A rotor for an electric machine includes a plurality of magnet stacks having at least five permanent magnets formed into a skew pattern within each of the magnet stacks. The skew pattern has a skew angle and at least two skew steps, and is an angle of rotation about the axis between individual magnets adjacent to the skew steps. The skew pattern may be an axially-symmetric V-shape. The plurality of magnet stacks may have five, six, or eight permanent magnets therein. The number of skew steps may be equal to two or three. The skew angle may be calculated as 360 degrees, divided by the number of skew steps plus one, multiplied by the least common multiple of the number of rotor poles and the number of the plurality of stator slots.
