e-NVH	e-NVH technical webinar 4/8
Objective	e-NVH root-cause analysis of electrical machines using MANATEE software
Date	5th May 2020
Hour	9:30 CET and 16:00 CET

Organization

The webinar includes:
A theoretical part of 30 mn on e-NVH
An application with MANATEE software over 20 mn
An open question part over 10 mn

Description

Theoretical part

Forced excitation and resonance, notion of modal force
Air-borne and structure-borne noise
Transfer paths of magnetic noise and vibrations
Sources of electromagnetic excitation harmonics (winding, slotting, switching)

Application with MANATEE software

Root cause analysis methodology
Order Tracking analysis, spatiograms
Magnetic load case contribution (e.g. UMP, torque ripple) and modal contribution
Automated harmonic analysis, used-defined harmonic filters and offline harmonic analysis
