How to solve the problem of large motor vibration

Motor jitter refers to vibration or jitter when the motor is running. It is mainly caused by factors such as motor imbalance, mechanical system instability, design error or component failure. If not solved in time, motor jitter will not only reduce the working efficiency and life of the equipment, but also may cause serious accidents.

In order to solve the problem of motor jitter, this article will discuss the following aspects.

1. Positioning problem

First of all, it is necessary to clarify the specific cause of motor jitter. There are many reasons for motor jitter, such as damage to motor bearings, misalignment of motor blades, poor matching of rotor and stator, etc., so the fault must be checked and located.

When troubleshooting, the specific location of the fault can be determined by checking indicators such as motor noise, vibration and odor. At the same time, instruments such as infrared thermometers can be used to detect the temperature and installation position of the motor to locate the fault more accurately.

2. Strengthen maintenance

In order to avoid the problem of motor jitter, the maintenance of the equipment must be strengthened. Specifically, the motor should be inspected and maintained regularly, including cleaning the motor surface, adding lubricating oil, adjusting the motor matching, etc.

In addition, the motor should be maintained on a daily basis, such as regularly checking the motor cable connection, checking the wear of the motor blades and bearings, and checking the fit of the stator and rotor.

3. Perform motor balance check

The imbalance of the motor is one of the main reasons for the large motor vibration. Therefore, when installing the motor, a balance check must be performed to ensure that the motor is balanced.

Motor balance check is an important quality control method that can detect the balance state of the motor and adjust it to minimize the vibration and noise of the motor. During the motor balance check, a precise balance check instrument is required to detect the imbalance of the motor and take corresponding measures to correct it.

4. Adjust the motor fit

Poor motor fit is also one of the common problems that cause large motor vibration. In response to this situation, adjustments can be made in the following ways:

First, when installing the motor, the motor and auxiliary equipment need to be accurately installed to ensure good fit between the motor and the equipment.

Secondly, when checking the motor, it is necessary to pay attention to the fit of the motor blades, bearings, stators and rotors. If poor fit is found, it should be adjusted in time.

In addition, when performing motor maintenance, you can also clean and lubricate the motor's matching parts to ensure good matching of the motor.

5. Replace faulty parts

If the reason for the large motor jitter is due to faulty parts, then you need to consider replacing the faulty parts. Common faulty parts include motor bearings, blades, rotating shafts, etc.

When replacing faulty parts, you need to first determine the specific location and type of the faulty parts, and then select the correct parts for replacement.

In addition, after replacing the faulty parts, you also need to perform balance checks and matching adjustments on the motor to ensure that the motor works stably.

Summary

Large motor jitter is a common fault that will have a serious impact on the stability, work efficiency and service life of the equipment in production. To solve the problem of large motor jitter, first you need to understand the cause of the fault, then locate and troubleshoot it.

Then strengthen the maintenance and maintenance of the equipment, regularly check the connection and component conditions of the motor, and clean and lubricate it in time.

In addition, the problem of large motor jitter can also be solved by motor balance checks and matching adjustments. Finally, it is necessary to pay attention to balance checks and matching adjustments after replacing faulty parts to ensure that the motor can work normally.
