How to better handling thermal challenges in e-motors

PRESENTER:
Elia Cipolato & Didier Zefack

EXPERTISE:
Electromagnetics

Software:
JMAG

In recent years, the use of motors has been increasing in many industries due to environmental concerns. Especially in automotive industry, as the shift to electric vehicles (EVs) accelerates globally, the demands of developing motors has requested them to be smaller, more efficient, and safer.
One of the most important CAE efforts in motor development is to solve thermal challenges. This requires simulating temperature distribution using the 3D model with complex geometry and consider the most suitable cooling method for it. Cradle CFD, the thermal fluid analysis software in Hexagon solution, achieves it by collaborating with JMAG, the electromagnetic field analysis software.
Cradle CFD allows to import the Joule losses simulated by JMAG as heat condition, predicts heat transfer near the surfaces and simulates temperature distribution with the complex model of motor created by its powerful meshing. In this presentation, we introduce the workflow and the benefits of using Cradle CFD and JMAG.
