We are analyzing some 24,000 - 30,000 rpm motorized spindles equipped with ceramic bearings that are classed at ABEC9. I don't have specific bearing numbers, don't know the DN#, or the specific type of lube being used (yet).
The vibration data for the first few units we have looked at has what...

I'm looking for any feedback from users of capacitive proximity probes (e.g. Vibrosystm 'PCS' models) regarding their claimed insensitivity to electrical runout & surface magnetism variations. Has anyone done any direct comparisons of eddy current (Bently) vs. capacitive transducers to determine...
I've got a unique situation with a recently re-stacked hydrogenerator. Vitals are:
# poles = 56 ; # stator slots = 360 ; line freq = 60 Hz ; rpm = 128.57
Old design had 4 stator core splits ; New design uses a continuous core stack
Vibration taken directly from the back of the...
