What is the name of that small household wind turbine's infinite steering mechanism with the wi

The mechanism of small household wind turbines that can infinitely turn with the wind is usually called a yaw system or rudder. The main function of this mechanism is to allow the wind turbine to automatically adjust the direction of the blades as the wind direction changes to ensure that it always faces the wind direction, thereby maximizing the use of wind energy for power generation. The rudder, usually located at the tail of the generator, accomplishes this function by sensing changes in wind direction and adjusting the direction of the entire body accordingly. This design not only improves power generation efficiency, but also reduces potential damage to the generator caused by changes in wind direction.
