Abstract
An electric machine includes a stator, a rotor, and magnets. The stator includes multiple flux members having ferrous material. The rotor is configured to rotate relative to the stator and spaced from the stator by an air gap. The magnets are rigidly mounted to the flux members of the stator. At least a first magnet and a second magnet of the magnets includes an elongated axis parallel to a radius of the rotor and a minor axis perpendicular to the elongated axis, and a first pole of the first magnet having a first polarity and positioned along the minor axis to face a first pole of the second magnet having the first polarity.
