Generated core for 12 volt wind?

In the back of my shop, there is a 2500 watt generator with a blown motor. My boss said I could have it. Could this be used as a 12volt wind turbine (with proper regulation or are the RPMs needed to make a generator core too high for this idea to work? Worse comes to worse, I'll chuck a Harbor Frieght motor on it.  Thanks...Larry

A 2500 watt generator would take about a 5 HP motor to operate it.  To derive that much power from a wind turbine in a 10 MPH wind would require blades about 30 feet in diameter.

Thank you for taking the time to reply.  My luck has been good on this project. But a did have a feeling that this was a no go. I'll size the old motor and pick one up.  Gonna need a generator for final assembly anyhow.  You will be hearing a lot more from me coming up. My prefab/ kit cabin is done, I'm in the process of rearranging my shop for wind,solar water and power and RMH builds. Thank you Larry
