N2 - Recently, dual-permanent-magnet-excited (DPME) machine has been proposed for low-speed large-torque direct drive applications [1]. Unlike traditional PM machines, the DPME machine employs two sets of PMs, one on stator and the other on rotor. It relies on the field harmonics to achieve electromechanical energy conversion, and the so-called bi-directional field modulation effect (BFME) is artfully engaged to guarantee the effective coupling between the magnetic field excited by the armature windings and those excited by the two sets of PMs. It has been demonstrated that in coaxial magnetic gears the shape factors of the ferromagnetic segments have profound impacts on the field modulation effect, and the transmitted torque density [2]. Therefore, the purpose of this paper is to investigate the optimum design method for improving the BFME of DPME machine, so as to further improve the pull-out torque of this new type of machine.
