NEMA 17 Stepper Motor - 34mm, 28N-cm / 40oz-in

NEMA 17 Stepper Motor - 34mm, 28N-cm / 40oz-in

These are the stepper motors we use in our i3 printer kits. They're lightweight and compact, but still provide plenty of torque - we've found them to be perfect for everyday printer duty.

The motor's shaft has been ground flat, making it easy to get a good grip with a pulley, drive gear - or anything that uses a grub screw, really.

Another handy feature of these motors is their detachable leads - this makes installation a breeze, and it's easy to redo your wiring later if you'd like. We've had the included cables customised to plug straight into a RAMPS board, so installation of these motors is literally plug-and-play!

These motors provide an impressive 28N-cm of torque while running at under 1A! More than enough power to get the job done, and you don't have to run your stepper drivers at their limit - perfect!

We recommend these motors for X/Y/Z axis movement on a cartesian printer - for a delta printer, or for use in an extruder, you'd want to look at something with a bit more grunt like our larger 40mm motors (check the related items!).
