got an issue with a high 1x on the NDE of a 185KW motor. This motor is used to drive a gearbox which turn rotates 5 rollers which push product through to create animal feed.
Running speed is 1485rpm, used hi-res spectrum to see if I could locate any sidebands but couldn't find anything obvious.
please see attached doc for more details
will post any progress to keep you all updated.
