Generator rotor for generators of wind power plants or hydro power plants, generators, wind power plants including them, and hydro power plants

摘要

The present invention relates to a generator 1 of a wind power plant 100 or a hydroelectric power plant 200, in particular a generator rotor 5 for a low-speed rotating generator. According to the present invention, the generator rotor 5 is for fixing the generator rotor 5 to the rotor belt 15 for supporting a plurality of pole shoes, the shaft of the wind power plant 100, especially the main shaft or gear shaft. , Or a hub flange (19) for fixing to a plurality of turbine blades of a hydroelectric power plant (200), and a support structure (17), the support structure on one hand on the rotor belt (15) and on the other hand Each of the hub flanges 19 is rotatably connected to each other, in which case the rotor belt 15 is made of a metal material having a first damping ratio D ₁ , and at least one of the support structure 17 or the hub flange 19 is at least partially made of a material having a second attenuation ratio (D _2), the second attenuation ratio (D ₂₎ is higher than the first attenuation ratio (D _1).
