What is the reason why the speed of the electric fan slows down? What is the reason for the slowdown

The cause of the electric fan itself may include that the blades may have been too long, and the resistance in the motor has become large, causing the blades to not rotate properly. The overheating of the fan leads to the deterioration of the load capacity of the motor, resulting in its inability to rotate, the internal protection device of the motor is overheated and short-circuited, the starting capacitance capacity of the electric fan is small, and the axial clearance of the rotating shaft of the electric fan is too large.

Related information. Today's electric fans have changed the traditional image in people's impressions, and are more personalized in appearance and function. Computer control, natural wind, sleep wind, negative ion function, etc.

It belongs to air conditioners, and is also used by many electric fan manufacturers, adding more practical functions such as lighting and mosquito repellent. These eclectic and versatile products indicate the development trend of the entire electric fan industry.

In the era of pursuing individuality, fashion and sophistication, consumers seem to have a soft spot for petite and cute home appliances. As a result, cute-looking, brightly colored, and petite box-shaped fans were born along with various portable electric fans. The housing and blades of these electric fans are plastic, making them very light overall.

With their petite size and beautiful colors and appearance, these fans were very popular as soon as they were launched.

The slower speed of the electric fan is the cause of the capacitor, and under normal circumstances, just change the capacitor. Moreover, the rotor of the motor has garbage and cannot rotate, so sometimes it is enough to add some sewing machine oil. If it doesn't work, it's useless.

Note, there are many people who can't get the things inside the motor, and they can't be repaired if they are sent for repair. Buy one from the new, the current electric fan ** is not high (expensive)!

If the speed of the electric fan is slow, it is likely that there is a problem with the motor inside, or there may be a problem with the gear, or there is something else inside.

What is the reason why the speed of the electric fan slows down? There are many reasons why the fan speed slows down, such as insufficient power or a problem with the grade adjustment of the fan, or ask a professional person to take a look, or ask the after-sales customer service.

There are many reasons, the supply voltage, the fan bearing.

Slightly slow, there are two reasons for the capacitance to become smaller, the rotation is not flexible, and the winding is too slow.

If the speed of the electric fan is slow, the reason may be the lack of oil in the bearing, of course, it is not ruled out that the voltage is not enough.

The reason is that one of the capacitors in the electric fan is broken!

1. There are too many fan blade stains, and the internal resistance of the motor becomes larger, resulting in the slow speed of the electric fan.

2. Caused by fan overheating, the load capacity of the motor becomes poor, causing the electric fan to rotate slowly.

3. The shaft is worn and produces debris, resulting in the slow speed of the electric fan.

4. The starting electric heat of the fan becomes smaller, which cannot drive the load, resulting in a slower speed.

What are the precautions for the use of electric fans?

1. Pay attention to the position of the electric fan.

The position of the electric fan and the human body should not be too close, if it is too close, the gap between blood circulation and sweat circulation will be too large, and if you blow like this for a long time, all organs of the human body will feel tired, and the whole body will feel uncomfortable. The best position of the electric fan is about 2 meters away from the human body, so that the wind is softer and more even.

2. Don't blow directly to people for a long time.

The electric fan must not blow directly on people, otherwise it is easy to cause a cold, and you will have sore arms and legs the next day. Therefore, we should set the electric fan to rotate, so that it will be better and the damage to the ** body will be less.

3. Set the wind speed.

The wind speed of the electric fan should not be too large, so as to ensure that the human body has an adaptation process. The indoor wind speed is better controlled in a small block, especially in the room with good ventilation and in the place where there is excessive wind, the wind speed of the fan should not be too large.

4. Try to time the electric fan.

When blowing a fan at night, don't blow it all night, it's not good for your body. Most fans have a timing function, so try to time the electric fan as much as possible, and as long as you fall asleep, you won't feel hot. This not only saves electricity, but also is good for the body.

5. Protect the fan blades of the electric fan.

Fan blades are a key component of electric fans, so when Shinkin installs, disassembles, scrubs or uses, it must be protected to prevent deformation. In particular, it is important to prevent children from inserting foreign objects, such as pencils, into the fan.

How long does a fan last?

The normal service life of an electric fan is 16 years. Electric fans produced by regular manufacturers generally have to undergo aging tests before a new product is put on the market, and some will go through permanent life tests. So there was no problem at all when it was opened overnight.

Turning on electric fans and other electrical equipment for a long time will increase equipment loss, and it is easier and faster to make the equipment aging and broken, but don't turn on and off electric fans and other equipment frequently, because when turned on, the voltage will increase suddenly, and it will also reduce the life of the equipment, such as going to the toilet, it may only take a few minutes, so there is no need to turn it off.

1. After a long time of fan, the lubricating oil in it has dried up, add some oil. Add oil to the bearing part, turn on the fan and rotate it slightly several times to keep it lubricated, and now most of the fan bearings are not made of oil-containing copper, Xunshi is easy to lose oil, in fact, it is only one or two dollars of cost.

2. If the starting capacitor is faulty, replace the capacitor of the same specification, and the capacitor must be replaced with a capacitor of a unified specification and brand. In case of unnecessary failures. The probability of such failures is generally relatively small.

3. If the motor itself is faulty, and there is a short circuit and leakage phenomenon inside, replace the motor directly or rewind it (the labor cost is high, it is better to go directly to the market to buy a motor).

Related Notes:

As far as the use of the fan itself is concerned, the electric power of the fan with large blades is large, and the power consumption of the electric fan is proportional to the speed of the fan blades. For example, the power consumption of a 400 mm electric fan is 60W when using a strong wind, and the power consumption of a slow gear is only 40W, and the power consumption of the fastest gear of the same electric fan is 40% different from the most Hengchang Yu slow gear. When the air volume meets the requirements of use, try to use a light breeze or stroke.

When in use, it is best to place the fan next to doors and windows to facilitate air circulation, improve the cooling effect, shorten the use time, and reduce power consumption.

1. The fan blades are too dirty, resulting in the imbalance of the fan blades, and the speed of the car is unstable. Dust cleaning fan blades.

2. The fan shaft has impurities or oil stains for a long time, hair and so on, which affects the instability of the speed.

3. The bearing in the fan is in disrepair, or the fan blade is eccentric, resulting in bearing wear or excessive clearance, and it can be replaced.

4. The working environment of the fan is not good, resulting in rust and wear of the bearing, directly disassemble the fan and pull the bearing out with a puller, and replace the new bearing with a closed wheel. The old bearings that are not replaced with new oil will not be used for a long time. After all, the price of inviting a master is not low, so it is simply solved at one time.

The speed of the electric fan is very slow, and it may be that the fan plug is not plugged in properly; It's also possible that the fan switch isn't fully turned on; It is also possible that the fan blade is too long, and the internal resistance of the electric fan motor becomes larger, resulting in the fan blade being unable to rotate normally; It is also possible that the fan overheating causes the load capacity of the motor to deteriorate, resulting in the inability to rotate; It is also possible that the starting capacitance capacity of the electric fan becomes smaller, and the axial clearance of the electric fan shaft is too large, which will also cause the speed problem of the electric fan; It can also be caused by the friction caused by the wear of the shaft and the debris generated by oil roasting and stickiness.

The solutions to the slow speed of the electric fan are: first, the electric fan shaft should be removed, and then cleaned with clean water (which can be washed with a cloth or brush and other detergent), but can not use sharp objects such as blades and sandpaper, the smoothness of the shaft must not be damaged, and when there are stains around the bearing (the prototype is a center device with marbles), you can also wipe it clean with a paper towel, and then restore it; It can also be taken to a dedicated staff for repairs.
