The main reason why the fast door can work at high speed is still due to the motor in its electronic control system. The motor plays an important role in the fast door. As long as the stable electric control system is adopted, the fast rolling shutter door can work reliably and stably. In the use of the process, it is inevitable that there will be failures, the following is Jinan Fuqiang door industry to sum up the common faults in the use of fast doors and adjustment methods, I hope to help our small partners, help you!

快速门电机常呈现的缺点有两种，它们分别是快速门电机旋转方向过错与电机电流耗费较大且隆隆作响。呈现快速门电机旋转方向过错的原因，有两种，它们依次为电机接线过错与旋转方向过错，对其解决方案则是替换两个相线即可。

There are two disadvantages of the fast door motor, they are the fault of the rotation direction of the fast door motor and the motor current consumption is large and rumbling. There are two reasons for the fault of the motor rotation direction of the fast door. They are the motor wiring fault and the rotation direction fault in turn. The solution is to replace the two phase lines.

一个原因是，电机电压下降，我们只要将电源线截面增大即可。于呈现噪声过大的原因则有三种状况.主要便是球轴承被沾污、曲解变形或者是受损。一旦发现是这个原因，我们应立即将电机纠正，并检查求轴承，必要时还需要增加或者是替换润滑脂，其次是旋转部件颤抖。找出颤抖原因，并及时将其排出，必要时打扫不平衡差度;毕竟则是散热空气通道中有异物。我们只要将散热空气通道中的异物整理洁净即可。

One reason is that the motor voltage drops, we just need to increase the cross-section of the power line. There are three reasons for excessive noise. The main reason is that the ball bearing is contaminated, distorted or damaged. Once it is found that this is the reason, we should immediately correct the motor and check the bearing. If necessary, we need to add or replace the grease, followed by the shaking of the rotating parts. Find out the cause of shaking, and timely discharge it, if necessary, clean the imbalance degree; after all, it is the foreign matter in the cooling air channel. We only need to clean the foreign matters in the cooling air channel.

还有一个原因主要快速门在于当呈现快速门电机隆隆作响或者是电流耗费较大时，导致这一现象的原因是制动器不开释、绕组损坏或者是转子触碰绕组。若制动器不开释，我们可以依据规定的有关制动器上的缺点进行调整。而若呈现绕组损坏或者是转子触碰绕组等事端时，我们则应将快速门电机送到专门修补厂进行修补。

Another reason is that when the fast gate motor rumbles or the current consumption is large, the cause of this phenomenon is that the brake does not release, the winding is damaged or the rotor touches the winding. If the brake does not release, we can adjust the brake according to the national regulations. If the winding is damaged or the rotor touches the winding, we should send the fast door motor to the special repair factory for repair.

快速门能够高速运行的，主要还是要要归功于其电控系统。电控系统在快速门中有着关重要的作用，只有稳定的电控系统，才能保证快速门能够可靠稳定的运行。

Fast door can run at high speed, mainly due to its electronic control system. The electronic control system plays an important role in the fast door. Only a stable electronic control system can ensure the reliable and stable operation of the fast door.

在运用快速卷帘门时总是会由于一些而形成快速门无法正常运作。运用快速门电机时可能会呈现转速剧烈下降或者是噪声过大的问题。其间呈现转速剧烈下降的原因有两种，首要是负荷过载。我们可以选用减少负载或者是调换更大功率电机的处理方式。

In the use of fast rolling shutter doors will always be due to some and the formation of fast doors can not work normally. When using the fast gate motor, the speed may drop sharply or the noise is too high. There are two reasons for the sharp decline of speed, the first is overload. We can choose to reduce the load or switch to a higher power motor.
