ABSTRACT:
A yaw drive assembly for a rotatable system includes an input shaft configured to receive a torque from a yaw drive motor coupled within a body of the rotatable system, wherein the torque facilitates rotating the rotatable system about a yaw axis. The yaw drive assembly includes at least two output shafts configured to receive the torque and transmit a rotational yaw force to the rotatable system, and a differential gear stage operatively coupled to the two output shafts, wherein the differential gear stage includes a differential planetary gear configured to drive a pinion coupled to each of the two output shafts.
