GENERATOR ROTOR FOR A GENERATOR OF A WIND-DRIVEN POWER PLANT OR A HYDROELECTRIC POWER PLANT, AS WELL AS A GENERATOR, A WIND-DRIVEN POWER PLANT AND A HYDROELECTRIC POWER PLANT WITH SUCH A GENERATOR Russian patent published in 2020 - IPC H02K1/30 H02K7/18 F03D9/25 F03B13/08 

FIELD: electrical equipment.

SUBSTANCE: invention relates to the electrical equipment. Generator rotor (5) comprises band (15) for fixing multiple pole shoes, hub flange (19) for fixation of rotor (5) on shaft and bearing structure (17), which is connected without possibility of rotation with band (15) of rotor on one side and with flange (19) of hub on other side. Rotor band (15) is made of metal material with first degree (D₁) of damping. At that, at least one of elements – bearing structure (17) or flange (19) of hub – is partially or completely made of material with second degree (D₂) of damping. Second degree (D₂) higher than first degree (D₁) of damping.

EFFECT: improved vibration characteristics.
