High power aluminum alloy wind turbine can be used in small wind power plants

Adopt direct drive permanent magnet generator, upwind, automatic adjustment of wind direction, gearbox transmission design, the whole machine start wind speed is low, small size, light weight, beautiful appearance, low vibration operation. The motor shell and engine room are cast in one body, the material is aluminum alloy, has the advantages of good heat dissipation, light weight, the surface adopts strict anti-corrosion measures, durable. Suitable for small wind farm, smart grid, micro grid system and other applications.

Products Details

  • ●Safety: The main stress points of the blade are concentrated on the hub, so the problems of blade fallirng off, fracture and blade flying out have been better solved.
  • ● Radius of gyration: Due to its different design structure and operation principle, it has a smaller radius of gyration than other forms of wind turbines, saving space and improving efficiency.
  • ●Generation curve characteristics: The start-up wind speed is lower than that of other types of wind turbines, and the rise of power generation is relatively gentle. Therefore, within the wind speed range of 5~8m, its power generation is 10%~30% higher than that of other types of wind turbines.
  • ● Braking device: The blade itself has speed protection, and can be equipped with mechanical manual brake and electronic automatic brake. In areas without typhoon and super gust, only manual brake needs to be set.
  • ●The casing is made of A3 steel, with small volume, light weight, beautiful appearance and low running vibration.
  • ● Flange installation, good strength, convenient installation and maintenance.
  • ● The blade is made of reinforced FRP, equipped with optimized aerodynamic shape design and structural design, with start-up wind speed and high wind energy utilization coefficient, which increases the annual power generation.
  • ● The tail rudder adopts automatic windward design and straight tail type, with strong typhoon resistance and safe and reliable operation.
  • ●The generator uses the patented Nd-Fe-B permanent magnet rotor alternator. The special stator and rotor design can effectively reduce the resistance torque of the generator. At the same time, the wind turbine has better matching characteristics with the generator and the reliability of unit operation.
  • ● The maximum power tracking intelligent controller can be selected to effectively adjust the current and voltage.

How A Wind Turbine Works

To charge the battery, the output voltage of the solar panel must be higher than the current voltage of the battery. If the voltage of the solar panel is lower than the voltage of the battery, the output current will be close to 0. Therefore, for safety reasons, the peak voltage (Vpp) of the solar panel is about 17V when the solar panel is manufactured, and it is set as standard when the ambient temperature is 25°C. When the weather is very hot, the peak voltage Vpp of the solar panel will drop to about 15V, but in cold weather, the peak voltage Vpp of the solar energy can reach 18V.1、wind turbines body 2、flange seat 3、steel pipe support 4、wind turbine shaft 5、wind wheel hub 6、wind turbines piece 7、resistance of pine nut 8、fairing9、bolt 10、flat washer 11、elastic washer 12、nut 13、stainless steel screw 14、resistance of pine nuts 15、stern rudder hull
