【正文】 Expand for guarding against a malfunction, Ensure that equipment is regular， Respond to the cause judging a malfunction in time, The small advantages being in progress is handled, This is working important one job. Therefore failure happened in routine attention to cutting down and avoiding an electric motor in operation be pretty important, The among them the most important link is to make a circuit of examine that and removes any freak initiation origin in time. Appear to carry out accident analysis , adopt a countermeasure carefully after the accident , be that cutting down accident number of times and the efficiency keeping electric motor operation in repair , improving is that the essential technology works then. The electric motor routine attention works regularly to the person no doubt very important, But, in actual operation, since every aspect cause is unable, rightness selects and uses an electric motor, The routine attention being in progress in time waits for various form easy to appear malfunction. The malfunction cause acmodating oneself to essential points for this purpose to the electric motor carries out multianalysis , finds out have problem. Motor rotors among them malfunction, Warm up an impact of litre over electric motor lifespan, Cities such as electric motor vibration , the electric motor noise affects the electric motor sigmatism period and user39。s health. Different according to the electric motor structure, May adopt various method to divide into several kinds condition giving a test, And adopt corresponding method to carry out treatment according to whose various different form, Make an electric motor be able to work again securely. Keywords: Electric motor, Routine attention, The electric motor temperature rises, The electric motor vibrates, Rotator malfunction , noise 目錄 緒論 1 第 1章 電動(dòng)機(jī)的日常維護(hù) 1 電動(dòng)機(jī)的日常維護(hù) 1 異步電機(jī)過(guò)負(fù)荷原因 1 正確選用電動(dòng)機(jī)的基本原則 1 電動(dòng)機(jī)的基本技術(shù)要求 1 第 2 章 溫升對(duì)電機(jī)壽命的影響 2 溫升引起的電機(jī)故障 2 軸承卡死 2 線圈燒毀、欠相 2 影響電機(jī)溫升的原因與降低溫升的方法 2 電機(jī)發(fā)熱故障的排除 2 第 3 章 中型異步電動(dòng)機(jī)振動(dòng)原因簡(jiǎn)析 3 各類振動(dòng)的特征及頻率 3 轉(zhuǎn)子機(jī)械不平衡引起的振動(dòng) 4 定、轉(zhuǎn)子偏心引起的振動(dòng) 4 引起電機(jī)軸向振動(dòng)的因素 5 第 4 章 電動(dòng)機(jī)轉(zhuǎn)子故障的分析 5 轉(zhuǎn)子故障的原因及檢查方法 5 鑄鋁轉(zhuǎn)子的檢查 5 銅條轉(zhuǎn)子的結(jié)構(gòu)和故障的原因 5 銅條焊接轉(zhuǎn)子的故障檢查 6 繞組的材料 6 轉(zhuǎn)子故障的處理 6 銅轉(zhuǎn)子繞組 6 鑄鋁轉(zhuǎn)子繞組 6 第 5 章 電機(jī)噪聲 7 電機(jī)噪聲的分類 7 電磁噪聲 7 機(jī)械噪聲
