Result

The flux density distribution is the main output of the electromagnetic model of MANATEE software as it is used to calculate the Maxwell stress tensor responsible for electromagnetically-excited audible noise.

This particular post processing plots the tangential airgap flux as a function of airgap angle, including the corresponding Fourier analysis:

Note that this 1D FFT graph gives only a partial view of the harmonics, as both space and time frequencies are involved in noise and vibration generation. A 2D Fourier transform of the flux is available with plot_Bt_cfft2.

To change the default plot options you can read How to change post processing plot options ? article.

This graph help identifying the space harmonics involved in flux density which may affect the noise and vibration behaviour of the electrical machine.
