Multiphysics E-Motor Design Process Through Optimisation

Multiphysics Community Event


The electrification of functions in transportation is bringing new challenges to the design of electric machines. Often high-speed for compactness and controlled by PWM techniques, electric machines have to minimize energy consumptions over driving cycles, are facing high mechanical stresses in rotors and have to be cooled to sustain high power densities. To face these challenges, new technologies and topologies have to be found.

Simulation and optimization tools are evolving to help provide innovative solutions. Electromagnetic simulation is at the heart of the modelling process, but other constraints such as thermal effects, vibrations, structural stress, acoustics, and overall system requirements must also be taken into account.

As time-to-market is a key for success, the tools have to offer a streamlined optimization process, allowing the design space to be searched widely and efficiently, helping motor designers to meet all kinds of multiphysics constraints.

In this webinar, such a process will be presented, coupling various solvers (electromagnetic, mechanical, thermal) leading to an optimized design from a multiphysics perspective.

About this event

The Multiphysics Community allows members to engage with experts on the NAFEMS Multiphysics Working Group. No significant knowledge or expertise is required to participate. The only requirement is a desire to learn more and interact with other engineers and scientists who have an interest in Multiphysics analysis and simulation. More information can be found on the Multiphysics Community webpage.
