Abstract

The invention relates to a wind power generator, which comprises a coil assembly, magnetic steel assemblies, a rotating shaft and an impeller, wherein the magnetic steel assemblies are arranged at two sides of the coil assembly; the coil assembly is shaped as a disc, and the disc-shaped coil assembly is provided with a circuit for cutting magnetic induction lines; each magnetic steel assembly comprises magnetic steel and a magnetic yoke which are respectively shaped as a disc, a plurality of magnetic poles are uniformly arranged on each magnetic steel at intervals, each magnetic steel is arranged at one side of each magnetic yoke, one surface, where each magnetic steel is arranged, on each magnetic yoke, faces to the coil assembly; the rotating shaft passes through the coil assembly and the circle centers of the magnetic steel assemblies at two sides of the coil assembly, and the circle center of the magnetic yoke of each magnetic steel assembly is connected with the rotating shaft; and the impeller is connected to the rotating shaft. The wind power generator disclosed by invention has the advantages of high magnetic field density, high uniformity, capability of realizing multigroup input and free combination of coils, high wind power utilization rate and low start wind power.

Description

technical field [0001] The invention relates to a wind-driven generator, specifically a wind-driven generator with small start-up force, wide adaptable speed (wind force) range, high energy utilization rate, light structure, low cost and low calorific value. Background technique [0002] Wind energy is a renewable new energy source with the advantages of no pollution and environmental protection. In this era of advocating energy conservation and environmental protection, how to utilize wind energy has become a very important research topic. In the prior art, wind power generators have been widely used, but there are still many defects in the current wind power generators, for example: the starting torque of the wind power generator is relatively large, and when the wind force is small, the impeller of the wind power generator When the wind is strong, in order to prevent the rotor from running too fast, the angle of the fan blades has to be changed to reduce the utilization ...
