This torquey take-out 6-24VDC (12VDC nominal) motor draws approx 250mA no load, stalls at 7.2A and spins approx 5700 rpm. Measures 2" x 1-13/32" with a 3/4" x 1/8" flattened shaft and may have a setscrew-mounted coupler that resembles a router bit. Has prewired leads. Mabuchi part no. RS-545SH.

Attention robotics boffins: Here's a nice, powerful 12-24VDC Mabuchi brush motor with a gearbox and pulley attached. At its nominal 24DC, it spins 45rpm, draws 280mA no load, and stalls a 750mA. 7.5 in-lbs of torque and is rated for continuous duty. Has a 3/4" long x 5/16" flattened shaft with a 4-5/8" dia x 5/16" wide (3/16" ID) single-sheave pulley attached, with a matching O-ring. The gearbox measures 2-3/4" x 3" x 9-1/16". The motor measures 1-1/16"dia x 1-5/8" long and comes with 7" leads and a 2-pin Molex connector.

Don’t get too excited--we don’t have Tesla parts. But we do have this honey of a reversible 12VDC gear motor from a kid’s ride-able toy car. Spins approx 75 rpm, draws 800mA no load and stalls at 11.5A via a 1/4” dia gear that runs through a multi-gear box to a 6-spoked, 2-1/2” dia hub. Will run with as little as 3VDC with plenty of torque. Unit measures 7-3/4" x 3-3/4" x 4-3/4" in a teardrop shape, with a pair of 3” leads and a Molex connector.

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.

No funny business here, folks. This SKF ACTUATION SYSTEM linear actuator with a 730mm (28.74") stroke is rated for over 300 LB pushing or pulling. Draws 6 amps at 24VDC, plus it's fully reversible though it's designed for intermittent duty. Retracted length is 57" and overall size is 58" x 5" x 3-1/4". 11 seconds for a full stroke. Shaft diameter is 1-7/32" and has a 28mm clevis pin. Simple +/- lead hook-up. It's a real beauty weighing in at 11 lbs.

You know how your printer carriage (the thing with the ink cartridges) zips back and forth like the Road Runner? This is the motor that drives it. From Igarashi (part #599030-005) it’s a reversible DC gear motor rated for 22VDC, drawing 90mA no load and stalling at 750mA. Spins approx 115 rpm, but will run on as little as 6VDC. At 12VDC it draws 40mA, stalls at 390mA and spins approx 62 rpm. Measures 2-3/4" long x 1-5/16" dia at the gearbox with a flattened shaft and (3) 3/16" mounting holes. Gearbox is easily removable. Has 3” leads with a Molex connector and a boot at the back end.

From Maxon Motor, this nice and efficient gear motor is nominally rated at 36VDC, 152 rpm and draws 130mA, but will run with as little as 3V. At 12VDC, it spins approx 28 rpm, draws 75mA no load and stalls at approx 300mA. Measures 2” long x 15/16” dia with a 5/32” x 1/8” flattened shaft, with (3) 1/16” mounting holes on the face and 1-1/2” leads. Made in Switzerland despite not being chocolate or a watch.
