In an embodiment, a rotor comprises a plurality of stacked laminations, wherein each lamination includes a plurality of radially extending slots arranged about a circumference of each of the plurality of laminations, and the plurality of radially extending slots in successive laminations in the stack are aligned. A stud member passes longitudinally through at least one hole in the lamination stack, and a plurality of coils are positioned within the plurality of slots. Fewer than all of the plurality of slots have a coil positioned therein, leaving at least three slots empty. Balance members may be placed in the slots that do not have a coil positioned therein to balance the rotor.
