The rotor includes a shaft extending along a rotational axis, a plurality of first core portions each including a plurality of laminations stacked contiguously on the shaft, and a second core portion coupled between each of the first core portions. The first core portions and the second core portion cooperating to define a rotor magnetic core. A plurality of windings is coupled to the rotor magnetic core, and an air flow path is partially defined by the first core portions, the second core portion, and the shaft. The air flow path includes an axial portion that passes through the shaft axially along the rotational axis and a radial portion that extends radially outward through the second core portion.
