• Multi-Stacking Modules
• Build a common model for generator scaling according to rotor size
• The generator module should always be at the bottom of the mast, reducing the top load of the mast and also making the generator more accessible for maintenance.

tubular, cylindrical rare earth magnets aligned in a circle pattern, held by two plates made out of a non ferrous, non magnetic material. magnets are entirely suspended in those plate or in one thick plate, then covered by a sheet of plastic material on both ends. This part is coupled via a universal hole pattern to the VAWT's main shaft and forms the rotor of the generator. above and below this permanent magnet disc lays a stator consisting of either

generator-coil-form- a three phase, multi pole coil pattern, each coil wound with an inner spacing of about the size of one magnet or a serpentine style pattern with one coil being bent into a star shape forming one phase, then another star shaped coil on top with a phase shift. this pattern may be repeated from 3 up to 5 phases. the star shaped coils are easier to wind vs. the many single rather round coils. the star shaped phases consist of just one piece of copper wire and don't have to be daisy-chained like the many coils in 1.

(: graphics to be made, especially for the magnet holder.)

TODO: collect old hard disk drives, dissassemble and gather the pair of neodymium magnets. There are 4 magnets in one HDD

Alte Festplattenmagnete können eine Basis für ein Generatordesign bilden, weil oft überflüssig und verfügbar → Recycling. Nachteil: Begrenzte Flussdichte bedingt durch die flache Bauform. Die Größe ist aber ideal für einen mehrpoligen Generator.
