Axial flux machines have positive sides on the power and torque density profile. However,\nthe price of this profile is paid by the torque ripples and irregular magnetic flux density production.\nTo gather higher efficiency, torque ripples should close to the zero and the stator side iron should be\nunsaturated. Torque ripples mainly occur due to the interaction between the rotor poles and the stator\nteeth. In this study, different rotor poles are investigated in contrast to stator magnetic flux density\nand the torque ripple effects. Since the components of the axial flux machines vary by the radius,\nanalysis of the magnetic resources is more complicated. Thus, 3D-FEA (finite element analysis) is\nused to simulate the effects. The infrastructure of the characteristics which are obtained from the\n3D-FEA analysis is built by the magnetic equivalent circuit (MAGEC) analysis to understand the\nrelationships of the parameters. The principal goal of this research is a smoother distribution of the\nmagnetic flux density and lower torque ripples. As the result, the implementations on the rotor poles\nhave interesting influences on the torque ripple and flux density profiles. The MAGEC and 3D-FEA\nresults validate each other. The torque ripple is reduced and the magnetic flux density is softened on\nAFPM irons. In conclusion, the proposed rotors have good impacts on the motor performance.
