e-NVH root-cause analysis of electrical machines using MANATEE software (4/8)

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
