  • Radially embedded permanent magnet rotor and methods thereof
    Patent number: 9882440
    Abstract: In one embodiment, a permanent magnet rotor is provided. The permanent magnet rotor includes a shaft comprising an outer diameter, a first hub coupled about the shaft outer diameter, and a first plurality of pole pieces positioned radially about the hub. The rotor further includes a plurality of permanent magnets positioned radially about the hub. The plurality of pole pieces and the plurality of permanent magnets define a rotor outer diameter, and the rotor outer diameter is magnetically isolated from shaft.
    Type: Grant

  • Radially embedded permanent magnet rotor having magnet retention features and methods thereof
    Patent number: 9362792
    Abstract: In one embodiment, a permanent magnet rotor is provided. The permanent magnet rotor includes a substantially cylindrical rotor core including an outer edge, an inner edge, and opposed first and second ends. The rotor further includes a first wall and a second wall defining at least one radial aperture extending radially through the rotor core. The rotor further includes at least one permanent magnet positioned within the at least one radial aperture. A first indentation is formed in one of the at least one permanent magnet and the first wall, the first indentation defining a first space between the at least one permanent magnet and the radial aperture first wall. The rotor further includes a first material positioned within the first space, the material configured to substantially prevent movement of the permanent magnet relative to the at least one radial aperture.

  • ELECTRIC MACHINE AND ASSOCIATED METHOD
    Publication number: 20150061441
    Abstract: An electric machine includes a machine housing and a stator disposed at least partially within the housing. The electric machine also includes a radially embedded permanent magnet rotor disposed at least partially within the housing and an endcap. The rotor has at least one radially embedded permanent magnet that is configured to provide increased flux to reduce motor efficiency loss. The endcap is operably connected to a distal portion of the rotor.
