Sažetak
This study investigates the effect of the height-to-opening slot ratio on the stator yoke flux density in a Double Stator Single Rotor (DSSR) Axial Flux Permanent Magnet Brushless Direct Current (AFPM BLDC) motor. Unlike previous studies focusing primarily on topological or control-based improvements, this work emphasizes the geometric optimization of stator slots - a rarely analyzed yet critical aspect of AFPM motor design. A comprehensive parametric analysis covering 429 configurations was conducted using the finite element method (FEM) in the Ansys Maxwell environment. The relationships between slot geometry and flux behaviour were derived analytically and validated via simulation. The impact on efficiency, torque output, flux saturation, and torque ripple was systematically examined. This research provides practical guidelines for slot design in DSSR AFPM BLDC motors, contributing to higher electromagnetic performance and improved manufacturability.The DSSR AFPM BLDC motor operates under no-load conditions to assess the stator yoke flux density, stator tooth flux density, and rotor flux density. Finally, a multi-objective optimization approach using Genetic Algorithm(GA) is implemented to investigate the impact of different slot heights on magnetic performance, ensuring the optimal design is achieved by monitoring stator teeth, stator yoke and rotor yoke flux densities.
