This problem is common in many homes. The electric voltage is 220-230 volts, the meter also shows correct, yet the fan rotates slowly. There is less wind and there is discomfort in the heat. People think that maybe the electricity is weak, but in reality there are many simple reasons why the fan runs slowly even if the voltage is fine. In this article we will understand in simple language why this happens and what can be done.
1-The most common reason is fan motor capacitor To get spoiled. A capacitor is a small device which helps in giving the correct speed to the motor. It becomes weak with time or due to heat. Even if the voltage is correct, the capacitor does not work properly, so the fan rotates slowly. Sometimes the capacitor dries up or bursts. It is easy to change and is also cheap.
2-Second big reason dust and dirt. A lot of dust accumulates on the fan blades and inside the motor. This dust makes the blades heavy and puts extra load on the motor. The result is that the fan runs slowly. While cleaning the house, cleaning the fan is often forgotten. It is very beneficial to clean the blades with a wet cloth and remove the dust around the motor.
3-The third reason is bearing problem. The fan motor has bearings that allow the shaft to rotate smoothly. Due to prolonged use or drying of the oil, the bearing gets stuck. Then the fan also makes noise and the speed also reduces. Sometimes adding grease to the bearing helps, otherwise it has to be replaced.
4-There could be a fourth reason wiring or connections Of. The main voltage in the house may be correct, but the wires reaching the fan may be loose or the joints may be weak. In such a situation the fan does not get full current. Loose screws or old wires in the switch board also cause problems. Speed may also remain low due to regulator failure. Many people keep the regulator on full but still the fan runs slowly, then it is necessary to check the regulator.
5-fifth reason fan life And there is wear and tear. After running an old fan for years, the winding of the motor becomes weak. Due to short in the winding or poor insulation, the motor is not able to show full power. Even if the blades become crooked or the balance is disturbed, the fan runs slowly and hesitantly.
6-Sometimes overloading It also happens. If too many appliances are running on the same circuit, the fan may not receive enough current, even if the voltage appears correct on the meter. This problem is more visible during the summer season.
Keeping all these reasons in mind, you can first check yourself. Clean the fan, replace the capacitor, add oil to the bearing and tighten the connections. If the problem persists then call a good electrician. They will test the motor and tell whether the winding or some other part is bad.
Remember, a slow fan is not just an inconvenience. This can cause the motor to overheat and get damaged quickly. Therefore do not ignore the problem. Regular cleaning and periodic checkups keep the fan running at the right speed for years. Just because the voltage is correct does not mean that everything else is fine. Only small things decide the speed of the fan. With proper care the air in the house will feel fresh and cool again.
