Nema 14 Stepper Motors
A NEMA 14 stepper motor is a stepper motor with a 1.4 x 1.4 inch (35.6 x 35.6 mm) faceplate. Its size is only a coarse indication of its power. The NEMA 14 is a smaller and neater motor that was used on the Mendel prototype. Compared to a NEMA 17 it needs less space and typically weights less, so it's often seen in small printers, like the Huxley.
A NEMA 14 Stepper Motor is ideal for use in driving a Lead Screw assembly, Gear train, or Belt and Pulley mechanism.
NEMA 14 Stepper Motors for sale are available with a bipolar configuration as standard, and are available in 0.23A, 0.5A, and 1A varieties. Stepper Motors of this type are ideal for small-scale, high-precision applications. We can also customize Nema 14 Stepper Motor's winding to perfectly match voltage, current, and maximum operating speed to meet your requirements.
very strong for the weight, got it to optimize the weight of the extruder carriage. Note this is only really probably possible if you did what I did which is directly hob the shaft with a tap

Works perfectly for the Toranado geared 3D extruder. Shaft is slightly shorter so when mounting the pinion gear have it flush with the end of the shaft.

I bought this motor to drive a geared extruder on my 3D printer. It works great. The previous motor tended to overheat but this one remains cool even after several hours of printing.

No documentation. I've looked on line and can't find much. It does appear to work. I'm using it with an Arduino.
