（1）拆裝前后要測(cè)試電動(dòng)機(jī)繞組絕緣及繞組直流電阻。

  （2）拆裝時(shí)不能用錘子直接敲擊零部件，應(yīng)墊銅捧或硬木對(duì)稱敲擊。

  （3）抽出和安裝轉(zhuǎn)子時(shí)，一定要按照要求逐步進(jìn)行．不得損傷定子繞組。

  （4）裝端蓋前應(yīng)用粗銅絲從軸承裝配孔伸入，鉤住內(nèi)軸承蓋．以便裝配外軸承蓋。

  （5）用熱套法安裝軸承時(shí)，加熱溫度應(yīng)在10O℃以下，聯(lián)軸器和帶輪的加熱溫度可稍微高一些，盡量減少敲擊．絕不可重?fù)簟?

  （6）電動(dòng)機(jī)加潤(rùn)滑脂時(shí)，其型號(hào)要符合電動(dòng)機(jī)的潤(rùn)滑要求．脂質(zhì)一定要干凈，加脂量不要過(guò)多，一般不超過(guò)軸承油室的2/3。加脂后，一定要隨手蓋好潤(rùn)滑脂桶，以防止雜質(zhì)、灰塵落入桶內(nèi)。

  （7）加潤(rùn)滑脂的工具應(yīng)選用干凈的專用工具．以避免污染潤(rùn)滑脂。

  （8）每臺(tái)電動(dòng)機(jī)拆裝、加潤(rùn)滑脂或更換軸承要有維修檔案。內(nèi)容包括：維修時(shí)間、內(nèi)容、軸承型號(hào)、潤(rùn)滑脂型號(hào)、工作負(fù)責(zé)人等，每項(xiàng)工序都要詳細(xì)記錄。另外，還要記錄軸承加熱的溫度、在100℃以下保持的時(shí)間及套裝軸承時(shí)的松緊度，掌握維修同類電動(dòng)機(jī)時(shí)對(duì)軸承加熱溫度的控制，以便于在滿足熱套裝的前提下．盡量降低軸承的加熱溫度。
