    Abstract: The present disclosure provides a method for manufacturing a stator which includes the following steps: (1) providing a plurality of stator laminations; (2) stacking the plurality of stator laminations in a stator housing; (3) providing a plurality of conductors; (4) sliding at least two linear portions of each conductor into a corresponding dual position slot for the linear portion; (5) applying a jig to the plurality of dual position slots so as to close the dual position slots into a closed position. The plurality of stator laminations defining a plurality of dual position slots being in an open position when the stator laminations are stacked in the stator housing.

    Abstract: A rotor for an electric machine comprises a rotor core that defines a rotor slot having a central portion and an end portion. The end portion has a maximum width that is greater than a maximum width of the central portion immediately adjacent the end portion. A perimeter of the rotor slot at the end portion includes a plurality of segments extending between a first extremity at the maximum width of the end portion and a second extremity at the maximum width of the end portion. The plurality of segments include segments with different radii that decrease in magnitude from the center axis to the first extremity, and from the center axis to the second extremity.
