Ceiling fan slow speed, what is the reason and how to deal with it? 20

The main contradiction is that the capacitance has been used for a long time, and the capacity has become smaller. It is recommended to replace it with a new capacitor of the same capacity. There are also the following reasons:

1. The governor is damaged

If it is a newly bought ceiling fan and you find that it rotates slowly, it may be that the governor is broken.

2. The bearing lacks oil

It is also possible that the ceiling fan has been used for a period of time and the bearing is short of oil, which will also affect the speed. At this time, you can add some butter, if it is a short circuit between turns, the motor will overheat and need to be rewound.

3. Fan blade problem

Take a closer look at whether there is a problem with the fan blades, such as whether they are deformed, and if there is a serious deformation, it will also affect the speed.

The fan will be used more and more slowly

The motors of the most advanced household ceiling fans on the market are capacitive motors (single phase). Originally, the single-phase motor has no starting torque, if there is only the main winding coil, then each start must be added to make it start to rotate, and then rely on inertia to cross the neutral plane to maintain operation.

Therefore, a secondary winding coil is added, and the capacitors are connected in series, which is the phase shift of the current. The magnetic field generated by the current after this phase is the starting moment. And in the process of operation, the rotating torque has been maintained to ensure that the motor rotates effectively.

If the capacitance is small, the torque will be small, and the motor will be weak and slow. The larger the capacitance, the greater the torque, and the faster the rotation.

Due to the long period of use, the capacitance decreases, resulting in a decrease in rotational speed.

After the ceiling fan is used for a long time, its speed may slow down, whether this is a normal phenomenon or the ceiling fan is broken, let's find out.

What is the reason for the slow speed of the ceiling fan - the cause of the bad bearing and the solution.

If it is a new one, it may be that the ceiling fan governor is broken, if the fan bearing is short of oil, then you can add some oil, you have to use butter, if it is a short circuit between turns, the motor will overheat, and it will be rewound. The judgment of the bearing problem can listen to the sound of whether the bearing has a problem, and the bearing has a problem to call professional maintenance personnel for maintenance.

Most household appliances are powered by single-phase power supply, but electrical appliances with electric motors must be powered by two-phase or more power supply, what should I do? The designer has long thought that in the single-phase circuit, connect a large capacitor in parallel, because the large capacitance has a hysteresis effect on the current for the AC power supply, and the circuit with the capacitance is 90 degrees after the current of the circuit without the capacitance, so that the original one-phase input becomes two-phase, and the motor can work normally.

The household appliances we use are based on this principle. If the capacitance value becomes smaller or the oil lack friction is large or the inter-turn short circuit is large, the capacitance value becomes smaller, and the capacitance value can be increased appropriately, but not too much, otherwise the temperature of the motor will rise and affect the life of the motor. This is the synchronous motor speed is determined by the frequency of the power supply, if there is no page 100 rpm, after installing the blades is also 100 rpm, if you install a few more leaves, the load is too heavy, the motor can not start, the spring continues to repeat to help start.

In addition, slow rotation speed is not necessarily a problem of capacitance and bearing, capacitance is to ensure that the fan can rotate in the pre-rotation direction. Check whether the fan blade is deformed, the reduction of the wind surface will affect the air volume, and check whether the governor is not in good contact, so that the gear is in a low gear position.

What is the reason for the slow speed of the ceiling fan - the solution to the fan blade problem.

Take a look at whether there is a problem with the fan blades - turn off the ceiling fan and carefully check whether the fan blades are deformed, if they are seriously deformed, it will also affect the speed, but this will most likely not, unless it is newly purchased, and this situation may occur during the consignment process.

1. Governor: If you find that the ceiling fan at home rotates slowly, there may be a problem with the governor.

2. Bearing: There is a bearing when the ceiling fan rotates, if there is a stuck problem or lack of oil, it will also affect the speed.

3. Voltage: The reason why the ceiling fan can rotate is to rely on a certain voltage, but if the voltage does not reach the standard, it will cause it to fail to start or rotate slowly.

4. Fan blade shape: If the fan blade has the problem of deformation, when there is serious deformation, it will also lead to a relatively slow speed.

5. Capacitance: Nowadays, many electrical appliances are one-way power supplies, if the capacitance capacity of the ceiling fan becomes small or insufficient, it will cause damage to the motor, which will affect its speed.

