除此之外，也有電機(jī)安裝方面的原因。由于電機(jī)與負(fù)載機(jī)械之間的連接安裝不良，也必然造成電機(jī)運(yùn)行時(shí)的干擾力，使機(jī)組產(chǎn)生與轉(zhuǎn)速相同角頻率的振動。采用聯(lián)軸器、聯(lián)軸節(jié)連接時(shí)，應(yīng)保證同軸度要求；采用三角帶傳動連接時(shí)，應(yīng)保證帶槽的平行要求，減少皮帶的振動；采用齒輪傳動連接時(shí)，應(yīng)保證兩軸之間的平行度要求，使齒輪能正確嚙合。
電動機(jī)振動較平時(shí)大時(shí)，應(yīng)采用振動表沿水平和垂直方向測量各部分振動值，并做相應(yīng)記錄。傾聽電動機(jī)定子腔內(nèi)部聲音和軸承轉(zhuǎn)動聲音，檢查地腳，如無明顯異常現(xiàn)象，則采用脫開所拖動機(jī)械，單獨(dú)空轉(zhuǎn)電動機(jī)，以判定是電動機(jī)本身振動還是拖動機(jī)械引起的振動。在生產(chǎn)中會發(fā)現(xiàn)電動機(jī)修理后因種種原因致三相繞組磁勢不對稱，電動機(jī)在空載或低負(fù)荷時(shí)，表現(xiàn)出來的振動并不十分明顯，而一旦接帶的負(fù)荷加重，電動機(jī)振動也就逐漸加劇。
在生產(chǎn)中我們經(jīng)常采用斷電法來檢查區(qū)分是由于電磁還是機(jī)械原因引起的振動。斷電法即對運(yùn)行在額定轉(zhuǎn)速下的電動機(jī)采取忽然斷電，若振動忽然減小，則可判定是由電磁原因引起的，若振動值變化不是很大，則可能是機(jī)械方面的原因引起的。
