Abstract

A rotor for a rotating electric machine is described. Embodiments of the apparatus may include a rotor core comprising a plurality of slots, the rotor core comprising a circumference, a first winding comprising a first termination end exiting the rotor core at a first of the plurality of slots, a second winding comprising a second termination end exiting the rotor core at a second of the plurality of slots, wherein the second of the plurality of slots is 120 degrees around the circumference of the rotor core relative to the first of the plurality of slots, and a third winding comprising a third termination end exiting the rotor core at a third of the plurality of slots, wherein the third of the plurality of slots is 240 degrees around the circumference of the rotor core relative to the first of the plurality of slots.
