1. A rotor core lamination comprising:
a plurality of salient poles, each of the salient poles comprising:
a pole body having a central axis in a radial direction of the rotor core lamination; and
a pole shoe extending radially outward from the pole body, wherein the pole shoe has a pole shoe arc, and a central point of the pole shoe arc is offset from the central axis;

wherein the rotor core lamination is arranged and configured to operate with a stator, the stator comprising a plurality of stator slots arranged to accommodate stator windings, wherein the plurality of salient poles includes a first salient pole and a second salient pole, the first salient pole being next to the second salient pole, and wherein the central point of the pole shoe arc of the first salient pole is offset with respect to the central axis of the first salient pole by one quarter of a stator slot pitch toward the second salient pole, and the central point of the pole shoe arc of the second salient pole is offset with respect to the central axis of the second salient pole by one quarter of the stator slot pitch toward the first salient pole.
