Thanks for an insightful presentation. Would you be able to comment on below questions please : What is the spectrum indication because of loose stator core? What does 400 hz axial component of vibration in Hydro generator? Thanking you ahead.
Can you please explain what's the significance of 1x 2x 3x in VA? For example, The input shaft speed in a multi stage gearbox is always the same and what's the purpose of showing the frequency normalised and represented as multiples of shaft speed? Is 1x means first turn of the shaft and 2x means the second turn?? Thanks
Hello, I have data from some sensors placed on the large motor. In the spectrum of almost all sensors, I found large value of spectral power for only 0.1 Hz and sometimes 0.1Hz, 0.2 Hz and 0.3Hz. For higher frequency of more than 0.3 Hz spectral power is close to zero. Can you say me why for all spectrum I am getting higher value of spectral power for 0.1 Hz?

I saw ludeca but as soon as I heard the voice I was like ah that's my boi jason tranter!
How many shims can be placed at motor base for alignment

Great explanation!
Glad it was helpful!
i have only 1x with sidebands what that mean
It could be internal rubbing
Parabéns pelo vídeo.
can we detect electrical faults through this analysis......
yes we can
sub spanish pls :(
English only
