...Most of the more recent research in this field has been devoted to motors with nonoverlapping windings, either with SPMs [4], [5] or IPMs [6], [7], although such IPM machines are often very similar to SPM ones for magnet layout and for having rather a low saliency....

...As well known, in fractional-slot SPM machine, there are many air-gap field harmonics mainly caused by the slot effect [23] and nonsinusoidal armature MMF distribution determined by nonoverlapping concentrated winding layout [24]–[26], resulting in severe parasitic effect, such as eddy-current loss and torque ripple [27]–[30]....
