The motor is the driver of the garage door. If it is in a bad mood and doesn't work well, you can only work in a hurry, and it will bring some unnecessary losses to your enterprise,
1. The air gap between the stator and rotor is very small, which easily leads to the collision between the stator and rotor; If it is found that the bearing of the quick accumulation door is worn, it should be replaced in time. The end cover should be replaced or brush plated. The relatively simple treatment method is to insert a sleeve into the end cover.
2. Abnormal vibration or noise is easy to cause motor heating, which belongs to the vibration caused by the motor itself, most of which are caused by poor dynamic balance of the rotor, poor bearing, bending of the shaft, different shaft axes of the end cover, base and rotor, loose fasteners or uneven foundation and improper installation of the motor, or the mechanical end
3. If the bearing does not work normally, the grease should be changed once after 3000-5000 hours of operation.
4. When the power supply voltage is too high and the excitation current increases, the motor will overheat. When the three-phase voltage is asymmetric, that is, when the voltage of one phase is too high or too low, the motor will overheat due to the excessive current of one phase. At the same time, when the torque decreases, the motor will emit a "buzz" sound, and the winding will be damaged after a long time. The power supply voltage of the generator shall not exceed ± 10% of the rated value, and the difference between the three-phase power supply voltages shall not exceed ± 5% of the rated value.
Therefore, in the selection of motor matter, can not be taken lightly, common good quality brands are: sej fast door motor, sew, grand, baikuojie, etc., so that it can be useful to avoid the abnormal vibration of fast stacking door.
