Some users may encounter the problem of abnormal vibration and noise of the servo motor. If there is vibration and noise of the servo motor, the vibration and noise must be distinguished first. Generally under normal operating conditions, 1 kHz is the difference between vibration and noise - if the measured frequency is 1 kHz or lower, the problem is vibration, and any frequency above that should be considered noise. This situation not only affects production efficiency, but may also cause damage to the machine. This article will briefly analyze the reasons for the abnormal noise of the servo motor and provide solutions for reference.

The cause of the abnormal noise of the servo motor

1. Mechanical structure problems

There may be problems with the mechanical structure of the servo motor, such as poor lubrication of the bearings of the motor, resulting in wear of the bearings, loose bearings, loose internal parts of the motor, and debris inside the motor. These problems can cause abnormal noise when the motor is running.

2. Drive problem

The driver of the servo motor may have problems such as incorrect parameter setting and unstable power supply voltage. These problems will cause the driver to work unstable, generate vibration and abnormal noise.

3. Motor control issues

There may be problems in the control system of the servo motor, such as controller failure, control signal interference, etc. These problems can lead to unstable motor control and abnormal noise.

Solution to Abnormal Noise of Servo Motor

1. Check the mechanical structure

If there is abnormal noise in the servo motor, first check whether there is a problem with the mechanical structure. Check whether the bearings are worn or loose; check whether the internal parts of the motor are loose. Replace or repair if necessary.

2. Check the drive

If there is no problem with the mechanical structure, you can check the drive. Check whether the parameter settings are correct and whether the power supply voltage is stable; it is necessary to reset the parameters or replace the power supply.

3. Check the control system

If there is no problem with the mechanical structure and the driver, you can check the control system again. Check whether the controller fails, check whether the control signal is disturbed. It is necessary to replace the controller or install an interference filter.

In short, the abnormal noise of servo motor vibration is a common problem, and measures need to be taken in time. By checking the mechanical structure, drive and control system, the cause of the problem can be found and corresponding solutions can be taken. This can ensure the stability and precision of the servo motor, improve production efficiency and reduce the risk of machine damage.
