These brand-spanking new 12VDC motors are made to move automobile seats but are willing to change. They spin at approx 190 rpm, draw 1.5A no load, and stall at approx 25A. Threaded shaft is at a right angle and is 4-1/8" x 7/16". Shaft thread is non-standard, so treat it as a smooth shaft and mount pulley or gear with a setscrew. Measures 5-5/8" x 2-1/2" x 2-1/2" overall, not counting the shaft, and has power terminals opposite the gearbox with (2) 1/4" mounting holes opposite the shaft. Shaft Thread 7/16"-8 ACME thread w/M6x1 LH at end

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 9/16". The motor measures 1-1/16"dia x 1-5/8" long and comes with 7" leads and a 2-pin Molex connector.

Even this 7/8" x 2-1/8" Hennkwell ball bearing reversible gear motor is ball bearings. Fletch could have told you that. Operates from 6-24VDC (optimal being 24VDC, turning at 142 rpm). Item number PZ22GR9120R-084BBH. Has a (2)-shafted front shaft (6mm dia x 14mm length), and a rear shaft with a 2mm dia x 11.2mm length. Also has (4) front-threaded mounting holes and solder lug terminals. Made in Taiwan.

…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.

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.

These small, new motors for oil-heater louvered doors were made for, but never installed in, WWII-era B-17s and B-24s. High torque, low rpm, these collectible 24VDC 1.5A motors measure 5-1/8" long x 3-1/2" dia on the shaft side and 2-3/8" dia on the other end, in a blunted bullet shape. The 15-tooth output shaft is 3/4" long x 1/2" dia, centered on the large end with a trim screw offset for some speed control, and a 4-pin Amphenol connector. Rated at 24VDC but will operate between 12-26VDC. These are of particular interest to us because the sample, at least, was manufactured right down the road from us in Rockford, Illinois, by the Barber-Colman Company!
