Hello guys,
I got a small 12V DC brushed motor and collected its current data. After performing the FFT of the signal, I found there are multiple orders present many of which I didn't expect. as motor has 12 commutators I saw a 12th order and maybe due to shakiness of brushes I saw some 24th order too. Also, there was a 5th order, which my colleague suggested is due to the sin winding on motor. but there are other orders like 7, 19, 36, etc
It would be great if someone can explain the presence of these orders
Thanks :grin:
