Dr. Nirmal Paudel delivered a keynote talk on “Electromagnetic Simulation of an Axial Flux Motor” at COMSOL Day: Vehicle Electrification. Designing electric vehicle (EV) powertrains and motors is challenging, given the competing requirements for energy efficiency, compactness, weight, thermal control, and other concerns. One enabling technology ideally suited to EVs is the axial flux motor (AFM). AFMs are electric motors where magnetic flux flows axially through the rotor, allowing a more compact and lightweight design than traditional radial flux machines, as well as high-power density and efficient cooling.
In this webinar, Dr. Paudel explored how to simulate an axial flux motor using COMSOL Multiphysics. He covered the steps required to compute torque, to calculate various losses (such as copper, iron, and stray losses), and to determine efficiency to understand the overall performance of the machine. He worked through an EV AFM example in detail to illustrate how these calculations, including static and transient simulations, can provide practical design and optimization insights.
