<p>The device has rotor blades (3) mounted to rotate on a rotor with electrical devices in the rotor hub (2), such as an actuator (4, 5) for the rotation of the rotor blades. On drop-out of a power supply to the electrical devices, a rotor brake is activated (11). The rotor blades as a result of the braking torque of the rotor brake are rotated into a feathered position by the inertia. An independent claim is included for a method for braking the rotor of a wind energy plant.</p> |
