5. Experimental characterization and diagnosis of magnetic noise

Although the methods presented in section 3 can be used to estimate the vibroacoustic behavior of electrical machines, experimental verification is always necessary to recalibrate models (especially modal damping coefficients). Vibroacoustic testing allows us to characterize the nature of the magnetic excitation (amplitude, frequency, origin of harmonics), the nature of the...
