Electric excitations can be easily characterized (PWM, slotting…) thanks to the e-markers that highlight directly the right frequencies. On top of that, the spatiogram is a unique tool to quickly quantify the electromagnetic excitation distribution responsible of the vibrations. Finally, sound design allows to playback and listen the motor noise separating and designing the various sources (aerodynamical, mechanical and eletromagnetic).
