The relationship between motors and vibration
Thread Content
These past few days, there has been a vertical centrifugal pump on site; during operation, the motor burned out. We contacted the electrical team for an inspection, and they said that excessive vibration of the pump was the cause of the motor’s burnout. Now they want us to resolve the vibration issue. I would like to ask everyone: the motor burns out due to high current and high temperatures. So why does excessive vibration cause the motor to burn out? \ud83d\ude0a
Generally, if a motor burns out due to excessive pump vibration, it is because the vibration of the pump causes increased vibration in the motor, which ultimately leads to damage to the motor bearings and results in the motor rotor colliding with the stator and getting damaged
The pump experiences high vibration and heavy load, causing the motor to burn out.
Is there a barrel cleaner? Have you put on the running jacket? Are there any signs of wear on the stator?
