Result
The graph shows the overall sound power level of the machine as a function of speed or time.
The red line indicates the speed above which the maximum spectrum frequency is above the frequency of study specified by the user with Input.Simu.freq_spec_max. The green line indicates the speed above which field weakening is applied if relevant.
For further plot options (e.g. change axis) see How to change plot options.
This graph allows to identify if any acoustic resonance occurs during the run-up of the electrical machine.
