| English: The three primary types of wind turbine--Savonius and Darrieus vertical axis wind turbines (VAWTs) and a standard horizontal axis wind turbine (HAWT)--all with three blades, are spinning as if they are in operation in real wind. They are spinning at the same speed (mathematically); 30 rpm. (Photo credit: Wikipedia) |
Advantages of 5-blade wind turbines over 3-blade wind turbines
1) 5-blade wind turbines will greatly improve annual energy production in low wind conditions. For areas with average wind speeds of 11 MPH (5m/s). If you compare annual energy output to conventional 3-blade wind turbine, there is an increase of annual energy output of more than 60%.
2) 5-blade wind turbines will dramatically improve the reliability and safety in high speed wind conditions. The blade rotation speed of a 5-blade turbine is 60% of the rotational speed for a 3-blade wind turbine. 5-blade wind turbines will greatly reduce chance of overspeed control malfunction. This will ensure operational reliability from a long term perspective.
3) The lower blade rotation speed of 5-blade wind turbine will lower wind turbine noise and make 5-blade wind turbines more community friendly than 3-blade wind turbines. Nylon-Fiber Glass High Efficiency blades is aerodynamically designed to regulate themselves, slowing automatically in high winds.
1. Strong Neodymium magnet PMA, the unique winding and multi pole design reduces the start-up torque of the alternator that assures generator to generate electricity at low wind speed. 4.5 mph start up wind speed.
2. Electric over-speed control, no more problematic mechanical furling.
3. Innovative low maintenance two-moving-part system design.
4. Easy to Install, Light Weight and highly reliable.
5. Generator: The generator is built using high-performance rare earth neodymium permanent magnets, so the alternator is compact and light weight with a high power generating efficiency. Number of Blades: 5 Blade Diameter: 4.6 Feet Rated 400W @26 mph More Energy Output at low wind than 3-blade models Max Wind Output: 500W
