  • Rotor cap for electric generators
    Patent number: 10749401
    Abstract: A rotor cap for an electric generator, e.g., a high-speed turbogenerator, is disclosed, along with a production method for such rotor cap. The rotor cap is at least partially made of fiber-reinforced plastic material. The rotor cap may have cooling fluid passages, e.g., extending in an axial direction, in the area of the fiber-reinforced plastic material.

  • Two-layer high-voltage insulation system and electrical machine
    Patent number: 10284042
    Abstract: By using an electrically conductive PTFE fabric, high-voltage insulation systems are simplified and can be made thinner, also improving the thermal conductivity. The insulation material is in two layers, each with a hydrophobic and a hydrophobic region, and the hydrophobic regions of the layers are opposed.
