Abstract :
This paper presents the design process of permanent magnets to enable a wide range of constant-power operation and reduce the torque ripple by using analytical and numerical methods in PMA-SynRM. For a wide range of constant-power operation, the minimum d-axis flux-linkage of the permanent magnet is designed to be close to zero. Moreover, the unbalanced flux density in each segment is adjusted by changing the size of each permanent magnet to reduce the torque ripple. Finally, control simulations and experiments will be conducted to prove the validity of the suggested process.
