The reason for the unstable speed of EC centrifugal fan

Among the types of high-efficiency and low-energy fans, EC centrifugal fans are particularly outstanding. This type of fan has been highly praised since its launch, but some users have also reported that there is instability in speed when using EC fans. What is the reason for this? Let's see what the experts have to say.

As an efficient and energy-saving product, the EC fan uses a permanent magnet synchronous motor as its motor, which can automatically adjust the fan speed and adapt to different working environments and conditions.

Through precise electronic control system operation, EC fans can not only ensure efficient operation of the fans, but also ensure their stability, effectively avoiding some possible fault situations. The stability and reliability of this type of fan greatly increase users' confidence in using it, allowing them to use this product with more peace of mind.

However, when using it, attention should be paid to its working environment to avoid excessive load or situations where the required air volume exceeds its rated air volume. If the EC centrifugal fan is used normally in its working environment but still experiences unstable speed, the reasons may be the following.

1、 Voltage issue. When using motor-driven equipment, it is possible that the motor speed may be unstable due to unstable power supply voltage or aging circuits. At this point, we can solve the problem by changing the power interface, replacing the power supply, or replacing the motor controller.

2、 The rotor is unbalanced. During the use of the fan, if the rotor's center of gravity is unbalanced due to manufacturing or other reasons, it is also prone to unstable speed. In this case, maintenance and upkeep of the equipment are required, and the rotor needs to be recalibrated to eliminate any imbalance.

3、 Damage or wear. The mechanical components inside the EC centrifugal fan may experience unstable speed due to friction or wear after prolonged use. At this point, we can replace damaged parts or perform minor mechanical repairs to solve the problem.

Through the exploration of these reasons, it can be found that for the unstable speed of EC fans, users should be actively guided to explore the causes of the problem and solve it through technical means or maintenance.

At the same time, we should also pay more attention to quality control and maintenance in the manufacturing and use of EC fans to avoid the above situations.

As a new type of fan equipment, EC centrifugal fan can be eliminated and solved if its speed is unstable during use. When encountering situations where the speed is unstable, one should remain calm, analyze carefully, identify the root cause, and then develop solutions. By handling the issue correctly, the problem can be quickly resolved.
