Bj42d15 26v10 Stepper Motor Datasheet Exclusive ((hot)) — Instant & Hot

( I_RMS = I_max \times 0.707 = 1.5A \times 0.707 \approx 1.06A )

Due to the “26V10” designation being less common than 12V or 5V variants, counterfeit or mislabeled units exist.

The BJ42D15-26V10 is a 42x42x34mm NEMA 17 hybrid stepper motor by Keli Motor Group, commonly utilized in Creality Ender 3 printers for X, Y, or Z axis movements. It features a 1.8-degree step angle, 0.84A rated current per phase, and 2.86 kg·cm holding torque. For optimal performance on Creality boards, Vref should be adjusted to approximately 0.725A–0.75A to avoid overheating.
