What is it about?
As electric vehicles become more popular, there's a growing need for motors that can handle high temperatures without losing performance or breaking down. This study focuses on a specific type of motor called an "axial flux permanent magnet" motor, which is compact and powerful but requires effective cooling. By using advanced computer modeling, we explore how heat moves through the motor and test ways to improve cooling. Our goal is to make electric vehicle motors more efficient, reliable, and longer-lasting.

Why is it important?
This study stands out by offering a dual-model approach to better understand and manage heat in electric vehicle motors. We used two types of models: a detailed 3D computer model (finite element analysis) and a faster, simpler model (lumped parameter thermal network) that can still accurately predict motor temperatures. This combined approach provides both depth and speed in analyzing motor heat, making it feasible to predict and improve motor performance under different conditions. The findings could lead to more durable, efficient motors that meet the demands of high-performance electric vehicles.
