<p>The wind energy plant has a rotor (12) with adjusting rotor blades (13) for drive of a generator (14). An adjusting device (3) is provided for the rotor blade with an actuator (4), which has an excitation coil. The adjusting device has a torque- degradation device, which reduces a drag moment of an actuator. The torque-degradation device has a current distributor, which switches a current by the excitation coil.</p> |
