Magnetic Field Modeling of Axial Flux Permanent Magnet Motor Using 3D Finite Element Method
Keywords:
Axial Flux Motor, Permanent Magnet, 3D Finite Element Method, Electric VehicleAbstract
This study examines the impact of permanent magnet placement on magnetic field distribution and torque characteristics in flux axial motors using a self-developed three-dimensional finite element method (3D-FEM) simulation tool. Two configurations were analyzed: interior permanent magnet synchronous motors (IPMSMs) and surface permanent magnet synchronous motors (SPMSMs). Results indicate that IPMSMs achieve a more uniform magnetic vector potential distribution and significantly higher average torque compared to SPMSMs. These insights support optimal design strategies for flux axial motors in electric vehicle applications, targeting enhanced performance and motor downsizing.
