Abstract
An illustrative embodiment of the present invention is concerned with a permanent magnet rotor for an electric machine provided with an internal stator and a coaxial external rotor. To overcome the drawbacks associated with the use of an adhesive to mount the permanent magnets to the rotor body, permanent magnet spacing and retaining elements are mounted to the inner surface of the rotor, between adjacent magnets.
