1. A stator for an electric machine comprising:
a core including a plurality of slots; and
a multi-phase winding arrangement positioned on the core, each phase of the winding arrangement comprising a plurality of parallel paths defining a plurality of poles for the stator,
wherein each parallel path includes a plurality of coils positioned on the core, each coil defined by coil legs and end turns, the coil legs including left legs and right legs extending through the slots of the core, the left legs and right legs of each coil connected by first end turns at one end of the core and second end turns at an opposite end of the core,
wherein each pole is associated with a pole slot set comprised of multiple slots,
wherein each pole slot set includes a left slot, a middle slot, and a right slot, and
wherein, for each pole slot set, legs for each parallel path extend through one slot of said pole slot set such that conductors for all of the parallel paths of said phase of the winding arrangement are retained in each pole slot set, left legs of a first coil are in an outer half of the middle slot, and right legs of the first coil are in an inner half of a left slot of a right adjacent pole slot set.
