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.
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.
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!
From the back end of the short-lived Ford Freestar minivan ('04-'07) we've inherited the wiper motor assemblies with brake light attached. Units measure 16" long x 5-1/2" at their widest x 5-1/2" deep. Output shaft is 3/8" dia tapering down a 5/16" dia #20 pitch thread. Motor and lamp should both run off 12V. We haven't quite figured out how to make the gear motor run without ripping it apart, but we know you'll be up to the challenge. Ford part # 5F23-17D400-AB.
Our motor dude calls this DC reversible gear motor "very interesting." Rated for 3-24VDC with speed ranging from 75 to 654 rpm. The current draw is very low, 2.4mA no load and the highest readable stall current is 90mA. The motor itself is 1-11/16" long x 11/16" dia with a 7/16" long x 3/32" dia shaft with a 9mm (approx 3/8") single sheave, 2mm ID pulley on it. Motor is connected to a monodirectional drive assembly with some mystery circuitry glued to it. Feel free to discard this. Motor is German, gearhead and drive train are Swiss.
This little 6-12VDC gear motor (nominal voltage is 12VDC) spins at approx 60 rpm, draws 20mA no load and stalls at 1A. Measures 2-1/2" long x 1-5/16" dia, with a flattened 3/8" long x 3/16" dia shaft. A pair of 3mm terminals coming out of the back end.
This 12VDC motor, part of Johnson Electric's HC 970 Series, draws 500mA no load, spins approx 2900 rpm, has a 2.5A stall current. Measures 2-3/4" long x 2" dia with an 11/16" long x 1/4" dia shaft at each end.
It's not all chocolates and wrist watches in Switzerland; they also make mighty nice motors. This small, reversible inline DC gear motor from Maxon is nominally rated at 36VDC continuous duty; 140mA and 152 rpm. At 12VDC it spins approx 30 rpm. Measures 1-15/16" long x 15/16" dia with a 3/16" long x 1/8" dia flattened shaft and 1-1/4" leads. Stalls at 250mA.
This reversible 12VDC motor draws 500mA no load and stalls at 2.5A, spins at approx 2,000 rpm and measures 2-3/4" long x 1-7/16" dia with a 3/16" long x 1/8" dia shaft and threaded 3/32" mounting holes on one end with 1/4" long x 3/16" dia shaft on the other end.
