An electric machine (20) having a rotor (24) with a rotor core (30) formed out of magnetically permeable material and defines a plurality of poles (32). Each pole includes a plurality of discrete axially extending magnet slots (36, 38) with at least one permanent magnet (40, 42) in each magnet slot. Each pole (32) has a radial centerline (34) and includes a plurality of voids (86, 88, 90) defined by the rotor core. For each pole the magnet slots include at least one central magnet slot (36) and two outer magnet slots (38), the outer magnet slots (38) are positioned on opposite circumferential sides of the radial centerline (34) of the pole and are at least partially positioned closer to a radially outer perimeter of the rotor core than a radially outermost edge (60) of the at least one central magnet slot (36). Each of the plurality of voids (86, 88, 90) is spaced from each of the magnet slots (36, 38) and positioned circumferentially between the outer magnet slots (38) and radially outwardly of the at least one central magnet slot (36).
