Abstract
The invention relates to a huge magnetic suspension vertical shaft rare-earth permanent magnet wind-driven generator comprising a wind turbine, a driving shaft, a magnetic separator, a generator, a radial magnetic suspension bearing and an axial magnetic suspension bearing. The axial magnetic suspension bearing is adopted for axially bearing the dead weights of the wind turbine, a generator rotor and the driving shaft, and the radial magnetic suspension bearing is adopted in the radial direction, thereby the rotation part of the whole wind-driven generator completely realizes magnetic suspension. Because the diameter and the height of the wind turbine are not less than 50m, the dead weight of the wind-driven generator is greatly reduced by adopting a steel cable oblique-pulling structure so that the huge wind turbine can be started under the wind speed less than 1m/s, thereby the utilization rate of wind energy can be greatly improved; meanwhile, the production and running cost is also reduced. By adopting a magnetic clutch, the wind-driven generator can ensure safe running at a supernormal wind speed. The rare-earth permanent magnet wind-driven generator produced by rare-earth permanent magnet materials can effectively improve a generation capacity. Vanes produced by carbon fiber composite materials have light weight and high strength and prolong the service life. The huge magnetic suspension vertical shaft rare-earth permanent magnet wind-driven generator has the advantages of no mechanical friction resistance, no noise, small starting wind power, simple structure, low maintenance cost, easy industrialization realization and convenient popularization and application.
