要約(英語): Undesirable torque ripples in permanent magnet synchronous motors occur because of the spatial harmonics of the inductance and permanent magnet fluxes. Previous studies have proposed several methods for suppressing these torque ripples based on mathematical models. However, most of them do not consider the magnetic saturation. Hence, the torque ripple estimation accuracy may deteriorate, and the torque ripple suppression performance is reduced in the magnetic saturation range. Therefore, this paper proposes a torque ripple suppression method by considering the magnetic saturation based on the estimated harmonic component of the flux linkage and clarification of its effectiveness through simulations and experiments. From the experimental results, the proposed method is seen to suppress the 6th-order torque ripple by 69.1%, which is higher than that of the conventional method. Therefore, it is verified that the proposed method can suppress torque ripples, including those in the magnetic saturation range.
