Individual motor test
Thread Content
When testing the motor (55KW) individually, the vibration levels were within the acceptable range when the foot bolts were loosened; however, after the foot bolts were tightened, the horizontal vibration level exceeded the specified limit by 6.2 mm/s. I checked and found that the motor has loose connections; even after adding copper sheets, the problem persists. Please help analyze this issue, experts. Thank you very much
Is this a new motor? I once experienced excessive vibration in a new motor; it turned out that one of the feet of the motor’s base was not level. I took it to have those feet ground flat, but my motor was quite large. It’s very likely that your small motor has soft feet

There might be weak areas in the foundation; use a vibration meter to measure the vibration of the foundation and identify the area where the vibration is greatest. It is possible to consider prefabricating a steel base again
Take a one-yuan coin and place it at several points on the base; then observe the direction of vibration as well as the areas where the vibration is most intense
Basically, it’s about ensuring that the foundation is level. 1 Use a level to check whether all surfaces of the foundation are level. 2 Place the motor on the foundation and use shims to fill any gaps between the motor’s feet and the foundation. 3 Check that the copper gaskets you installed are in place. Following these three steps should be sufficient
