On September 26, Autocar Professional, in association with COMSOL, organised a technical webinar on the topic - Improving efficiency of an electric drivetrain by using Multiphysics – and Sharath BN, Technical Specialist, COMSOL, gave an in-depth overview about how the Multiphysics simulation suite helps engineers to conduct Multiphysics assessment of the various constituents of an EV drivetrain, by considering electromagnetics, vibrations, heat transfer, and solid mechanics.
The webinar delved into how COMSOL’s Multiphysics simulation tool can model an e-motor’s electro-mechanical parameters such as torque, and magnetostriction, and help in the calculation of losses as well as thermal analyses. The tool also allows assessment of demangnetisation and electromagnetic breakdown. Furthermore, engineers can also conduct various optimisation assessments such as parameter, shape, and topology optimisation.
BN explained that the COMSOL tool also has proof-of-concept (PoC) models such as 8-rotor, and 48-stator poles, in its simulation suite. The COMSOL Multiphysics suite also offers readymade CAD data, as well as offers dedicated features for motor modelling such as the magnet feature which can be used to ascertain magnetisation direction.
