Hi,


I modeled a motor with broken rotor bars and following is the frequency spectrum of current data.



here f=supply frequency and s=slip of the motor


The appearance of sidebands around the supply frequency are fine.


Here it can be seen that amplitude of (1-2s)f < (1+2s)f


However, in literature, it has been said that amplitude of (1-2s)f > (1+2s)f.


Why is that Maxwell showing opposite results?


Can anyone please comment on this!
