다단 단부를 가진 고정자를 가진 전기 기계

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 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 of the windings having the same linear length, each winding defining at least a first wrap and a second wrap wherein each of the first and second wraps circumscribes the stator core with each of the first and second wraps extending through one of the slots in each of the plurality of poles of one of the phases and wherein the first wrap of each winding is primarily disposed in a one of the layer positions and the second wrap of each winding is primarily disposed in a different one of the layer positions, the first wrap of each winding defining a first linear length and the second wrap of each winding defining a second linear length that differs from the first linear length, wherein the first and second linear lengths are equivalent to an unbent length of the corresponding wrap; andwherein the plurality of windings include a first winding and a second winding, the first winding defining the first wrap and the second wrap wherein the first wrap of the first winding is positioned radially outwardly of the second wrap of the first winding and the first linear length of the first wrap of the first winding is greater than the second linear length of the second wrap of the first winding, the second winding defining a first wrap having the same first linear length as the first wrap of the first winding and a second wrap having the same second linear length as the second wrap of the first winding, the first wrap of the first winding positioned radially outward of the first wrap of the second winding, the second wrap of the first winding being positioned radially inward of the first wrap of the second winding and radially outward of the second wrap of the second winding, wherein the first and second windings each define a plurality of end turns which extend axially beyond the stator core and define an axially extending end turn height, the end turn heights defined by the first and second wraps of the second winding being greater than the end turn heights of the first and second wraps of the first winding.
