A system for a wind turbine nacelle includes a rotor head, a plurality of blade holders connected to the rotor head, and a shaft having a first end that extends into the rotor head. Linear movement of the shaft causes movement of the plurality of blade holders. The system further includes an electromechanical pitch actuator connected to a second end of the shaft and configured to translate linearly to move the shaft linearly. The system further includes a linear drive system connected to the electromechanical pitch actuator. The system further includes a fail-safe system connected to the electromechanical pitch actuator via the linear drive system. The fail safe system actuates to force the electromechanical pitch actuator rearward to move the blades into a stall blade position.
