Rotor for an electric machine
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.
