With the expansion of industries an‎d the increasing application of electrical machines, particularly axial flux permanent magnet (machines, improving the performance of these machines has gained significant importance. One of the recently introduced novel structures is the axial flux machine with a ring winding configuration. While this structure offers several advantages, it also faces certain challenges, among which high torque ripple is prominent, leading to mechanical vibrations an‎d acoustic noise. In this study, the effects of several torque ripple reduction methods—such as magnet skewing, pole grouping, Halbach arrays, an‎d the use of soft magnetic composite materials—on the performance of this type of machine have been investigated. Initially, rotor an‎d stator modifications were eva‎luated separately. Subsequently, by employing a genetic algorithm an‎d combining rotor an‎d stator design changes, an improved machine model was proposed. The machine’s performance under motoring conditions was obtained through three-dimensional finite element modeling in Ansys Maxwell an‎d validated against experimental results.
