  • SCF Supercritical generator

    Our wind generator adopts SCF supercritical technology which won a gold award in the 37th Salon Eureka in Brussels. This technology significantly reduces generator’s weight and size down to 20% to 30% of the traditional one, and the production efficiency is 10% to 30% higher. This ensures that the generator functions perfectly in small wind condition.
  • SKF bearings

    Our wind turbine adopts two SKF (Svenska Kullager Fabriken) bearings which are produced by the largest bearing manufacturer in the world, with the perfect internal geometric structure, known for its life-time endurance and reliable quality. Ordinary bearings need to be changed every two or three years, while SKF bearings can greatly reduce the maintenance costs on this matter.
  • Low noise

    The design of the rotor blade of our wind turbine absorbs the highlights of the small aircraft’s airfoil, which is compliance with the aerodynamic standards. It provides a more aesthetic look and a higher efficiency and reduces the noise production as much as possible.
  • Double braking protection

    Our wind turbine adopts the double braking protection system, which are the yawing mechanism and the electromagnetic braking system to regulate the rotation of the wind turbine. It is safe and convenient to shut down the whole system both manually and automatically.

Structure and component parts

  1. Generator Part

    It is composed of the patented SCF generator, the nose cone, and the protection cover. We adopt the state-of-the-art SCF supercritical generator, which is installed in the hub, easy to radiate heat and reduce wind resistance. It is made of high-efficiency magnetic materials, special copper alloy, high-strength stainless steel and aeronautic aluminum alloys, which is extremely light in weight and small in size, but with higher power producing efficiency.
  2. Nose Cone & Protection Cover

    Both of them are made of the reinforced aluminum alloy. Nose cone is fixed in front of the rotor blades to reduce the wind resistance and radiate the heat produced by the generator. While the protection cover between the rotor blades and the nose cone to provide extra protection to the generator
  3. SKF Bearings

    Two SKF bearings ensure the reliability the longevity of our generator. Wide temperature ranges: operation in the high temperature (150-350ºC). Long life span, reach up to 60000-100000 hours. User may not change the bearing during the wind turbine using. It can greatly reduce the maintenance costs.
  4. Flange & Blades

    The flange is made of fine steel, used to fix the blades to the rotor. The blades are made of glass-reinforced plastic; efficiently turn the wind energy into the mechanical energy. Every set of the three blades has passed the strict balance test before the shipping. It is important to fix the blades together which belongs to one set to the flange and never mix them up with other blades which belongs to another wind turbine.
  5. Furling Mechanism

    The mechanism is composed of the 360 rotation yaw shaft, the tail rob and the rudder blade, which are made of the manganese steel and aluminum alloy. It combines the high strength and the lightness, thus is able to react to the gusts rapidly.
  6. Rectifier/Dump Load Controller & Dump Load Box

    The controller controls the process of which the AC produced by wind turbine being rectified into DC and eventually charges the battery bank with DC. It also controls the switching on and off of the dump load to protect the system against the risk of being overloaded with too much power.
    The metal box design of the dump load radiates the heat of the resistance inside quickly via the air convection. So there is no need for an extra fan.
  7. Off-grid Inverter & On-grid Inverter

    Our off-grid inverter adopts SPWM (Sinusoidal Pulse Width Modulation) technology, is able to invert DC with higher efficiency into AC with stable frequency and voltage, and filters the noise as well. It is used in the off-grid power system.
    Our on-grid inverter adopts MPPT (Maximum Power Point Tracking) technology and IGBT (Insulated Gate Bipolar Transistor), is able to invert DC with a high power producing capacity and a wider AC voltage output range. It connects to the public grid and there is no need for any power storage device.
