Rotor i.e. three-bladed rotor, for wind power generating plant, has component e.g. magnet, influencing electrical signal, and electronic unit determining angular position of rotor blade from influenced signal with respect to housing part

摘要

The rotor has a component e.g. rod-shaped sensor (21), formed in a curve shape and arranged at a region of an opening of a housing part (16). A curved progression is coaxially directed towards a longitudinal axis of a rotor blade, and an electronic unit (22) produces electrical signal, which is guided through the component. Another component e.g. magnet (25), influences the electrical signal, which is fed to the electronic unit. The unit determines angular position of the rotor blade from the influenced signal with respect to the housing part.
