e-NVH prediction of switching effects in PWM-driven electrical machines using MANATEE software (6/8)

e-NVH e-NVH technical webinar 6/8
Objective e-NVH prediction of switching effects in PWM-driven electrical machines using MANATEE software
Date 26th 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

- PWM principle and commutation strategies
- PWM force harmonics and switching noise due to power electronics
- Sound quality considerations

Spectrum of PWM electromagnetic excitations
Application with MANATEE software

- PWM modeling strategies: analytic, numerical, Simulink, import
- Transient and steady state simulation
- Sound quality metrics
- Application to a electric motor variable speed vibroacoustic simulation
