Experimental characterization of magnetic noise and vibrations

This technical bibliography comes from EOMYS technical training on the experimental characterization of magnetic noise and vibrations in electric drives. It is regularly updated based on EOMYS consulting experience in the assessment and control of e-NVH in electrical machines and drives.

Troubleshooting noise and vibration issues in electric drives requires a specialized experimental NVH test campaign with special post processing. The interpretations of measured spectrograms can also help identifying all gaps between reality and simulation (e.g. mechanical / magnetic asymmetries, tolerances). Testing is necessary to build a reliable 3D FEA mechanical model of the electric drive. Once a realistic 3D FEA model is built after fitting the CAE methodology with experiments, it can be used during the e-NVH virtual prototyping process using Manatee software.
