Qingdao Richuan precision Machinery Co,Ltd. is a manufacture enterprise which develops, manufactures and sells small and medium complete set of wind turbine. Normally we produce the vertical axis and the horizontal axis wind-driven generator.

  Our company has design department and system configuration team, thus we can provide power supply system solutions depending on various customers' requirements. Moreover, we have engineering department, our engineers can provide product's installation guidance and training to our customers

1..Low starting torque

2.Low start wind speed

3.Low speed permanent magnet generator

4.No vibration & low noise

5.All of our products confirm to CE

6.PWM constant voltage recharge function provides stable output

7.Reliable wind power system by multifunction controller

8.On-grid or Off-grid wind power system optional

9.2-year warranty for generator and 18-20 years service life.

10.Electronic brake and manual brake, optional.

11.High efficiency and Low mechanical resistance energy loss.

12. Special sealed wind turbines, moisture, sand and water proof

The generator of our company is designed and producted by ourselvs.

Cabin is formed by  Bearings ,gearbox,electronic controller,generator and  cooling element.

Magnetic  designed professionally. Work  wind speed 3 m, low wind speed can generate electricity.

Bearings , generator adopt NdFeB strong permanent magnetic material .  

Blades are made by FRP With hardness, corrosion resistance, anti-wind ability

FRP With hardness, corrosion resistance, anti-wind ability

FRP With weight  light , long years used

1.If the system meet problem ,and the wind turbine is running ,it can prevent the wind turbine race rotation .

2.have the auto-protection function of the batteries Reverse protection, anti-disconnect battery protection, battery damage protection.

3.when the charge current is high in strong wind,controller can load the wind turbine automatically. And charging the battery with low current.

4.The wind turbine brake automatically when the battery bank voltage get to rated voltage 125%; and stop charging the batteries.

5.the wind turbine get back charging the batteries when the the battery bank voltage get to rated voltage 108%
