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; andthe plurality of windings mounted in the slots of the stator core with each phase of plurality of phases defining a plurality of poles circumferentially distributed about the stator core, each phase including at least three of the plurality of windings;wherein, for one of the phases, in a designated slot of a first pole, a first winding is disposed in a first layer position, a second winding is disposed in a second layer position, and a third winding is disposed in a third layer position, the first winding defining a first outside lead wire extending from the designated slot of the first pole;the second winding defining a second outside lead wire extending from a designated slot of a second pole wherein the second winding is disposed in the first layer position in the designated slot of the second pole and the third winding is disposed in the second layer position of the designated slot of the second pole and wherein the second winding includes an end loop extending from the first layer position in the designated slot of the second pole to the second layer position in the designated slot of the first pole; andthe third winding defining a third outside lead wire extending from a designated slot of a third pole wherein the third winding is disposed in the first layer position in the designated slot of the third pole and wherein the third winding includes a first end loop extending from the first layer position in the designated slot of the third pole to the second layer position of the designated slot in the second pole and a second end loop extending from the second layer position of the designated slot in the second pole to the third layer position of the designated slot in the first pole with the first and second end loops being on opposite axial ends of the stator core; andwherein the first pole, the second pole, and the third pole form circumferentially sequential poles of the one phase with the second pole being disposed between the first and third pole and wherein the first layer position is a radially outermost layer position, the second layer position is disposed radially inward of the first layer position, and the third layer position is disposed radially inward of the second layer position.
