| Abstract |
This study analyzes the electomagnetic performances of a yokeless and segmented armature-type axial flux motor under no-load conditions, incorporating a Halbach magnet array and various skew structures. Halbach magnet array and skew structures exhibit trade-offs among cogging torque, total harmonic distortion of back-electromotive force, and average torque, necessitating an evaluation of their combined effects on design parameters. Finite element analysis was employed to investigate the no-load electromagnetic performance with respect to two key design parameters. The results confirm that different skew structures have distinct impacts on electromagnetic performances according to the key parameters. |
