Blades, motors and other mechanisms for 2000 w small wind turbines

Oct 08, 2018

2000 w small wind turbines generally consist of wind turbines, generators, speed control and steering mechanisms, parking mechanisms, towers and cables, controllers, batteries, inverters, etc. Wind turbines are mostly composed of 2 to 3 blades, which are components that convert wind energy into mechanical energy.

 

There are two kinds of materials for the wind turbine blades of 2000 w small wind turbines. One is glass fiber reinforced plastic material. Generally, glass fiber cloth and blended epoxy resin are used for manual paste in the model. Some filling materials are added to the inner cavity. Paste is suitable for blades of different shapes and variable cross-sections; it also uses mechanized production of equal-section blades to improve the efficiency and product quality of the blades.

 

The 2000 w small wind turbine generally uses a permanent magnet alternator, and the alternating current generated by the wind turbine driven generator is rectified to become a direct current that can be stored in the battery. In order to obtain energy from the wind, the rotating surface of the wind wheel should be perpendicular to the wind direction. In a small fan, this function is realized by the tail of the wind turbine as a steering mechanism.

 

At the same time, as the wind speed increases, the speed of the wind wheel is limited. Because the structure of the small wind turbine is relatively simple, the impeller side-bias speed regulation mode is generally adopted. Therefore, when the wind speed is large, especially the battery is already full. In the case, the wind turbine should be manually controlled to stop. In some 2000 w small wind turbines, a manual brake mechanism is designed. In addition, a side-to-side stop mode can be adopted, that is, a soft rope is fixed on the tail fin. When the machine needs to be stopped, the tail fin is pulled to make the wind wheel face the wind direction. In order to achieve the purpose of parking.
