The authors have invented the superior wind turbine generator, which is composed of the tandem wind rotors and the double rotational armature type generator without the conventional stator. The large-sized front wind rotor and the small-sized rear wind rotor drive respectively the inner and the outer armatures of the generator, in keeping the rotational torque counter-balanced. Such operating conditions enable to make the output higher than the conventional turbine and to keep the output constant in the rated operating mode without the brake and/or the pitch control mechanisms. This paper discusses mainly the effect of the wind rotor profile (camber and twist) on the diameter ratio and the axial distance between both wind rotors.
