Abstract

The increasing adoption of Electric Vehicles (EVs) drives innovation in efficient and highpower-density traction motors, such as the Yokeless and Segmented Armature Axial Flux Permanent Magnet (YASA AFPM) motor. Despite its advantages in lightweight construction and high torque density, the YASA AFPM suffers from cogging torque, which causes vibrations and noise, particularly at low speeds. This study aims to minimize cogging torque in YASA AFPM by optimizing the magnet and stator geometry without significantly compromising motor performance. The methodology integrates 3D Finite Element Analysis (FEA) simulation with Response Surface Methodology (RSM) for mathematical modeling and Genetic Algorithm (GA) for the optimization process. The varied design parameters include inner (α) and outer (β) magnet shifting angles, air gap length (g), and stator slot opening (b0). This optimal design successfully reduced the cogging torque significantly from 0.6215 Nm in the baseline model to 0.1168 Nm, equivalent to a reduction of 81.31%. Although there is a slight decrease in efficiency from 93.4% to 92.9% due to the air gap widening, the overall motor performance is considered excellent with a much smoother torque profile, making this design more suitable for electric vehicle applications.
