1. A multi-phase electric machine comprising: a stator operably coupled with a rotor wherein the rotor is rotatable relative to the stator, the stator including a stator core and a plurality of windings defining a plurality of phases;the stator core defining a plurality of axially and radially extending slots which circumscribe the stator core and encircle a rotational axis of the electric machine, each of the slots defining a plurality of layer positions located at different radial distances from the rotational axis;the plurality of windings being mounted in the slots of the stator core with each phase of the plurality of phases defining a plurality of poles circumferentially distributed about the stator core, each of the phases being defined by a portion of the plurality of windings, wherein each winding defines a plurality of wraps wherein each of the wraps circumscribes the stator core with the winding extending through one of the slots in each of the plurality of poles of one of the phases;wherein each winding defines a plurality of end turns which extend axially beyond the stator core wherein each of the plurality of end turns defines an axially extending end turn height;wherein the plurality of layer positions form a plurality of layer position groups, each of the layer position groups being formed by a plurality of radially adjacent layer positions;wherein the plurality of wraps defined by each winding includes at least one wrap disposed in each respective one of the plurality of layer position groups;wherein for each respective layer position group, the windings disposed in the plurality of radially adjacent layer positions define an end turn height which becomes progressively taller in a radially inward direction; andwherein the end turn height of the winding disposed in a radially outermost layer position of each of the layer position groups is less than the end turn height of the winding disposed in a radially innermost layer position of each of the layer position groups.
