dian)(dian)動(dong)(dong)(dong)機不宜用皮帶傳(chuan)動(dong)(dong)(dong)，雙軸(zhou)(zhou)伸(shen)電(dian)(dian)動(dong)(dong)(dong)的(de)(de)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)、皮帶輪軸(zhou)(zhou)孔與電(dian)(dian)動(dong)(dong)(dong)機軸(zhou)(zhou)的(de)(de)配合(he)(he)松緊應合(he)(he)適(shi)，安裝時(shi)(shi)嚴禁用重錘敲擊。采(cai)用聯(lian)軸(zhou)(zhou)器(qi)傳(chuan)動(dong)(dong)(dong)時(shi)(shi)，電(dian)(dian)動(dong)(dong)(dong)機軸(zhou)(zhou)中心(xin)線與負載機械(xie)軸(zhou)(zhou)中心(xin)線應重合(he)(he)， 
聯(lian)軸(zhou)器(qi)軸(zhou)向(xiang)保留1～3mm間(jian)隙。 采用(yong)皮帶傳達室動(dong)時，電動(dong)機(ji)(ji)軸(zhou)中(zhong)心(xin)線(xian)(xian)應與負載機(ji)(ji)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。
