If the wind turbine in the poster does not spin in strong winds, the problem may be:
1. Check if the generator's 3-phase AC line is shorted
2. If the fan blades are installed upside down
3. If the engine is burned out
4. Problems with bearings
Problems with. two more fans of the original poster:
When people don't feel wind on the ground but the blades are spinning very fast, that's normal, because people on the ground certainly feel that there is no wind. There is no wind, and when the fan is several meters high, the wind direction is different. The main thing is to see if the leaves move. If the leaves are visibly windy, it is normal for one fan to spin so slowly, but the other one is not spinning. . What is the distance between the two units? If it is too close, it is normal because two units cannot be installed too close to each other, as this will affect its effectoverall. There should be no high-rise buildings when installing the fan, and it is best to install it in an open area.
Regarding these situations, could you please please check if there are any of the above situations?
