A pitch assembly (66) for use with a wind turbine (10) including a rotor (18) and at least one rotor blade (22) coupled to the rotor (18) is provided. The pitch assembly includes a pitch drive system (68) coupled to the rotor blade for rotating the rotor blade about a pitch axis (34), and at least one sensor (70) mountable with respect to the rotor for sensing an overspeed of the rotor, the sensor is communicatively coupled to the pitch drive system, and the pitch drive system configured to rotate the rotor blade when the sensor senses rotor overspeed. |
