In order to allow the impeller to naturally align with the wind direction, wind turbines usually use steering devices. For large wind turbines, motor-driven wind direction tracking systems are generally used. The entire yaw system consists of a motor and reduction mechanism, a yaw adjustment system and a twisted cable protection device. The yaw adjustment system includes a wind vane and yaw system adjustment software. The wind vane has a corresponding pulse output signal corresponding to each wind direction. Its yaw direction and yaw angle are determined through the yaw system software, and then the yaw signal is amplified and transmitted to the motor, and the wind turbine platform is rotated through the deceleration mechanism until it is aligned. Until the wind direction.
The original back (inward) side of your fan is the side facing the wind. It is recommended to use a three-blade fan with a diameter of about 1.5 meters. Are they basically fans like this? The blade shape of the fan used for blowing is different from the blade shape of the fan blade. It should be a leaf shape similar to the wings of an airplane
