Sidebands with CSI Peakvue
Sidebands with CSI Peakvue
(OP)
I have noticed sidebanding around turning speed and it's harmonics with peakvue. On 1800 rpm equipment the sidebanding is around 3Hz. On 3600 rpm equipment the sidebanding is around 5 Hz. I see this on motors, pumps, fans etc. It is not cage or slip pole. Any suggestions would be appreciated? I believe it is caused from bearing looseness but can not pin point the cause of the low frequency sidebands. Any ideas?

Since you see it on many pieces of equipment makes it even more puzzling. The more reproduceable it is among machines might steer toward something to do with the setup filters?
