How to deal with the malfunction of iron core motor in time and prolong its life?

The vibration of motor products in use must be dealt with in time, so that motor products can be better put into use later, so that the motor will not shorten the use time. Here is a short edition to introduce the relevant knowledge to users.

When the motor is running, the vibration of the motor is too large. The reason for this fault may be that the motor has abnormal vibration due to electromagnetic and mechanical reasons.

The power supply voltage of motor is asymmetrical, winding short circuit and individual branch circuit break in multi-winding, or the stator core is not tightly installed.

These electromagnetic reasons can cause vibration when the motor is running. The bending of the motor shaft, the elliptical diameter of the shaft or the unbalance of the rotating parts attached to the shaft, etc., may also cause the vibration of the motor when it is running.

Therefore, when the vibration of the motor is too large, the influence of the transmission parts on the motor can be checked first, and then the coupling can be detached to make the motor idle for inspection.

If the vibration of the motor is not large when idling, it may be due to the inaccurate alignment of the axis center of the motor and the driving mechanism, or the vibration between the motor and the driving mechanism may cause the vibration of the motor.

After determining the cause of the motor vibration, the user can check it again with the mechanical maintenance personnel and deal with the mechanical defects of the motor.
