Is excessive motor vibration related to bearings?

Some users in the process of product use encountered excessive vibration in the use of the motor how to go?

(1) Abnormal vibration of front end cover:

For the long-term operation of the motor, the bearing is easy to aging mechanical parts, when the bearing is worn, the end cover side of the motor is likely to produce obvious vibration to increase the scene, in addition, the motor shaft problems may also cause abnormal vibration when the love side, when the motor is used improperly, after long-term operation, may cause the motor shaft cracks. Or the bending deformation of the shaft leads to uneven force of the motor, and the vibration caused by such problems is often more obvious; When such problems occur, there is often a visible radial runout on the shaft side of the motor.

(2) Abnormal vibration of rear end cover:

Most motors are installed in the non-shaft side of the fan for heat dissipation, when the fan is damaged, there will be a significant increase in the rear end of the motor cover vibration phenomenon, such problems can be stopped to check the integrity of the fan, such as the fan is in good condition, you should check whether the motor rear bearing is abnormal.

(3) Abnormal vibration of frame:

As the main body of the motor, all kinds of vibration will be conveyed on the motor frame, when it is found that the motor as a whole has a more obvious vibration increase, it should first confirm whether the installation of the motor is loose, to ensure that each installation fastener is loose or deformed; When the external installation of the motor is tight and the various fasteners of the motor body are not loose, the disassembly inspection should be carried out to confirm whether the internal components of the motor are loose, and whether there are any conditions such as the loosening of the rotor eccentric block and the rotor sweeping.
