BJ42D15-26V10

The is a high-precision, 2-phase hybrid stepper motor primarily manufactured by Hunan Keli Motor Co. and commonly used in Creality 3D printers like the Ender 3 series . While often referred to as a "Creality 42-34 motor," the "BJ" prefix indicates its origin from Keli Motor. Technical Specifications Summary

Performance & control implications

Verified Color Code (Factory Standard):

1. Desktop 3D printer extruder drive – Low torque need, high precision, 26V matches common PSU.
2. Microscope focus stepper – Low inertia, smooth motion with 1/32 microsteps.
3. Small CNC pen plotter – Light load, high speed between waypoints.
4. Lab syringe pump – Accurate holding torque at low speed.
