The authors invented the unique wind power unit composed of the large-sized front wind rotor, the small-sized rear wind rotor and the peculiar generator with the inner and the outer armatures. The rotational torques of both armatures/wind rotors are counter-balanced, while the rotational speeds and the directions are adjusted automatically in response to the wind conditions. The prototype unit is composed of the tandem wind rotors, whose front and rear diameters are 2 m and 1.33 m, and the double rotational armatures type synchronous generator. The unit was setup at the roof of an isolated building at Kitakyushu city in Japan. The field test results proved that this type unit may be effective to get the sufficient output if the profiles of the wind rotors and the peculiar generator are optimized.

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.
