Generator rotor for a generator of a wind turbine or a hydroelectric power plant, and generator, wind turbine and hydroelectric power plant with selbigem

摘要

The invention relates to a generator rotor (5) for a generator (1), in particular a slowly rotating generator, a wind energy plant (100) or a hydroelectric power plant (200). According to the invention, it is proposed that the generator rotor (5) has a rotor belt (15) for holding a plurality of pole shoes, a hub flange (19) for fastening the generator rotor (5) to a shaft, in particular main shaft or gear shaft, the wind energy plant (100), or for attachment on a number of turbine blades of the hydroelectric plant (200), and a support structure (17) which is rotatably connected to the rotor belt (15) on the one hand and with the hub flange (19) on the other hand, wherein the rotor belt (15) made of a metallic material with a first degree of damping (D1), and at least one of: support structure (17) or hub flange (19) consists partially or completely of a material with a second degree of damping (D2), the second degree of damping (D2) being higher than the first one Damping degree (D1).
