A rotor for a permanent magnet motor includes a rotor body and a plurality of permanent magnets carried by the rotor body. The rotor body has an outside rotor surface with a plurality of dovetail slots formed on the outside rotor surface. Each magnet is fit within one of the slots, protruding outward of the outside rotor surface in a radial direction. According to another embodiment, a rotor is provided having a rotor body that carries a plurality of magnets on its outside surface, and end caps that are fastened respectively to longitudinal ends of the rotor body. The end caps each have a angled rim surfaces that overhangs an end portion of the outer magnet surface of each of the magnets to retain the magnets onto the rotor body. The angled rim surfaces and the magnets can be configured such that by drawing the end caps tightly against the rotor body by use of fasteners, the magnets are wedged down onto the rotor body by the angled rim surfaces.
