Abstract
A rotor construction may comprise a rotor with a centrally located permanent magnet section having aligned magnet segments and having a central hole throughout its length. A thin rod of magnetic steel is located in this central hole to support the permanent magnets from within. At each end of the rod are located threaded sections for attachment to supporting end stubs. A high strength steel sleeve is interference fit over both the magnets and the end stubs to provide a mechanical link from stub to stub. The guide rod insures that the end stubs and central magnet are concentric during initial processing, prevents relative motion between the rotor components and provides support for the magnet once the sleeve is installed.
