Audi is one of the most iconic representatives of the premium electric vehicle on the market. For their flagship vehicle, the Audi e-Tron, they made the less common choice to use a squirrel cage induction machine. Thus, the paper presents a 2D finite element model of the AUDI e-Tron electric motor series and reviews its performances and design choices. The numerical model is created using Altair FluxMotorTM software after having gathered the main data on this machine. After validating the model by comparing simulation results with theoretical performances, the voltage-frequency control curve is established, aside with the highest efficiency working points. Although this 2D model is still perfectible, it is well representative of the performance of the real motor and useful for further simulations.
 

Presented at

This article is presented at International Conference ?????????. Its title is "Modelling and design analysis of the Tesla Model S induction motor". The authors are Hugo HUSSON, Robin THOMAS, Lauric GARBUIO from G2Elab's research teams.
This paper will be available very soon on HAL.

Downloadable model description

The downloadable model is the Audi e-Tron 2D finite element electromagnetic model made with Altair Flux2DTM software and presented in the article. It includes the geometry, the materials characteristics and the implemented equivalent electrical diagram in the case where the motor is fed by three voltage sources. This model can be used for pedagogical purposes or to carry out retro-engineering studies on the design or operation of the machine.
