چکیده :

Switched reluctance motors (SRMs) have attracted notable attention in electric drive applications owing to their simple design and high reliability. However, their broader adoption is constrained by the intrinsic torque ripple, which negatively impacts operational performance. This study presents a new axial-flux dual-stator SRM featuring a fourphase 8/14 pole configuration, specifically designed to reduce torque pulsations while enhancing average torque across variable-speed ranges. Compared with traditional radial-flux SRMs utilizing 8/6 pole structures, the axial-flux topology takes advantage of an increased rotor pole count to achieve superior performance. An analytical design framework is applied to refine the SRM’s electromagnetic behavior, with a focus on mitigating torque ripple and improving average torque. Validation of the proposed model is conducted through a detailed 3D finite element analysis (FEA) in ANSYS Maxwell. The comparative simulations demonstrate that adopting an axial-flux architecture with a larger number of rotor poles significantly decreases torque ripple and markedly improves the average torque output.