6. Motor: If there is dust accumulation in the motor of the ceiling fan, it will also lead to the wear and tear of the parts, resulting in the slow speed of the ceiling fan.

This is the synchronous motor speed is determined by the frequency of the power supply, if there is no page 100 rpm, after installing the blades is also 100 rpm, if you install a few more leaves, the load is too heavy, the motor can not start, the spring continues to repeat to help start.

1.Add some lubricating oil to the bearings.

2.Replace the capacitor, it can definitely be solved.

In addition, the slow rotation speed is not necessarily a capacitance problem, the capacitance is to ensure that the fan can rotate in the pre-rotation direction. You check the coils and bearings, and there is no problem.

Check whether the blades are deformed, and the reduction of the wind surface will affect the air volume. Also check whether the governor is not in good contact and puts the gear in the low gear position

Take it apart, clean it up, and add some oil.

The reasons for the slow speed of the ceiling fan are as follows:

1. If you find that the ceiling fan at home rotates slowly, there may be a problem with the governor.

2. The other is that there is a bearing when the ceiling fan rotates, if the pure closed fruit is stuck or there is a lack of oil, it will also affect the speed.

3. The reason why the ceiling fan can rotate also depends on a certain voltage. However, if the voltage is not up to standard, it will not start or rotate slowly.

4. There is another problem, the fan blade has the problem of deformation, and when there is serious deformation, it will also lead to a relatively slow speed.

5. It also has a lot to do with the capacity of the capacitor, because many electrical appliances are one-way power supplies, if the capacitor capacity becomes small or insufficient, it will cause damage to the motor, which will affect its speed.

6. In addition, if the motor of the fan is sold with the accumulation of dust, it will also lead to the wear and tear of the parts.

The slow speed of the ceiling fan is a problem with the circuit.

The power supply voltage is lower than the rated voltage of the ceiling fan, which will cause the ceiling fan to rotate slowly. This can be solved by replacing the power or resistance source or increasing the voltage. Dust or oil accumulation on the fan blades will increase the wind resistance, resulting in slow fan speed.

The leaves can be cleaned with detergent or a damp cloth. Prolonged use will cause the fan bearing to deteriorate, increase friction, and slow rotation. Bearings or entire ceiling fans can be replaced.

Damaged or aging fan capacitors will cause the ceiling fan to rotate slowly, which can be solved by replacing the capacitors. Problems with the fan circuit, such as aging circuit boards, poor connection wiring, etc., can also cause the ceiling fan to rotate slowly. The circuit can be inspected and repaired or replaced.

Regular maintenance of ceiling fans can guarantee their longevity and safety. Clean the ceiling fan blades regularly, check the power supply and installation of the ceiling fan, and ensure the normal operation of the ceiling fan.

Precautions for using ceiling fans

1. Installation location: The ceiling fan should be installed at a position above the ground to avoid direct contact with the ceiling fan blades. At the same time, the ceiling fan should be installed in such a way that it is kept at a certain distance from the surrounding items, so as not to touch the surrounding items when rotating.

2. Power wiring: The power wiring of the ceiling fan should be carried out by professionals to ensure that the wiring is correct and stable, so as to avoid electrical accidents.

3. Wind direction adjustment: Different seasons and use occasions need different wind directions, and the wind direction of the ceiling fan should be able to be adjusted at any time. Normally, in summer, it needs to rotate in a counterclockwise direction so that the wind can form a downward cold wind; In the winter season, it needs to rotate in a clockwise direction so that the wind can form an upward warm wind.

4. Safety precautions: When using the ceiling fan, you should pay attention to safety and avoid reaching out to touch the blades of the ceiling fan when the ceiling fan is rotating, so as to avoid accidents. At the same time, the use time of the ceiling fan should also be appropriate, as long-term use will lead to overheating of the appliance and increase the risk of electrical accidents.

Causes and solutions for slow ceiling fan speed.

1.Preliminary examination.

There are many reasons why the ceiling fan is slow, and there are some basic checks such as keys that need to be done first. Check the fan for looseness or noise, tilting or imbalance. If the fan is unbalanced, it may cause the fan to vibrate, which in turn will cause the fan to spin slower.

In addition, you should also check whether the power supply and plug are connected correctly and whether the power supply is normal.

2.accumulation of dirt and dust.

