Pole element for axial shaft rotatable rotor for electrically-excited synchronous generator, has pole unit whose aspect ratio between axial length of pole unit and pole component are provided as function of flux ratio

摘要

The pole element has an electrical conductor that is wound in a pole unit (119), in order to focus the current flow through the electrical conductor. A pole component is associated with the pole unit (121), when current flows through the electrical conductor to a stator (125) in a space adjacent to the pole element region (123) outside of the pole element. The aspect ratio of the pole unit between the axial length of the pole unit and the axial length of the pole component is provided as a function of flux ratio between pole element and the pole component. The radial position is provided with a radial range considered cross-sectional shape of the pole unit extending in the axial direction. A portion of pole element edge connection of the pole unit is provided in a different area than the axial pole element edge connection of the pole component. An independent claim is included for rotor for electrically-excited synchronous generator.
