These small timing motors draw 3W and are just under 2" dia x approx 3/4" thick with mounting wings that have (3) 1/8" holes. You pick: the 11VAC motor that spins 1 rpm CCW with a 3/4" long shaft with an attached 3/4" dia x 1/4" thick 16-tooth gear, 24-pitch and 20-degree pressure angle; or the 24VAC motor that spins 1 rpm CW and has an 8-tooth, 5/16" dia x 11/32" plastic gear, 32-pitch and 20-degree pressure angle.

This silver 9VDC air pump with a clear pumping assembly is 3-1/2" x 2” x 3” with a piston behind the clear plastic on one end. Both the 7/16” intake and ¼” output are on one side of the assembly. We couldn't find exact info on it, but it moves air at a moderate rate. Two 3/16” spade terminals on it’s motor side and will work for a short time on a 9 volt battery.

This bipolar, 2-phase stepper motor from Shinano Kenshi Corp (SKC) draws 500mA at 9VDC with a 0.9 deg./step. Coils are brown/orange and red/yellow. Measures 1-7/16" dia x 1/2" with a 4" long, 3/8" threaded shaft, and mounting wings with 1/8" holes.

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.

…with this nice little gear motor. Nominally rated for 24VDC and draws .2A with no load, this motor spins clockwise at 24RPM. The motor measures 2” X 1-1/8” and comes on a mounting bracket, but that’s removable. Shaft size is 3/16” dia. by 1/2” long, making the whole shebang measure 4" x 1-3/4" x 2". Rated for intermittent duty. Made in Japan, arigatou.

This little L-shaped low-pressure piston-and-diaphragm air pump has a 7/32" OD inlet and an 11/32” OD x 9/32” ID outlet, and is attached to a Mabuchi RK-555PH 12VDC motor that draws 100mA no load, stalls at 4.3A, and spins approx 3500 RPM. Measures 4" x 1-5/8" x 3" with 2” leads.

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. Can you say Science Fair?

Because it’s a new take-out fan motor from Welling Service Co., made for air conditioner-humidifiers. Rated for 115VAC, 16W, spins approx 1400 rpm via a 2-1/2” x 5/16” threaded shaft which will most likely have a nut on the end. Has 12” long leads, (2) of which are for a 6uF capacitor (not included).

The wall-mount cases measure 7-3/4" x 3-1/2" x 3-1/8” in cream plastic, with a cover that comes off to reveal a dandy 1.5V motor with a 5-blade fan, and terminals for a D cell battery. Motor is 1” dia x 1” long, shaft is 1/16” dia x 3/8” long, and fan blade is 2-3/8” dia.

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.

Of course you’re not, but you might like squirrel-cage fans like we do. If so, this take-out, cream-colored ABS plastic squirrel-cage blade is for you. Originally from portable AC units, they measure 6-3/4" dia x 3-3/8" across with a flattened 5/16" ID bore and a 3/4" shaft that extends 7/8” into the cage. Could be re-rigged for a gerbil wheel.
