如(ru)果沒有固定膠的(de)話，原因(yin)如(ru)下：
(1)硅鋼片周邊(bian)毛刺大，疊(die)縫間隙(xi)不符合要求(qiu)。
(2)碟片有(you)差錯(cuo)，造成空片、搭頭，使鐵芯疊裝后壓不實。
(3)鐵芯(xin)片有波浪、彎曲(qu)，使疊壓后夾不緊。
(4)綁扎鐵軛和(he)鐵芯(xin)的環(huan)氧樹脂玻璃(li)絲帶材質(zhi)不(bu)佳、工藝不(bu)當(dang)、綁扎拉力(li)不(bu)夠及固(gu)(gu)化不(bu)成(cheng)(cheng)堅固(gu)(gu)整體等，均造成(cheng)(cheng)綁扎過松、綁箍老化以及出現故障，造成(cheng)(cheng)鐵芯(xin)松動。
(5)夾件緊(jin)固(gu)螺栓(shuan)未(wei)擰緊(jin)，或未(wei)裝防(fang)松(song)墊圈，運行經電磁力振動(dong)后變松(song)，使(shi)鐵(tie)芯變松(song)，同(tong)時引起(qi)接地銅片脫落。
(6)對于夾件(jian)緊固螺(luo)栓未擰緊或有輕微(wei)的振動噪(zao)聲，可再次用大扳手重新(xin)擰緊緊固螺(luo)栓，直至噪(zao)聲消(xiao)除即可;如(ru)果噪(zao)聲未消(xiao)除，需(xu)要進(jin)一步采取措施。
(7)對(dui)于有少量空片(pian)(pian)(pian)(pian)(pian)、搭頭、波(bo)浪(lang)、彎(wan)曲(qu)、損壞(huai)的硅(gui)(gui)鋼片(pian)(pian)(pian)(pian)(pian)發出(chu)噪聲(sheng)，可(ke)再(zai)(zai)次擰(ning)緊緊固螺栓(shuan)，或加墊紙(zhi)板再(zai)(zai)擰(ning)緊，如果聲(sheng)音消失(shi)便可(ke)，否則要拆開鐵芯(xin)重(zhong)(zhong)新(xin)挑(tiao)(tiao)選硅(gui)(gui)鋼片(pian)(pian)(pian)(pian)(pian)，再(zai)(zai)重(zhong)(zhong)新(xin)疊(die)鐵芯(xin)壓(ya)裝。在挑(tiao)(tiao)選硅(gui)(gui)鋼片(pian)(pian)(pian)(pian)(pian)時，應兩片(pian)(pian)(pian)(pian)(pian)一疊(die)的，誤插一片(pian)(pian)(pian)(pian)(pian)或三片(pian)(pian)(pian)(pian)(pian)一疊(die)的，應一律(lv)改為兩片(pian)(pian)(pian)(pian)(pian);要挑(tiao)(tiao)選厚度相同(tong)的疊(die)片(pian)(pian)(pian)(pian)(pian);將(jiang)彎(wan)曲(qu)片(pian)(pian)(pian)(pian)(pian)、殘片(pian)(pian)(pian)(pian)(pian)及波(bo)浪(lang)嚴重(zhong)(zhong)的硅(gui)(gui)鋼片(pian)(pian)(pian)(pian)(pian)挑(tiao)(tiao)出(chu)不用(yong);毛刺(ci)(ci)大的硅(gui)(gui)鋼片(pian)(pian)(pian)(pian)(pian)需(xu)要重(zhong)(zhong)新(xin)去毛刺(ci)(ci)，毛刺(ci)(ci)達到小于0.03毫米后(hou)再(zai)(zai)重(zhong)(zhong)新(xin)疊(die)裝。
(8)對于環氧(yang)樹脂玻璃絲帶綁箍(gu)(gu)(gu)損壞、老化、松動等故障，一律重新進行(xing)綁扎(zha)，要求材料合(he)格。綁扎(zha)時(shi)先用臨(lin)時(shi)鋼箍(gu)(gu)(gu)箍(gu)(gu)(gu)緊，然(ran)后(hou)綁扎(zha)達一定厚(hou)度后(hou)進行(xing)烘干固化，固化成(cheng)堅硬的(de)整(zheng)體后(hou)再卸去臨(lin)時(shi)鋼箍(gu)(gu)(gu)。
