Is a Larger DC Motor Needed for Low Wind Speed Power Generation?

[QUOTE="PNW Hobbyist, post: 6838735, member: 731844"] Yes, the resistance I was referring to is the permanent magnet passing the poles. The prop I was using simply didn't have enough torque to get it spinning with the wind speed I have available in this particular application. That wind is a fixed speed and never changes so I either have to work within those parameters or give up on the idea. Right now I'm at the stage of "Can I even generate enough power here to do anything with it at all?" I was able to find a small prop meant for model airplanes at the local hobby store that finally had enough torque to spin up the motor. I posted my initial question because I don't know much about DC motors and I don't know if this cheap little thing I bought off Amazon for a couple dollars is just such poor quality that it has a higher starting torque than a quality product might have. Looking at the spec sheets for various motors I don't see any metric that would tell me how one differs from another in that regard. Or, if that's just a fundamental function of all DC motors. If for example I could locate a DC motor that has a very low start up torque to get past the attraction of those magnets, does that mean I sacrifice something else in exchange? Is this just the way DC motors work and the higher the output voltage at a certain RPM, the higher the starting torque will be? I am no electrical engineer if that isn't abundantly obvious from my questions. :-) I will go back and read your earlier post and see if that helps me move forward. Thank you for your responses.
