Let s get a new one, the fan doesn t rotate, how to repair it

The motor of the electric fan only hears a whining sound and does not rotate, which should be caused by improper tightening of the screw and the stuckness of the rotor core when the rotation is installed. Because the gap between the stator and rotor cores of the asynchronous motor used by the electric fan is very small, generally less, the screws should be tightened one by one in the order of the diagonal during general installation, if the diagonal order (but in the order of adjacency) is not used to tighten the screws, it is easy to cause the stator and rotor cores to be stuck, and cause the fault phenomenon that the motor does not rotate. The "whining" sound is caused by the electromagnetic force between the stator and rotor.

Check whether it is stuck, and when you turn the rotor in the case of power failure, you can feel whether it is stuck. It should be noted that do not drive the blades to rotate with your hands when electrified, otherwise it is easy to hurt your fingers in case it is not stuck.

If you turn the rotor when the power is off and you find that the rotor can rotate easily, but the fan does not rotate after powering on, it is most likely due to damage to the split-phase capacitance of the electric fan. Since most of the motors of electric fans belong to single-phase asynchronous motors, in order to make the single-phase asynchronous motor start, it is necessary to access the split-phase capacitor in one of the two windings in its wording, so that the current phase of the two windings is different (that is, the so-called "split-phase"), the capacitance is broken, the single-phase winding can only produce a pulsating magnetic field, and the motor will not be able to start.

Some are less lubricating oil for the electric fan shaft, this can be unplugged in and rotate the blade by hand to try whether it is tight, if it is tight, it may be a lack of lubricating oil, or the 4 screws of the host may be loose and cause the asymmetry of the shaft inside, if the blade is not tight, you can change the starting capacitor to see, change the capacitor to see the capacity, the starting speed of the large capacity will be relatively faster, and it is recommended to change the capacitor to operate the person who understands the circuit, mainly for the sake of safety.

The repair method of the fan does not turn is as follows

1. If the capacitor does not rotate due to serious aging, it can be replaced with a new capacitor of the same model; 2. Due to the internal failure of the electric fan, do not carry out the maintenance by yourself, it is better to contact professional maintenance personnel for maintenance; 3. Due to the fact that the power socket is not energized, you need to replace it with a new socket for attempt. The specific solutions for the electric fan not to rotate are: 1. Replace the accessories, the fan blade of the electric fan is an accessory that is easy to damage, especially the electric fan that has been used for a long time, so replacing the new fan blade in time can effectively increase the wind power and speed of the electric fan.

2. Replace the new motor, the motor is the key factor for the electric fan not to rotate, if the load capacity of the motor becomes worse, it will directly cause the electric fan not to rotate, the motor load is not enough, mainly in the electric fan with a long service life, so you can send it to the electric fan maintenance center for maintenance, or you can buy a new electric fan. 3. Replace the new capacitor, the electric fan will be used for too long and the capacity of the capacitor will become smaller, so it will not be able to drive the electric fan, so you need to replace a new capacitor, and the capacity of the capacitor can be increased by about 20% when it is replaced, which can effectively prevent the problem of the electric fan not rotating.

Due to the serious aging of the capacitor, it can be replaced with a new capacitor of the same model; Due to the internal failure of the electric fan, in this case, it is recommended not to enter the crack balance for maintenance without permission, and it is better to contact professional maintenance personnel for maintenance; Since the power outlet is not energized, it is necessary to replace it with a new one.

If the load capacity of the motor becomes poor, it will directly cause the electric fan not to rotate, and the motor load is not enough, mainly in the electric fan with a long service life, so it can be sent to the electric fan maintenance center for maintenance, or you can buy a new electric fan.

Replace the new capacitor, the electric fan will be used for too long will cause the capacity of the capacitor to become smaller, so that the electric fan can not be driven, so you need to replace a new capacitor, and the capacity of the capacitor can be increased by about 20% when replacing, so that the macro can effectively prevent the problem of the electric fan not turning.

Kiss. Hello fan not turning may be due to the following reasons:1

Power Issues: Check that the plugs and sockets are working properly. 2.

Motor Problems: The motor may have burned out or the wires are loose. 3.

Blade Problem: The blade may be stuck or damaged. 4.

Board Issues: The board may be faulty. In view of the above reasons, you can try the following maintenance methods for the ruler and the ante

1.Power supply problems: Check if the plug and socket are working properly, and try to replace the socket or plug.

2.Motor problem: Open the electric fan housing and check whether the motor is damaged or the wires are loose.

If there is damage, the motor needs to be replaced or the wires need to be repaired. 3.Wind Blade Problem:

Open the fan housing and check if the blades are stuck or damaged. If necessary, the blades can be cleaned or replaced. 4.

Board Problems: Check the board for faults and replace or repair the board if necessary. It should be noted that when carrying out electric fan maintenance, it is necessary to ensure the safety of the guard.

Before disassembling the fan, you need to unplug the power supply to avoid electric shock accidents. At the same time, when carrying out electric fan repairs, you need to follow the corresponding operating steps to avoid causing more damage. If you are unsure how to carry out an electric fan repair, it is advisable to seek the help of a professional.
