Patent number: 9297360Abstract: The disclosure relates to a wind turbine having a machine support (5), a rotor (6) which can be driven by wind (13) to rotate about the rotor axis (7) and is mounted so that it can rotate on the machine support (5) about a rotor axis (7). The rotor includes a rotor hub (8) and several rotor blades (9, 10) which extend respectively in the direction of a blade axis (11, 12) running transverse or essentially transverse to the rotor axis (7). The rotor blades (9,10) are mounted so that they can rotate on the rotor hub (8) about the respective blade axis (11, 12). Blade angle adjustable drives (17, 18) are arranged on the rotor (6) and enable the rotor blades (9, 10) to rotate about the blade axes thereof (11, 12). A blade angle control device (24) is coupled to the blade angle adjusting drives (17, 18) and can control the blade angle adjusting drives (17, 18). An electric generator (15) is mechanically coupled to the rotor (6) and can be driven by the rotor to generate electric energy.Type: GrantFiled: October 14, 2010Date of Patent: March 29, 2016Assignee: SSB Wind Systems GmbH & Co.
