Radial force spectrogram of a given spatial order (plot_VS_Fr_spectrogram_order)

Post-processing documentation
Matlab commandplot_VS_Fr_spectrogram_order
Module VS.pp
Description PLOT_VS_FR_SPECTOGRAM_ORDER draws the spectrogram of radial force harmonics for a particular order
Parameters r: wavenumber to plot (integer >=0)
Restrictions
See also plot_VS_Fr_spatiogram, plot_VS_Ft_spectrogram_order

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
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.
