Patent ID: 8506254

Claim:
An electromagnetic machine comprising: a stator comprising a member consisting of at least one of: (a) an electrically conductive wire winding, or (b) a magnet; and a rotor comprising vanes including stacked layers of at least one elongated fiber, the at least one fiber having a continuous length of at least five centimeters, the rotor further comprising a member consisting of at least one of: (a) an electrically conductive wire winding, or (b) a magnet; the rotor operably rotating adjacent the stator and electromagnetism passing between the rotor and the stator during the rotation; wherein at least one of the rotor vanes has a substantially triangular and hollow shape with its apex being adjacent a periphery of the rotor, and spaced apart leading and trailing fiber walls of the at least one rotor vane diverging away from the apex.
