NEMA 17 Stepper Motor with 28cm Lead Screw - 40mm, 42N-cm / 60oz-in

NEMA 17 Stepper Motor with 28cm Lead Screw - 40mm, 42N-cm / 60oz-in

Instead of a regular motor shaft, these motors have an integrated leadscrew - just like the ones we carry in the shop. This means that you don't need to add a coupler to fasten the leadscrew in place, and ensures that the leadscrew is perfectly aligned with the motor. The usable length of leadscrew is approximately 28cm - similar to what you get with a 30cm leadscrew and a coupler.

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 42N-cm of torque while running at 1.5A! Perfect for moving a hefty X axis up and down in a Prusa build!

We recommend these motors for Z axis movement on a Prusa i3-style printer. We also carry motors without the integrated leadscrew - check the related items!
