How are motors and drives used in a wind-turbine nacelle?
That is, the harsher the conditions the turbine faces, the more yaw capacity it needs. Then too, a smaller diameter yaw ring requires more torque and a higher gear ratio, assuming similar-size rotors. To illustrate, Siemens''s latest turbines, from its D3 platform, use 12 x 1.5 kW yaw motors, while the turbines from its large offshore D7 ...
