MoTech Motor offers premium quality closed loop Stepper Motors. HartSmart Products had these closed loop stepper motors custom made by MoTech to ensure they will work well in most 3D printers. 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
NOTE: Closed Loop Steppers will require a Closed Loop Stepper Driver, and are not drop-in replacements for Open Loop Stepper Motors.
