ABSTRACT:
A stator for a multi-phase electric machine having a plurality of core segments interconnected with one another and a plurality of coils. At least one core segment includes a plurality of teeth and a back portion that at least partially interconnects the teeth. The back portion of each segment has a first arrangement in which the teeth of that segment are a first distance from one another and a second arrangement in which the teeth of that segment are a second distance from one another, the second distance being smaller than the first distance. Each coil surrounds at least a portion of one tooth, wherein all coils surrounding teeth of a single core segment interconnect to at least partially define one phase winding.
