motor load from current FFT analysis
motor load from current FFT analysis
(OP)
I did a few searches for current analysis and came up empty.
We have several 100 HP agitators that have broken teeth in their 12-1 double reduction gearboxes. There is vibration very apparent all over the place at blade pass ( around 284 cpm ).
Would you expect basic current analysis with a clamp on probe, resistor, and IRD/CSI etc data collector on the 460 v, 121 FLA induction motors to reflect "instantaneous" load variations, for instance at Blade pass frequency?
thanks
