TL;DR: In this paper, a dual-stator spoke array (DSSA) VPM topology was proposed to achieve high power factor and high torque capability, and the performance of the DSSA VPM was evaluated based on finite element analysis, including power factor, torque density and cogging torque.

TL;DR: In this paper, a general instantaneous torque equation of VPM machines is proposed to analyze torque features and the effect of parameters on the torque performance of a VPM machine, and based on the general torque equation and a finite-element algorithm, it is verified that torque smoothness is the inherent characteristic of VTM machines, and the torque ripple of VMTs can be below 0.2%.

TL;DR: In this paper, the authors proposed a consequent-pole FRPM machine whose magnet usage is halved compared with that of a conventional FRPM, which exhibits larger back EMF and torque than that of the conventional one.

TL;DR: In this article, an advanced PMV machine topology with multiple working harmonics is proposed, which achieves ∼20% higher torque density than that of a regular nonoverlapping winding PMV with the same magnet usage.

TL;DR: In this paper, a flux switching permanent magnet (FSPM) was analyzed based on the star-of-slots (SOS) theory and a new type winding configuration with overlapping windings was predicted and verified to be with ∼90% larger back EMF than those of conventional FSPM machines with nonoverlapping windings.