Using ceiling fans for long periods of time can lead to the accumulation of dirt and dust, which can hinder the operation of the fan and cause the speed to slow down. Therefore, it is advisable to clean the ceiling fan regularly. Use a soft cloth to clean the fan, be sure to unplug the mains if water is needed, and make sure the fan is dry and ready to plug in.

3.Capacitor short circuit.

The capacitor of the ceiling fan is one of the key components to control the speed of the ceiling fan. If the capacitor is short-circuited, it will cause the fan to speed slower. In this case, the capacitor needs to be replaced.

However, since the capacitor is at a high voltage, be sure to disconnect the power supply when replacing the capacitor and make sure not to touch the capacitor pins to avoid electric shock.

4.Motor failure.

If the ceiling fan is still slow, it may be due to a faulty motor. When the motor fails, the fan tends to rattle or screech. At this point, the motor needs to be replaced. But the motor is one of the most critical components of the ceiling fan, which needs to be replaced by professionals.

5.Conclusion.

There are many reasons for the slow speed of ceiling fans, some can be solved by themselves, and some need professionals to repair them. Regular cleaning and maintenance is the most basic way to keep your ceiling fan in good working order. It is important to emphasize that before any inspection or maintenance of the ceiling fan, be sure to cut off the power supply and ensure safety.

1. The governor is broken.

If it is new, the ceiling fan governor may be broken and you need to find a merchant to replace it.

2. Insufficient bearing oil.

If the fan bearing is short of oil, you can add Chi Xiang Cong to point oil (butter is required), if the banquet is a short circuit between turns, the motor will overheat, and it needs to be rewound. If there is a problem with the bearing, you can hear the sound, if there is a problem with the bearing, you need to ask a professional maintenance personnel to repair it.

3. The capacitance capacity decreases.

The capacitance value of the capacitor becomes smaller or the friction caused by less oil or short circuit between turns is large, and the capacitance value of the capacitor becomes smaller, and the capacitance value of the capacitor can be increased appropriately, but not too large, otherwise the temperature of the motor will rise, which will affect the life of the motor. In addition, it is also possible that the capacitance at low speed is to ensure that the fan can rotate in the pre-rotation direction. Check whether the fan blades are deformed, the wind surface is reduced, which affects the air volume, and the code cherry is also checked whether the governor is in poor contact, so that the gear is in a low gear.

There are several reasons why ceiling fans rotate slowly:

1. The rotor (the standard bearing should be called) is short of oil, it is recommended to turn off the power, stand at a certain height, and pull back the fan blade with your hand to see if the rotation is very smart, such as the finch Changguo swaying, and even accompanied by the sound of chirping wow, then, add some lubricating oil to the rotor in the middle of the ceiling fan, and then turn on the switch after absorbing the moisture, which should be able to restore the speed.

2. The switch box is the box that adjusts the speed on the wall. Buy a new one, install it, try a draft of the town, and you can restore it.

3. If there is a problem with the fan blade, it is best to turn off the ceiling fan and carefully check whether the fan blade is deformed, if it is seriously deformed, it will also affect the speed. The labor is so big, it is completely necessary to spend some money to repair it.

4. The capacitor is broken, and the smaller the capacitor capacity is when the fan motor winding is normal, the slower the fan speed. After the capacitor is used for a long time, the capacitance dielectric and dielectric coefficient d will change, and the capacitance performance will be reduced. When the capacitor is used for a long time, the capacitive dielectric decreases, and at the same time, the dielectric coefficient also decreases.

Pay attention to the following points in the use of ceiling fans to keep the speed slow:

1. It is not suitable to work for a long time.

After two to three hours of continuous operation, the ceiling fan should be shut down to dissipate heat before use, otherwise the parts may overheat and burn.

2. Regularly inspect the ceiling fan.

The ceiling fan should check whether the connection of each part of the boom and the hook are good and firm, and whether the boom, screws, terminal blocks, blades, etc. of the ceiling fan are loose or corroded, rusted, cracked, deformed and other abnormal conditions. The screws and pins of ceiling fans can be checked every two to three years for their wear procedures, and the severely worn parts can be replaced in time.

3. It is forbidden for other objects to touch the ceiling fan in operation.

When the ceiling fan is running, nothing can be thrown underneath the ceiling fan; Do not jump under the ceiling fan, users with a low ceiling should pay more attention; It is also forbidden to hold up infants and toddlers under the running ceiling fan. In order to prevent the human body and other objects from touching the running ceiling fan, the machine will be damaged.
