Electric machine noise reduction with multi-physic modelling

Aachen Acoustics Colloquium – AAC, Aachen (Germany), November 2014

This paper describes the application of the multi-physics methodology developed by VibraTec for the NVH simulation of electric machines on two automotive cases in partnership with Valeo Electrical Systems, an ICE starter and a generator. The article will remind the principles of the simulation methodology and explains how it has been applied to the application cases for the virtual design and improvement of these systems.
