NEMA-17 2.4A 0.9'/step 400step/rev 48mm length

NEMA 17 stepper motors are used in almost all the Reprap 3D Printers and small CNC machines.  

These motors have a higher step count compared to the normal Stepper Motors. Meaning you get a more accurate print out of your 3d printer

This 48mm motor is ideal to drive the X and Y axis of a 3D printer.

This is a high torque, bi-polar, 4-wire stepper motor and comes with pig tail leads. 

Colours of leads are Black,green,blue,red
