電機是電動車庫門重要的組成部分，電機是十分重要的，沒有了電機，電動車庫門將無法自動開啟，關閉，只能動手開車庫門一樣，依靠人力手動完成開啟或者關閉動作，為了確保電機可以正常的使用，在對車庫門電機進行保養時，有一些要點是大家必須要知道的

　　The motor is an important part of the electric garage door. The motor is very important. Without the motor, the electric garage door will not be able to open and close automatically. Just like opening the garage door, you can only open or close it manually. In order to ensure the normal use of the motor, there are some key points that we must know when maintaining the garage door motor

　　1.車庫門的日常使用環境應保持干燥、不潮濕，電機表面應保持清潔，特別是進風口不應受到灰塵、纖維等雜質的阻礙。

　　1. The daily use environment of garage door should be kept dry and damp, and the surface of motor should be kept clean, especially the air inlet should not be blocked by dust, fiber and other impurities.

　　2、在運行中確保車庫門電機良好潤滑。一般來說，車庫門電機每運行5000小時左右，需要補充或更換潤滑脂。如果發現軸承過熱或潤滑，應及時更換潤滑脂或液壓。更換潤滑脂時，首先拆下舊陶瓷，用汽油清潔軸承和軸承蓋的油槽，然后在軸承內外環之間的1/2、2/3腔內填充潤滑脂。

　　2. Make sure the motor runs well in the garage door. Generally speaking, garage door motor every 5000 hours or so, need to add or replace grease. If the bearing is overheated or lubricated, the grease or hydraulic pressure should be replaced in time. To replace the grease, first remove the old ceramic, clean the oil groove of the bearing and bearing cap with gasoline, and then fill the 1 / 2 and 2 / 3 cavities between the inner and outer rings of the bearing with grease.
            

　　3.一旦發現車庫門電機的振動和噪音顯著增加，電機軸承的壽命就達到了極限。此時應檢查軸承徑向間隙是否達到相應值，及時更換新電機軸承。

　　3. Once the vibration and noise of the garage door motor increase significantly, the service life of the motor bearing will reach the limit. At this time, check whether the bearing radial clearance reaches the corresponding value, and replace the new motor bearing in time.

　　4所示，當車庫門電機的熱保護連續振動時，首先要找出故障的方向，看看電機是否仍超載或保護裝置的整定值過低，只有在排除故障后才能正常運行。

　　4 shows that when the thermal protection of the garage door motor vibrates continuously, the direction of the fault should be found out first to see whether the motor is still overloaded or the setting value of the protection device is too low. Only after the fault is eliminated can the normal operation be carried out.

　　5.如果車庫門電機發生故障，必須將其拆解。轉子可在軸的延長端或非延長端拆卸。如果不需要拆卸風扇，更好選擇更方便從非軸延伸端取出轉子的轉子。如果需要從定子中抽出轉子，應注意防止損壞定子繞組或絕緣。

　　5. If the garage door motor fails, it must be disassembled. The rotor can be removed at the extended or non extended end of the shaft. If it is not necessary to remove the fan, it is better to select a rotor that is more convenient to remove the rotor from the non shaft extension end. If it is necessary to extract the rotor from the stator, care should be taken to prevent damage to the stator winding or insulation.
