Arrangement for pitch angle adjustment of rotor blade, comprises rotatably mounted arrangement section, which is arranged in hub, where pitch angle adjustment drive is supplied with electrical energy from generator

摘要

The arrangement comprises a rotatably mounted arrangement section, which is arranged in a hub. A pitch angle adjustment drive is supplied with electrical energy from a generator (2). Energy is generated by the generator by rotational movement, particular by the direct conversion of a rotational energy of the pivoted arrangement section. An independent claim is also included for a machine, particularly a wind turbine for converting kinetic energy of a moving fluid, particularly air or water, into rotary motion.
