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.

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.

Our sturdy 24VDC 6A linear actuator motor with intermittent duty extends from 56-7/8" to 85-5/8" and has a 337-lb push. The extending shaft is 1-1/4" diameter and the U-joint at the end has a 7/16" ID hole for attaching. Use it to make something go up and down, or in an out. Like an awning, the door on your chicken coop, your holiday yard displays or something in your basement bar, man cave or she shed.

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.
