A rotor for an electric machine includes a circular rotor base having a first surface, a second surface, and a circumferential outer edge extending from the first surface to the second surface, a plurality of magnets disposed proximate the circumferential outer edge of the circular rotor base, and a plurality of flux guides. Each magnet has a first surface and a second surface. The first surface of each magnet is attached to the first surface of the circular rotor base, and the second surface of each magnet defines a first shape. Each flux guide is attached to the second surface of a different magnet and has a first surface attached to the second surface of a first respective magnet and a second surface opposite the first surface. The second surface of each flux guide defines a second shape different than the first shape of the magnets.
