Description

  The present invention relates to a wind turbine generator having a vertical axis type windmill that can receive wind energy from one direction regardless of the wind direction and change it into a rotational motion.

  In recent years, due to the diversification of energy use and improvement of power generation technology, power generation systems that use natural energy such as sunlight and wind power have attracted attention as environmentally friendly clean power generation systems. A horizontal axis type wind turbine represented by a typical type, and a vertical axis type wind turbine represented by a Saponius type or a Darrieus type is put into practical use for a small type. In particular, small wind power generators have a simple structure, and vertical axis type wind turbines that can rotate from any direction are practically used for advertising towers and street lighting.

  Conventionally, this type of vertical axis wind power generator has a larger mechanism for supporting the wind turbine than the propeller type wind turbine when trying to increase the size of the wind turbine in order to obtain a large output. Since it becomes an apparatus, it was necessary to generate power efficiently even with a small size (for example, see Patent Document 1).

  Hereinafter, the wind power generator will be described with reference to FIG. FIG. 6A is a bird's-eye view of a conventional wind power generator, and FIG. 6B is a cross-sectional view of the conventional wind power generator.

As shown in the figure, blades are attached to the rotating shaft 101 erected in the vertical direction and the rotating cylindrical shaft 102 that rotates concentrically with the rotating shaft so as to rotate in the opposite direction. A winding 103 is provided on one of the shafts and a field magnet 104 is provided on the other to form a generator. The output of the winding 103 is taken out by a brush 106 that contacts the outer periphery of the commutator 105. Both the upper and lower ends of the rotating shaft 101 and the lower end of the rotating cylindrical shaft 102 are always levitated by the repulsive force of the magnet built in the bearing frame 108 supported by the support column 107 and are not in contact with each other in the radial direction. By being supported by the magnetic bearing 109 configured, it is possible to generate electric power efficiently by reversing the generator even at a weak wind speed, and there is no friction in the bearing, and wind power can be effectively converted into rotational motion.
