This technical profile provides the exact parameters verified from structural testing, vendor naming conventions, and mainboard configuration records.
Standard bipolar 4-lead configuration:
Always measure phase resistance before first power-on. If your motor reads ~12Ω, it is a different model (likely BJ42D15 12V10) and requires a different driver setup.
The motor follows the NEMA 17 standard mounting pattern, making it compatible with most universal brackets and extrusions. 42mm x 42mm Body Length: 34mm (excluding shaft) Shaft Diameter: 5.0mm (usually D-cut for pulley stability) Shaft Length: 20mm - 24mm (typical) Mounting Holes: 4 x M3 threaded holes Wiring and Phase Configuration bj42d15 26v10 stepper motor datasheet verified
The hunt for this motor's datasheet has become a common "quest" in the 3D printing community because Creality often uses multiple suppliers for the same part, such as Jkongmotor Keli Motor , leading to confusion over specific model numbers like the The Misidentification:

Disclaimer: Specifications may vary slightly between different batch manufacturers. Always measure the resistance and confirm with your motor's specific revision.
Tip: If you are replacing a motor and it spins in the wrong direction, you can reverse the direction by swapping the wires of a single coil (e.g., swap Blue and Red). Driver Configuration (Vref) The motor follows the NEMA 17 standard mounting
Understanding the naming convention is the first step to unlocking its specifications, as different versions cater to different electrical requirements. The model number BJ42D15-26V10 breaks down as follows:
