e-NVH
Welcome to the "e-NVH Academy" of EOMYS!
In this section you will find online resources dealing with magnetic noise and vibrations in electric motors. e-NVH means "electromagnetically-excited Noise, Vibration and Harshness" or "electrical NVH" to refer to specific NVH issues taking place in electrical powertrains for automotive applications (EV/HEV NVH). A more general term for all applications is "electromagnetically-excited noise and vibrations".
The aim of these online resources is to provide educational materials for both electrical engineers and NVH test engineers to learn:
- the origin of electric motor whining noise and electromagnetically-excited vibrations
- the electromagnetic and structural design parameters that are the most influential on electric motor noise and vibrations
- the noise and vibration reduction techniques which can be applied at design stage or after manufacturing of electrical machines
These resources are parts of EOMYS detailed technical training on magnetic noise and vibrations in electrical machines and passive components. They include:
- articles and technical notes on NVH of electrical machines
- sound samples related to electromagnetic noise
- videos related to electrical machine noise & vibrations
- conference materials on e-NVH
- webinars on vibro-acoustics of electrical machines
To keep up with new e-NVH materials you can subscribe to our monthly newsletter.
