9. A method of fabricating a rotor for an electrical machine, the method comprising the steps of:
-
fabricating a first slot and a second slot proximate to an edge of a rotor, the first and second slots at least partially closed by the edge of the rotor; inserting a first end of a first hairpin winding into a first end of the first slot; inserting a second end of the first hairpin winding into a first end of the second slot, the first end of the first slot and the first end of the second slot disposed at an end of the rotor; and advancing the first and second ends of the first hairpin winding in a same direction through the first and second slots, respectively, such that the first and second ends of the first hairpin winding exit the first and second slots from a second end of the first slot and a second end of the second slot, the second end of the first slot and the second end of the second slot disposed at another end of the rotor. - View Dependent Claims (10, 11, 12, 13)
