Yaw Drive Design Principles<\/h2>\n
The yaw drive worm gear reducer drives a pinion or ring gear that rotates the nacelle horizontally. For small turbines (1\u201350 kW), the nacelle is light enough that a single worm gear stage provides adequate yaw torque. The worm’s self-locking property holds the nacelle facing the wind against side-gust forces without continuous motor current \u2014 reducing yaw control system power consumption, which is critical for off-grid turbines where every watt counts. Without self-locking, a holding brake or continuous motor current would be required, wasting energy and adding mechanical complexity.<\/p>\n
