Optimizing AFPMSM for Electric Vehicles: A Hybrid Stator Core Design for High Torque Density and Reduced Complexity
摘要
The use of axial flux permanent magnet synchronous machines (AFPMSM) in electric vehicles offers advantages in terms of torque-weight ratio, efficiency, and compactness. However, these machines face challenges related to design elements such as the configuration of permanent magnet arrangements, aspect ratio, rotor dimensions, and the choice of magnet materials, all of which impact performance. To address these issues and reduce manufacturing costs for electric vehicles, a hybrid AFPMSM has been proposed. The study employs Ansys Maxwell software to analyze the performance characteristics of this proposed motor. Key outcomes include insights into electromagnetic torque, torque density, and the impact of rotor geometry and pole arc ratio on torque generation. This research aims to enhance the viability of the proposed system for commercial EV applications by simplifying design complexities and leveraging advanced electromagnetic analysis tools. The results highlight improvements in performance characteristics crucial for upgrading axial flux permanent magnet machines, thus advancing their suitability for electric vehicle integration.
