What s going on with the rustling sound of the Octavia power on motor?

Octavia's power-on motor has a sizzling sound all the time, it may be that the power cord of this motor is damaged, and the power cord is damaged to occupy the iron, resulting in leakage and squeaking.

It depends on the situation.

2. If it is a new motor and makes a squeaking sound, it may be caused by the fact that the manufacturer did not test the motor when it left the factory, resulting in the grease of the bearing not forming an oil film on the bearing. But after a while, it will be fine.

Hello, according to the situation you described, the motor of Octavia Automobile has a sizzling sound, he generally has two reasons, the first is that the motor shell and the car body have wires to tie the iron phenomenon, which will produce this sound, and the second is the sound produced by the friction between the shaft of the rotor and the carbon brush caused by the aging of the battery brush carbon brush in the motor, thank you, I hope it can help you.

Hello, this is the murmur of electricity, not only the Octavia, but also other Volkswagen cars. Mainly caused by interference. However, if it is serious, you can go to the store and test it.

The grinding sound of metal is mainly caused by the friction sound of the bearing damage caused by the sweep or the bearing sleeve and the casing.

2 .The vibration sound is due to the aging of the bearing, loose feet, unbalanced rotor, improper connection shaft, poor fit, cracking of the casing and so on.

3.Caused by humming, general overload, two items, short circuit between turns, etc.

4.Motors with wires wound rotors, open rotor circuits, grounding, low insulation, and also hum.

The Mingrui power-on motor has a sizzling sound all the time, which means that the first one may be leakage, and the second is that there may be bad lubrication inside.

This sound of the motor may be too high voltage, causing excessive current, and it may burn out.

Generally, when it is damp, there will be a little sound of ignition, and it is necessary to clean up the dust and keep it dry.

In this case, it is likely that the bearing piece is the fault, or it may be caused by uneven cutting of magnetic inductance lines, so it is important to pay attention to this aspect.

It should be discharging.

Or leakage.

It is recommended to go to the official after-sales inspection and maintenance.

The electric motor on the famous cabinet has been ringing, this may be because he has been running, so he will say, there is no need to worry about having always wanted to make one.

It is normal for the generator on the Skoda Octavia to have a sizzling sound, and the generator does work to generate electricity.

If you want to live, it may mean that there is a certain failure of his equipment, try not to use it, there may be problems.

It depends on the specific part of the sound that is coming from.

It is then judged based on performance.

It shows that Lin Rui's power-on motor has a sizzling sound, and it keeps ringing, what's going on? Turn the power off, turn it back on and try again.

What's actually going on? If it keeps ringing, it is possible that the sound card of the electric elevator is broken, and you can re-enter it.

If it is sizzling, it is generally a case of a short circuit in the current, and it is recommended that you check yours.

If the sound of the motor is loud all the time, it is very likely that there is a problem with the motor? You check it, is it that interference or leakage?

Summary. Hello. The causes of abnormal noise of the motor are: bearing failure, loose and falling off of the magnet, axial channeling, rotor sweeping, etc.

Hello. The causes of abnormal noise of the motor are: bearing failure, loose and falling off of the magnet, axial channeling, rotor sweeping, etc.

1. Bearing failure: If the bearing of the electric vehicle motor fails, it will cause the gap to become larger, the motor will not operate normally, and the abnormal sound will be caused. For this kind of problem, the general solution is to replace the new bearing, which can solve the problem of abnormal noise of the electric vehicle motor.

2. The magnet is loose and falls off: If the magnet inside the electric vehicle motor is loose and falls off, the performance of the motor will decline, and when the motor is running, it will make noise. For this kind of problem, the general solution is to re-bond the magnet, which can solve the problem of abnormal noise of the electric vehicle motor.

3. Axial channeling: If there is channeling in the internal axial direction of the electric vehicle motor, then when the motor is running, it will shake and make noise. For this kind of problem, the general solution is to add an appropriate amount of washer in the axial direction, so that the problem of abnormal noise of the motor can be solved to a certain extent.

4. Sweep the rotor: If the rotor of the motor and the stator are not concentrified, the local gap will become smaller, and friction will occur, causing the sweeping, which will bring the problem of abnormal noise from the motor. In this case, the general solution is to readjust the rotor and stator, and the problem can be solved.

Summary. According to your description, the biggest possibility is that your controller is not an ultra-quiet controller, and now electric vehicles generally use ultra-quiet controllers, and only a few manufacturers are still using ordinary controllers at a low price.

Another reason is that one of the power tubes of your controller MOS tube (power tube) is damaged, if you continue to use it, the damaged MOS tube will be completely broken down, and the phenomenon at that time is that it is difficult to push.

The last relatively small possible reason is that the Holer element in the motor has a large deviation of threshold consistency, and the signal transmitted to the controller is deviated, resulting in the controller not being able to supply power to the motor in a balanced manner, and the noise of the motor is significantly increased when the current is unbalanced.

The cause of the motor bearing is almost zero, because the mechanical failure is manifested by a regular and uninterrupted sound.

I hope it can help you, I wish you a happy life, and welcome to continue to consult next time.

So what should I do.

Do you have to fix it?

You can only go to a professional repair shop for repair, it is best to repair it after the manufacturer, if there is a problem, you can replace some parts of the original factory.

This must be a shout, you yourself must not have the ability to repair this game, after all, the main thing about electric vehicles is the motor, the motor fails, it must be repaired in time.

I hope it can help you, and welcome to continue to consult next time.

Summary. Another reason is that one of the power tubes (power tubes) of your electric vehicle controller is damaged, and if you continue to use it, the damaged MOS tubes will be completely broken down, and the phenomenon at that time is that it is difficult to push.

Hello, glad to answer for you, there are two cases of this.

One is that your electric vehicle controller is not an ultra-silent cover controller, and now electric vehicles generally use ultra-silent controllers, and only a few manufacturers are still using ordinary controllers at the low-end price of Bipei.

Another reason is that your electric vehicle controller MOS tube potato Qinglu (power tube) has a number of power tube damage, if you continue to use it, the damage will be completely broken down, and the phenomenon at that time is that it is difficult to push.

There is also a relatively small reason for the congruence deviation of the threshold value of the Hall element in the motor, and the signal transmitted to the controller is deviated, resulting in the pre-control hail bending device can not be balanced to supply power to the motor, and the noise of the motor will increase significantly when the current is unbalanced.

We hope you find this service helpful.

The friction sound of metal is mainly due to the friction sound of the bearing sleeve and the casing caused by bearing damage; The vibration sound is due to the aging of the bearing, loose feet, unbalanced rotor, improper connection shaft, poor fit, cracking of the casing and so on. Caused by humming, general overload, two items, short circuit between turns, etc.

If it is a variable frequency motor, the frequency may be too high, and the mechanical resonance point cannot be avoided. If there is no frequency converter, you should first determine whether it is a motor squeak or a mechanical squeak from the motor dragging. If the motor rotor shaft does not rotate and the motor makes abnormal noise, then it is certain that the rotor shaft and the rotor winding (cast aluminum rat dragon rotor) are loose.

To distinguish between electromagnetic noise, mechanical noise and ventilation noise, the step-by-step operation method is generally used to distinguish, that is, to disconnect a running part to analyze the noise source, for example, the noise generated by disconnecting the fan is electromagnetic noise or mechanical noise, and then cut off the power supply, and finally the noise can be judged as mechanical noise.
