This issue mainly boils down to an imbalance. Your ceiling fan's imbalance can be a result of several reasons including loose screws that secure the blades, or uneven blade spacing. Misaligned blades disrupt the equilibrium of your fan and cause wobbling.
The best way to fix this is to take down the blades and accurately weigh them and glue on weights so they are all the same. I used small washers on mine and put them halfway along the blade. Another way is to put blades of the same weight opposite each other.
One of the most frequent causes of wobbling are blades that are uneven or improperly installed. Make sure that all of the blades are tightly screwed into the blade holder and that the screws holding the blade holder to the fan flywheel are also secured. Make sure that the area is dust-free and attempt running the fan.
The most common cause is a dirty or clogged filter. This can cause the fan to struggle to draw in air, resulting in the fan speed fluctuating. Another possible cause is a faulty fan motor or capacitor, which can cause the fan to run at different speeds.
Malware (virus, spyware, trojans, and so on) can cause a computer fan to run constantly due to an overload on the processor (CPU), this in turn causes the fans to run constantly and fast.
Oftentimes, your ceiling fan blades might get damaged contributing to an imbalance in the fan. It might also happen that the blades of an old fan begin making . Replace any blades that have a bent area as soon as possible since they have the possibility of injuring anyone present in the room.
This is because of inertia. The fan blades have been set in motion and they want to keep moving. This is why they continue to spin even though the power is off. Without inertia, the fan would simply stop as soon as the power was cut off, but that's not what happens due to the principles defined by this law.
Wobbling can stem from a variety of causes, including blades warping, loose screws, and faulty installation. While Hunter fans are built to be wobble-free, incorrect installation can cause an issue with imbalance or wobbling.
While a small wiggle in ceiling fans up to 1/8-inch is normal, more than that can indicate a larger problem. A noisy, off balance ceiling fan can lead to inefficient operation and excessive wear on the fan motor.
Misaligned Blades
Blade misalignment means one or more of your blades are spinning at a different height than the other. The draft from the misalignment of blades distorts the airflow and wobbles the blades. Prolonged misalignment can cause the blade screws to loosen and the blade holders to warp.
Unbalanced blades can cause the fan to wobble, leading to vibrations that generate noise. Properly balanced blades ensure smooth rotation and quiet operation.
If the blades are not even, then the fan may wobble and rattle during use. To fix this issue, measure the vertical distance from the tip of each fan blade to the ceiling. If the measurements for all blades are not equal, then you can make slight adjustments by tightening the mounting screws on the motor housing.
However, if you're looking to simply target a specific area for cooling, then keeping it static is your best bet. When temperatures rise, keeping the air moving around will help make the room feel more comfortable and fresher due to a gentle breeze.
From non-spinning blades, poor lubrication, and to a noisy fan, electric fans have very common problems that you can fix yourself. Repairing an electric fan may be hard at first look especially if the problem is rooted from the motor or if any cleaning does not do the job.
The blades should be rotating from left to right (clockwise). You can also stand directly under the fan while it's on high speed; whichever way you feel the least amount of cool air is the correct direction.
Tape a dime to the middle of each blade and, one at a time, crank the fan up to high. Eventually you'll pinpoint the one whose wobble begins to weaken. Then move the coin up and down the blade, trying heavier coins if you need to, until you find the perfect balance.
Fans that are left on constantly can use more electricity than they should, and their blades will become dull quickly, even without being used. – Clean it regularly. The one major risk that you have when running an electric fan all day long is dust and debris building upon its surface.
Answer and Explanation:
The electric fan continues to rotate for some time after the current is switched off due to rotational inertia force. This situation of the electric fan can be explained more by Newton's law of inertia that states that a rigid body in motion stays in motion until an external force is applied.
Faulty Capacitor:
A capacitor is responsible for starting and spinning the fan. It also regulates the fan speed by storing and releasing electrical energy in a controlled manner. If the capacitor stops working properly, it can interfere with the fan's speed. Check if the capacitor is broken or blown.
Dust and Dirt Build-Up on Fan Blades
Ceiling fan blades gather dust over time; this dust adds extra weight and creates an uneven resistance. Both these factors combined make the fan work harder and ultimately slow it down. Regular cleaning does more than merely improve the fan's speed.
In summer due to high temperature of the environment , resistance of the winding of a fan increases, compare to low temperature in winter. Due to higher winding resistance current will decrease and fan rotates slower in summer compare to in winter .
