  • Direct-drive wind turbine including multiple bearing sets and inner and outer frame structure members axially extending through a generator core for supporting the generator and rotor hub
    Patent number: 11434877
    Abstract: Direct-drive wind turbines (160) are disclosed. The wind turbine comprise a generator (3) mounted on a frame (1), the generator (3) comprising a generator stator (32) and a generator rotor (31) configured to rotate about a rotation axis (RA), the frame (1) has a protruding portion (11) extending beyond the generator (3), the protruding portion (11) comprising a first structure and a second structure; wherein the first and second structures are configured to rotate relative to each other and about the rotation axis (RA); wherein the first structure is attached to the generator stator (32) and the second structure is attached to the generator rotor (31); a brake system (2) attached to the first and second structures, the brake system (2) being spaced away from the generator (3) along the rotation axis (RA). Also disclosed are methods (200) for braking a direct-drive wind turbine (160).
