MoTech NEMA 17 Stepper Motors

MoTech Stepper Motors

MoTech Motor offers premium quality Stepper Motors. HartSmart Products had these hybrid stepper motors custom made by MoTech to serve as either direct Modix printer drop-in replacements, or as general-purpose stepper motors for any 3D printer.

As a part of our customizations, all of these NEMA 17 stepper motors include:

  • 27mm shaft length
  • Full-length D-cut for a flat side the entire length of the 27mm shaft

Each motor also includes a 1 Meter long detachable cable with a motor connector at one end and a 4-pin Dupont connector on the other end.

NOTE:
For Modix X-Axis, Y-Axis, and Z-Axis motors select the 60mm version.
For Modix Extruder motors select the 40mm version. 
These are the exact models used by Modix in the original kits.
