  • Blade pitch angle adjusting apparatus for a wind turbine
    Patent number: 9644607
    Abstract: A wind turbine blade pitch angle adjusting apparatus for adjusting the pitch angle of a blade of a wind turbine is provided. The apparatus includes an electric pitch motor able to output a maximum motor torque Tm and a pitch brake assembly able to generate a maximum brake assembly torque Tb. The pitch brake assembly includes a plurality of individual pitch brakes each able to generate a maximum individual brake torque Tsb, the maximum brake assembly torque Tb is the sum of all maximum individual brake torques Tsb, and the maximum motor torque Tm is higher than the maximum individual brake torque Tsb of any one of the pitch brakes.
