Result
This MANATEE software post processing draws the spectrogram of magnetic radial force harmonics of specified wavenumber r.
As an example, the radial force spectrogram of wavenumber r=2 is given in default MANATEE project by:
- Radial force spectrogram of spatial order +/- 2
- plot_VS_Fr_spetrogram_order
One can identify a strong rotating harmonic force travelling in backward direction (negative frequency).
Note that you can change some plot options of all default MANATEE post processings (e.g. axis limits, colormaps).
This graph can be used to confirm our understanding of the origin of electromagnetic noise and vibration in electric motors.
