Abstract:
A permanent magnet rotor for use on an electrical generator comprises a hub having an outer peripheral surface and an inner peripheral bore centered on an axis. The inner peripheral bore is provided with a screw thread at least over a portion of an axial dimension. Permanent magnets are mounted on the outer peripheral surface of the hub. A containment band is positioned radially outwardly of the magnets, holding the magnets and the hub together. The hub, a generator rotor incorporating the permanent magnet rotor, and a generator incorporating the permanent magnet rotor are also disclosed and claimed in this application.
