Great for roboticists, too. It's a mighty-mite, this little 6VDC 45 RPM motor with a right-angle gearbox. Draws 13mA, no load, and stalls at 120mA. Output is through (2) double-flattened 1/4" dia x 3/16" long shafts on opposite sides of the white plastic housing, both with 1/16" dia center holes. Measures 1-7/8" x 7/8" overall. Gear ratio is 228:1.

Muffin fans, pay attention. You pick the "nice" 110 VAC 21W fan from Thermocool, measuring 4-3/4" square x 1-1/2" thick with an offset two-pin power connector, rated for 82-95 cfm and spinning at approx 2600 rpm, with five blades and 3/16" mounting holes at the corners (Mfr part # G12038HA1ST); or the "beastly" 110VAC 36W muffin fan from the same mfr, which blows up to 198 cfm at 2900 rpm and measures 6-3/4" x 6" tall x 2" thick with (2) power terminals on a removable shroud, 5 blades, 5/32" mounting holes on the corners plus a ground lug. Both UL.

This 3-6VDC motor operates optimally at 6VDC, draws 450mA no load, stalls at approx 2.4A and spins at about 13K rpm. Measures 2" long x 1-1/16" dia with a little 3/8" dia x 5/16" 12-tooth gear. Simple +/- leads are wired to a double jack that can easily be cut off or jumped. Leads are 14” long.

This 3-phase brushless 12VDC motor from Nidec draws 2.5A max through the red and black leads with what we think are coil taps, and Hall effect outputs through the other (4) leads. Measures 36mm (1.4") dia x 40mm (1.6") long with a 4mm (0.16") dia x 19mm (0.75") shaft with a removable cam. Includes a spec sheet.

This small reversible DC motor from JEI runs on 3-6VDC. At 6V it draws 350mA no load and stalls at 1.9A. Spins approx 1000 rpm and approx half that at 3V. Great for science fairs, hobbies and any kind of project that needs spinning. Measures 1-3/16" long x 7/8" dia with a 1/4" x 1/16" shaft and tiny contacts for power that you'd best solder.

You pick. The 4.5 VDC gear motor runs from 3-6V, spins 120 rpm, draws 80mA no load and stalls at 800mA. Measures 2-1/8" x 3/4" x 9/16" with a 3/8" x 1/8" flattened right-angle shaft. Rated for 20 oz/in of torque and has a 120:1 gearbox. The right-angle 4.5 VDC gear motor runs from 3-6V, spins 150 rpm, draws 130mA no load and stalls at 1.25A. Measures 1-7/16" x 1" x 1-5/16" in an L-shape with a  3/8" x 1/8" flattened shaft.

Our motorman, CJ, called this reversible 12-24VDC motor strange, mostly because it has the power contacts mounted on the face, bracketing the 11/16" x 1/8" mostly striated shaft, and has no mounting brackets. But that shouldn't stop a clever person like you. (Hint: it was probably made to fit into a sleeve of some sort.) At 12VDC, draws 100mA no load, stalls 850mA and spins approx 900 rpm; at 24VDC, draws 150mA, stalls 2.2A and spins approx 1800 rpm.  Measures 2-1/4" x 1-13/32" dia.

You’ve always wanted a tranquil water fountain on the grounds of your manor? Or at least on the table in your kitchen? This set will let you turn nearly any container into a soothing fountain. The 4” tall x 4” dia gray plastic pump cover has 3/4” notches in the bottom for a hose and water movement, and the removable top has a 3/8” ID center hole attached to a 2-1/2” long piece of 1/2” dia tube inside. It’s all made to conceal the included circulating pump, which moves 70 gal/hr @ 1 ft lift, and measures 2-5/8” x 1-1/2” x 2-1/4”. Runs on 24VAC, and has a 6-ft power cord with an in-line switch. Luxuriate in the soothing gurgle of water.

These are really geared reduction motors, but much smaller and of lower power. Often used to operate cams and switches in electrical circuits, or to drive displays, they can generally be operated in continuous applications if not heavily loaded. Most are about 2" dia. x 1-1/2" thick. You'll need a way of supplying 230VAC. 

And even more fan blades. Choose a white-plastic 5-blade or a black-plastic 4-blade, each approx 4" across with a 3/16" bore. Designed for clockwise rotation. No motor. Just blades. (But nice little blades.)

This 12VDC gear motor is a new reversible double-shafted automotive seat motor that was never installed in the auto. Draws 1.3A no load, stalls at approx 9.5A and spins 2,500 rpms. Output is through 1/8" sq x 5/8" deep ports at the front and back of the housing (we'll include (2) short, square shafts to get you started). Housing measures 4-5/8" long x 1-29/32" dia with (2) shrouded power terminals at one end and (2) 3/16" dia spurs at the other. Overall, it's 5" x 2-3/4" across.

Alas, these animal toys are dead. The giraffes, elephants, zebras, boxer-type dogs (who knows?) won't work, but they'll have nice little DC motors inside, plus battery boxes and plastic gearboxes and maybe camshafts, just waiting for someone with a small screwdriver to disassemble them and give the parts and pieces a whole new life, perhaps in a clever science fair project.

This NOS 12VDC 1A 3-coil brushless servo motor with 36 steps per revolution was for a printer, maybe. Or a scanner, maybe. Whichever, it's mounted on a 2-1/2" x 2" plate with a 3/4" long shaft with a 5/8" dia rubber wheel out one side and a 15-tooth, 2" dia plastic sprocket on the side with the leads. The white lead feeds a Hall effect sensor, then ground, +5V control, and then the three coil leads  Samsung P/N 02914900.

These 3-12VDC replacement window motors from Chrysler spin approx 120 RPM, draw 3.3A no load and stall at 10.3A. Rated 12VDC nominal. Output is through a 23/32" dia x 5/16" 32-tooth gear at a right angle to the housing, which has a trio of 3/8" double-keyed mounting holes. Measure 7-1/4" x 5" x 1-1/2" thick, with two-pin connectors. Passenger side part #128001051.

Brand-spankin' new power window replacement motors for VW Jettas. Draw 3A no load at 12VDC and spin approx 120rpm. Output is through a 23/32" dia x 3/8" 32-tooth plastic gear, and the motors are 7-1/4" x 5" x 1-3/4" overall. (Wethinks usable in either front or rear doors.)

This small 1-1/2-3VDC reversible hobby motor from Mabuchi draws 25mA no load and stalls at 90mA at 3VDC. Spins at 6900 rpm. Measures 1-3/16" long x 15/16" dia with a 1/4" shaft and a 3/16" dia x 1/8" gear. Power through marked recessed ports on the back.

Our 120VAC 2.5W aquarium aerator pump is rated for 3L per minute and has an adjustable flow control. Outlet takes a 3/32" ID tube. Unit measures 5" x 2-9/16" x 2-1/8" with an 80" cord

Our Technical Identification Division (CJ) says this is most likely a take-out timer motor from a washing machine. "Probably." Measures just under 2" dia x just under 1" thick, not counting little wings with 5/32" mounting holes and a 10-tooth 5/32" gear. Draws 3W at 115VAC (it has leads but you supply the cord) and spins appx. 8.5RPM. Intermittent duty.
