Result

The following sound power level spectrum is obtained on an induction with high slip:

A-weighted sound power level sepctrum
A-weighted sound power level sepctrum
plot_ASWL_fft

One can see that due to leakage the spectrum is not discrete. To reduce spectral leakage one can increase the number of revolution as shown in ALG_005 validation case or active the frequency solver of MANATEE.
