“Fantastic example of how destructive resonance problems can be on industrial assets. The customer had numerous issues and failures with a drive system, despite multiple motor changes and base modifications. The IRIS M Motion Amplification camera survey clearly showed a directional rocking motion of the motor at 1XRPM.
The base was severely flexing, causing weld cracking. Bump tests and transient coastdown with the AMS 2140 Analyser confirmed a resonance at 1465 CPM, close to the operating speed of 1489 RPM. As a temporary repair, adding 350Kg of mass to the motor lowered the natural frequency, reducing vibration levels from 25mm/sec to 8mm/sec, significantly reducing stress on the frame and machine until the base can be modified.” — Stuart Walker
