Welcome to Fieldlines.
I tried posting yesterday, but I don't think it got through. Anybody else trying to respond to this posting will have to edit the line with the subject in it because the software thinks it's too long. (Sorry Cico, it's not your fault).
What I said yesterday, briefly, is that the motor, when converted, will probably not be appropriate for a savonius turbine. Although there is some useable torque in a Sav, they don't turn fast enough. A strong wind would be necessary just to reach cut-in speed.
Motor conversions do work well when mounted to a HAWT, because both need to turn at 200-500 RPM. If you were to do something like that, you could expect at least 200Watts from your converted motor, perhaps even 400W. It depends greatly on details inside the motor: how it's wired, sizes of bearings, size of the rotor, and so on.
If you want to give more pictures, I could tell you a bit more about converting it. Then you can decide if you want to go ahead with it or not, and if you are interested in a HAWT turbine, instead of a VAWT.
