Robust e-NVH design of electrical machines using MANATEE software (5/8)

e-NVH e-NVH technical webinar 5/8
Objective Robust e-NVH design of electrical machines using MANATEE software
Date 19th May 2020
Hour 9:30 GMT and 16:00 GMT

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

Theorical part

- general impact of magnetic and geometrical asymmetries on magnetic forces and resulting noise and vibrations
- particular case of static & dynamic eccentricities
- particular case of uneven airgap & uneven magnetization
- uncertainties of the e-NVH design process: temperature effects, strong coupling due to UMP
- e-NVH effect of faults (short circuit, broken bar, demagnetized magnet)

Application with MANATEE software

- dispersion of natural frequencies
- sensitivity study on eccentricity level
- simulation of unbalanced currents, pole displacement
