چکیده :

This paper presents the design and optimization of a dual-stator, dual-rotor axial-flux switching permanent magnet (AFSPM) motor aimed at enhancing torque and efficiency for lightweight electric vehicle (EV) applications. A Taguchi-based optimization strategy is employed to systematically improve torque characteristics and overall performance. The proposed AFSPM motor features dual stators with 12 poles on each side and an internal 10-pole dual-rotor configuration. Phase-group concentrated windings are adopted to enhance fault-tolerant capability. The back electromotive force (EMF), cogging torque, average torque, torque ripple, and losses are analyzed using a three-dimensional finite element method (3D-FEM) to evaluate the AFSPM motor’s electromagnetic performance. A comparative study with existing AFSPM motor designs in the literature is conducted to validate the proposed structure’s superior torque density and efficiency. The optimized model demonstrates significant reductions in cogging torque and torque ripple, confirming that the proposed AFSPM motor is a promising candidate for efficient lightweight EV propulsion systems.
