Technical advantages　　
  • Simple structure、reliable operation
  • Direct drive, no gearbox
  • Adopting synchronous pm magnet generator, low consumption of generator, high efficiency of power generation.
  • Nacelle can provide positive pressure and filtered air to protect generator and control system from salted wind.
  • Full power frequency conversion can provide high quality of power source fed into Electric Network.
  • Normal operation life of 20 year
  • Low maintenance and low cost
  • High adaptability can be used to generate power in land, beach and off-shore
  • Maximum wind speed 70 m/s
  • Can get into the components in bad weather.
  • Low weight, can be installed by normal crane
Power curve
　　
wind-turbine specification
　　
The generator
　　he generator is a multi-pole permanent magnet generator and is directly mounted to the hub. The magnets take care of the rotor excitation so no external field excitation is needed……

The main bearing
　　The main bearing is a specially designed two row cylindrical roller bearing of large diameter. The inner non-rotating ring is mounted to the generator stator. The outer rotating ring is mounted between the hub and generator rotor……
The nacelle
　The nacelle is a compact nodular cast iron construction which houses the yaw mechanism, a service hoist and a switch board. Both generator and tower are flanged to the nacelle.
The hub
　　The rigid rotor hub is a nodular cast iron structure mounted onto the main bearing. Blades are connected to the hub using a four point pre-stressed ball bearing. It is large enough to provide a comfortable working environment…….
