my case is an atlas copco compressor GA132w-10 fitted with 3000 RPm Motor ABB
number of male element and female element is not known but i suspect something will show you in the spectrum
the sharp frequency is 6XTS i think its related to blade pass frequency the the time diffrence between the impacts in the waveform =0.003418 second
so related to frequency =(1/0.003418)hz=17554.12 cpm if we check which order is this frequency we found that 17554.12/3000 = about 6XTS which related to vane frequency the family of compressors all have this frequency but this is the highest value. any ideas dears.
