  • Patent number: 10211693
    Abstract: A rotor for an electric machine has a surface with projections. Each projection protrudes from the rotor in an essentially axial direction and is configured to define a groove between the projection and the surface. The groove of one projection of two adjacent projections and the groove of the other one projection of the two adjacent projections is open towards a region between the adjacent two projections. A cover engages in the grooves of the adjacent two projections, and a sealing compound is applied in the form of a fillet seam between the cover and the adjacent two projections. Received in an intermediate space between the cover and the surface is a permanent magnet, and a pouring compound is received in a remaining hollow space defined between the permanent magnet and the cover and/or the permanent magnet and the surface.

  • Patent number: 6908516
    Abstract: A new class of light or reactive elements and monophase ??-matrix magnesium- and aluminum-based alloys with superior engineering properties, for the latter being based on a homogeneous solute distribution or a corrosion-resistant and metallic shiny surface withstanding aqueous and saline environments and resulting from the control during synthesis of atomic structure over microstructure to net shape of the final product, said ??-matrix being retained upon conversion into a cast or wrought form. The manufacture of the materials relies on the control of deposition temperature and in-vacuum consolidation during vapor deposition, on maximized heat transfer or casting pressure during all-liquid processing and on controlled friction and shock power during solid state alloying using a mechanical milling technique.
