Abstract: A stator apparatus includes a stator core and a wave-winding coil. The wave-winding coil includes a flexible conductor defining a first conductor portion and a second conductor portion between a first end and a second end. The first conductor portion is mechanically supported by a first stator slot cluster, a second stator slot cluster, and third stator slot cluster of a stator core such that a primary overhang extends from the first stator slot to the second stator slot and a secondary overhang extends from the second stator slot to the third stator slot. The second conductor portion is mechanically supported by the first stator slot cluster, second stator slot cluster, and third stator slot cluster such that primary and secondary overhangs of the second conductor portion extend over an opposite axial side of the stator core from the first conductor portion.
