your welcome my friend
i hope your success

 

Mechaboy, what about a 14 volt cordless drill motor?

They are 300 watts, like this one http://bigskytool.com/DeWalt_DC730K..._DrillDriver_Kit_(Reconditioned)___i2351.aspx.

The only thing is they are geared to 1,500 to 2,000 rpm, and I want 2,500 +.

If I changed the gears wouldn't it work?

Thanks my friend!

yes it would work but it's torque would be more than 0.8 N/m.is it a problem?

 

Hmm, I do not think so. In our prototype we are using a cord drill with MUCH more torque and it's fine. But a cordless drill cannot get up to the 2,500 rpm speed. They are more in the 1,500 rpm range.

We are just spinning a brush that is meeting some resistance. Would there be any problem in using too much torque? I thought that if it spins, it spins.

 

what do you wanna brush?i think with a high torque brushing is easier.

 

Any more pressure and I will not be able to keep up the speed.

I think this is pretty good what you've said anyway.

Maybe I will go to a thicker belt. I've seen 10 mm belts that just wrap around the axle of a motor on one end and turn a brush quite fast.

 

that's nice.i think what you need now is a testing.
