Result

This MANATEE software post processing plots the calculated electromagnetically-excited radial vibration spectrogram of the electrical machine in terms of velocity. It gives the following graph on default simulation project:

Radial velocity spectrogram
Radial velocity spectrogram
plot_VS_Vr_spectrogram

Note that you can change some plot options of all default MANATEE post processings (e.g. axis limits, colormaps).

This graph help identifying the vibration resonances of variable speed electrical machines due to magnetic forces.
