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.

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.
