    The Effects of Rotor Delta and Embrace Parameters on the Performance of Flux-Switching Generator; [Rotor Kutup Eǧimi ve Yay-Kutup Adimi Orani Parametrelerinin Aki-Anahtarlamali Generatörün Başarimina Etkileri]

    One of the types of generators used in variable-speed wind turbine applications in microgrids is the flux-switching generator. Due to the double-salient structure of flux-switching generators, torque ripples and harmonic content are high. In addition, the magnetic flux density in the stator and rotor teeth is elevated. To overcome these issues, improvements can be made in the machine's design parameters. In this study, the effects of rotor pole skew (delta) and coil-pole pitch ratio (embrace) parameters on the machine-s output values for a 1200 min-1, 200 Hz, and 260W design were examined. It was observed that changes in the pole skew and coil-pole pitch ratio parameters affect torque, flux linkage, and induced voltage values, and can reduce magnetic stresses © 2024 IEEE.

    The Effects of the Multi-Slice Skewing Applied to the Rotor on the Performance of a Flux Switching Generator; [Aki Anahtarlamali Generatörde Rotora Uygulanan Çok Katmanli Kaykinin Makina Başarimina Etkileri]
    (Institute of Electrical and Electronics Engineers Inc., 2024) Durmaz S.T.; Isikelekoglu T.; Ozmen T.; Ergun B.E.; Onat N.; Gulbahce M.O.
    Flux-switching generators are one of the types of generators commonly used in wind turbine applications, particularly in microgrids. The torque ripple and harmonic content of flux-switching generators are significantly high due to the salient pole structure of the stator and rotor teeth. In this study, a multi-layer skewing method was applied to the rotor of a 260 W flux-switching generator, and its effects on the generator's average torque, torque ripple, and efficiency parameters were analyzed. The obtained results indicated that, due to the dominance of the second harmonic, the skewing angle did not have a significant effect on the output parameters. Furthermore, the influence of the number of layers on the generator's output parameters and production difficulty was examined. © 2024 IEEE.
