Simulation of Effects of Mechanical Deformations to Electromagnetic Performance and Mechanical Forces in an EV Traction Motor

Bilquis Mohamodhosen, Solution Consultant, Dassault Systemes

Integration of electric motors for traction in electric vehicles (EVs) has shown that consideration of the mechanical effects from the drive train on the electromagnetic performance is vital at the design stage. The authors examine the performance sensitivity of an 8-pole, 55 kW IPM traction machine to deformations such as stator ovalling, tooth rocking and rotor tilt using the SIMULIA Opera finite element software. In particular, techniques evolved to minimize errors resulting from use of numerical simulation are discussed and results required for multiphysics simulation when Opera is integrated with multi-body mechanical simulation software are presented.

Bilquis Mohamodhosen  is a Solution Consultant at SIMULIA Electromagnetics Group since April 2019. She is specialized in electrical machines, and provides support to customers in this field to set up and analyze their models. She is part of the Application team within SIMULIA Opera, which aims at a more elaborate and in-depth testing and usage of the software, and has interests in multi-physics simulation and optimization. She graduated with a PhD in topology optimization of electrical machines from Ecole Centrale de Lille (France) in 2017. She has also worked as a post-doctoral researcher in noise and vibration analysis in electrical machines at the same institution before joining Dassault Systèmes.
