Vibration Analysis Case Study 1 - Electrical Vibration Problem

In this first case study from his book "Enhancing System Reliability Through Vibration Technology", James Sylvester from JPS Reliability and an Reliability Training Institute Trainer, shows how vibration analysis can be used to diagnose electrical vibration problems. In this case a VFD driven Motor. Over the next few weeks James is going to share a selection of interesting vibration analysis case studies.

Hi James, i accidentally clicked the cross on linked in with you wanted to connect, massive apologies on my part. Could you send it again?

[@mahdijalali8518]

excuse me sir if machine has VFD, side bands are 100 hz again or are depend on feed currency?

[@MotionAmplificationRMSLtd]

Yes Mahdi, you would get different frequencys in spectrum depending on VFD drive input

[@mahdijalali8518]

@@MotionAmplificationRMSLtd thank you,,

[@daddyo5054]

yeah... this can be bad! In USA 🇺🇸 it would be 120 Hz (2×Fl) with approximately 20Hz side bands. had one get up around .8 in/sec (20+ mm/sec)
