  • Publication number: 20220109342
    Abstract: An aircraft electric machine includes an electric stator that surrounds and supports a rotor. A housing defines a sealed chamber enclosing the electric stator and is configured to maintain an absolute pressure of a gas within the chamber as an aircraft with the aircraft electric machine changes altitude.

  • Publication number: 20050099079
    Abstract: Rotor construction that comprises rotor a centrally located permanent magnet section having aligned magnet segments 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.

  • Publication number: 20050093391
    Abstract: Method and apparatus for containing and protecting the magnets of a permanent magnet rotor spinning at high speeds without the use of a sleeve and is applicable to all permanent magnet rotors with two or more poles. Magnetic pole pieces are used to mechanically retain the magnets as well as provide a low reluctance path for the magnetic field to travel. The pole pieces and magnets are oriented radially on a hub made of a non-magnetic material such that the flux path of the magnets to the rotor poles is not shorted through the hub or shaft. The rotor poles have a taper angle and are secured to the rotor hub; the pole taper angle trapping the magnets, which have a matching taper angle. End cap pieces are provided to retain the rotor poles and the permanent magnets as an integral magnets/poles subassembly for use in a motor or generator.
