Pls which type of dc motor you can advise to get to design wind turbine to generate enough current. Pls am terribly waiting for replies because its my final year project and i want to start it very soon.thanks

How much current do you need to produce?

I am a wind turbine designer. I build 3 phase ac alternators for my wind turbines, which I rectify to dc. If you must use dc, then a 90v treadmill motor is useful.

See my wind turbine instructable and free 3 part tutorial at "http://green-trust.org/freebooks/(Wind Turbine Plans)":http://green-trust.org/freebooks/

I use 3 phase rectified to dc for efficiency.

Hi, you can use a F&P as a 3 phase PMA. You will also have to use a buck converter with a variable duty cycle. The buck converter should run in discontinuous mode. Add a micro to control the duty cycle and call it a MPPT controller. The larger the blade size the better.
I hope this help.

IF you just need DC consider something like this

Hi Amos, can you state the approximate diameter of your intended turbine ?
And the power output you want for example, from a twenty kph wind ?
