In particular, it will be achieved through 2 main steps: | ||
* eFrequencies determination and displays: They represent the characteristic frequencies that one may expect to find in the spectra. They are based on the specificities of the motor and depend on the RPM. For this reason, they are defined as harmonics. | * eFrequencies determination and displays: They represent the characteristic frequencies that one may expect to find in the spectra.

Determining the spatiogram responsible for the vibration harmonic that should be decreased is one of the major objectives of the EVHV module. | ||
