People say why not create an array of windbelts but by the time you've got to that stage you might aswell have just brought a wind turbine. Can you imagine having to maintain 100 wind belts?

Can you imagine having to maintain 100 wind belts?

A 10 MegaWatt generator could be just 1 meter in diameter by 1.5 meters long, with other configurations possible depending on what is desired. Plus a ES generator has the option of ramping torque as needed based on wind conditions, so you can start the turbine in low winds with just 1 250kilowatt segment and increase resistance as winds pick up. You cant even do this with SCM generators due to their fixed configuration due to windings. ES generation is the clear winner long term.

A 10MW generator would be just 1 meter diameter and 1.5 meters long (if you choose that configuration from may possibilities) and cost a fraction as much.

Our design of the permanent magnet direct drive wind turbines make the nacelle and the generator separated, and it works quite good. For more information of our wind turbines, pls contact eric@ruiqineng.com. Good information.
