DC motor as generator.

[7yler]

I am attempting to build a wind turbine, as many have successfully. I have read that a permanent magnet dc motor out of a treadmill will serve well as the generator for the turbine. I'm not very electrically savvy, but I'm attempting to learn. I have posted pictures of the motor, and the multimeter that I'm using. I hooked up the red wire on the motor to the red wire on my meter, and the black wire on the motor to the black wire on my meter. I then chucked the spindle of the motor and spun it in my drill to see if I could get a reading on the meter. I had no reading on any of the "DC V" settings, and no reading on any of the "AC V" settings. BUT, I did have a reading of around 10 on the "12A" setting. I tested all settings turning the motor clockwise, and well as ccw. What does this mean? Am I able to use this as a generator for a wind turbine? Thanks for any help.

What does "chucked" mean? That's designed to run at 7,100 rpm and 2.5 hp. You'll need some serious effort to make it show much of an output. A pull-string like on a lawnmower might do it.

Should work, though.

Chucked, as in mounted the spindle and turned it. A pull string? I don't quite follow.

Sorry, your picture is so big, some of your post got cut off - you used a power drill you say? I would think you could register some current (the amps), but without any load on it such as a resistor, you won't register any voltage.

Nice motor.

It is probably working OK if you can get 10 amps out of it as a generator.

Your multimeter requires you to move the red wire to the VOLT_OHM position to read voltage. Did you do this?

Have you tried to use it as a motor by attaching it to a 12 volt battery?
