Small motor with a gear. Marked 115V 60 Cycles. It turns freely, untested to a line voltage. 3 wires of black, red & brown, probably needs a capacitor to run. Gear is 13 teeth and removable. I measured black to red 170 ohms, black to brown 150 ohms, red to black 170 ohm, red to brown 320 ohms. It is 2 1/16" square. Check pictures. It's heavy, 2 lbs to ship.
