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! Ari
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.
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.
