Fan chandelier spins very slowly

Do you know why the fan chandelier spins very slowly?

Electric fans are the most common household appliances in our lives, and they play a very important role in summer. There are also many types of electric fans. The most common ones are shaking head fans, floor fans, and table fans. Ceiling fans, etc. Ceiling fans are also very common. However, many friends found that the electric fan will turn slower and slower after the ceiling fan has been used for a long time. And why does the ceiling fan turn slower and slower? Next, I will explain it to you in detail.

What is the reason for the slow speed of the ceiling fan?
1. The governor is broken
If it is a new one, the governor of the ceiling fan may be broken.
2. Bearing lack of oil
If the fan bearing is short of oil, you can add some oil (you need to use butter). If it is a short circuit between turns, the motor will overheat, and you need to rewind it. If there is a problem with the bearing, you can listen to the sound. If there is a problem with the bearing, you should call professional maintenance personnel to repair it.

3. Capacitor capacity drop
Most household appliances are powered by single-phase power supply, but electrical appliances with electric motors must be powered by two or more phases of power supply. What should I do? Capacitor, because the large capacitor has a hysteresis effect on the current for the AC power supply (the circuit with capacitor is 90 degrees behind the current of the circuit without capacitor), so the original one-phase input becomes two-phase, and the motor can work normally. . The household appliances (single-phase) we use are all based on this principle.

The capacitance value of the capacitor becomes smaller or the friction is large due to lack of oil or the short circuit between turns, and the capacitance value of the capacitor becomes smaller, and the capacitance value can be appropriately increased, but it cannot be too large, otherwise the motor temperature will rise and affect the life of the motor. This is a synchronous motor, the speed is given by the frequency of the power supply is determined. If the leaf is not installed at 100 rpm, it will be 100 rpm after the blade is installed. If a few more leaves are installed, the load will be too heavy and the motor will not start. The spring will help start repeatedly.

In addition, the slow speed is not necessarily a problem with the capacitor and the bearing. The capacitor is to ensure that the fan can rotate in the pre-rotation direction. Check whether the fan blade is deformed, and the reduction of the wind surface will affect the air volume. Also check the governor

Whether the contact is not good, so that the gear is in the low gear position.
4. There is a problem with voltage sharing.
5. Ceiling fan blade problem
Turn off the ceiling fan and check carefully whether the fan blades are deformed. If the deformation is serious, it will also affect the speed, but most of them will not. Unless it is a new purchase, this situation may occur during the shipping process.

The above is what EJLED shared with you about the slower and slower rotation of the ceiling fan. I hope our sharing will be helpful to you. When the ceiling fan is used for a long time, it will appear slower and slower. But no matter what, this problem is unavoidable, so you can only restore the previous speed of the ceiling fan by finding the reason for the slow rotation of the ceiling fan and making some adjustments to the ceiling fan for such reasons. The above sharing has already told you in detail the reasons for the slow rotation of ceiling fans and how to deal with these problems.
