This little 6VDC Mabuchi motor (part #RE-36) draws only 20mA. Spins approx 3000 rpm and measures 1-1/4" x1-1/16" dia with a 3/8" long shaft and a 5/16" dia x 1/4" 8-tooth gear. Runs a tad a squeaky so CJ recommends a dab of machine oil before use.

We believe this permanent-magnet gear motor was made to power a car seat (move your butt!) but we could be wrong. Nice though, at 5" long x 2-1/2" square in a steel body with an aluminum head and a square 5/32" hollow shaft. Operates from 6-12VDC with a 12VDC nominal. Spins 500 rpm with 16 inch-pounds of torque and a 20A stall. Reversible and intermittent duty. Nice motor that could move lots of stuff for you.
