Shaftless multi blade wind turbine

E. Oran (Inventor), Essam Abo-Serie (Inventor)

    Research output: Patent


    The invention relates to a shaftless shrouded multi-blade wind turbine which has turbine blades located at the outer diameter instead of the center. The new wind turbine design simultaneously converts kinetic energy of wind into mechanical and electrical energy with its special designed generator rotor together with the larger blades chord which has its chord increases with distance from the center. The rotors, which haven't axis shafts, belonging to special designed generator, rotates with the fan blades integrated with the rotor in the magnetic shell supporting with bearings. The system makes use of all the advantages of both direct drive and brushless motor technologies. This design has a new concept that allows easy installation on buildings and bridges as it does not need supportive towers and support equipments for the central component of the wind turbine.
