SMALL 3-6VDC SCIENCE FAIR MOTOR PKG(2)
This small 3-6VDC motor draws 25mA, spins at 1100 rpm no load and stalls at 250mA. It's 2-3/8" long x 5/8" dia with a 3/16" dia x 1/4" 10-tooth sprocket. You can easily remove the sprocket if you just want to use the 5/16" dia x 1/16" shaft it's mounted on. The whole thing is mounted on a 7/8" dia plastic base with a 3/32" ID hole on a mounting wing.
