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.
