Abstract
The invention relates to the shaftless horizontal axis wind turbine for generating electricity from the flow of fluid. The major components of the shaftless horizontal axis wind turbine consist of a stator and a rotor. The major components of the stator consist of a set of copper coils installed along a circular circumference of the stator frame and electrically connected as the Star connection (3-phase) circuit. The major components of the rotor consist of at least a set of the turbine blade, roller, and magnet set. The turbine blade has optimized an obtuse angle (θT) of the turbine blade holder and a rotation angle (θR) between the turbine blade holder and turbine blade to create the open channel in the middle of the shaftless horizontal axis wind turbine, which is shaped like a nozzle without shaft at the center of horizontal axis wind turbine.
