Bj42d15 26v10 Stepper Motor Datasheet Exclusive ((full)) Jun 2026

Without an actual datasheet to refer to, let's decode the model number which might give some clues:

To use the BJ42D15-26V10 safely without it running excessively hot or lacking power, you must manually adjust the voltage reference (VREF) on your 3D printer's motherboard or standalone driver. Creality Ender 3 Stock Factory Vref · GitHub

The isn’t just another high-torque stepper—it features an optimized 26V, 10A/phase magnetic circuit design that delivers: bj42d15 26v10 stepper motor datasheet exclusive

is a highly reliable, high-precision NEMA 17 hybrid stepper motor manufactured by Kelimotor and widely deployed as an OEM component in Creality 3D printers . This exact variant is frequently found driving the high-precision axes (X, Y, or Z) on premium desktop fabrication machinery like the Ender and CR series.

[ P = I^2 \times R = (1.0)^2 \times 26 = 26 \text Watts per phase ] Without an actual datasheet to refer to, let's

Most stepper motor failures happen because engineers use the wrong driver configuration for the BJ42D15 26V10.

Because the "26V10" is not a standard retail model number, Keli's public datasheets do not list "BJ42D15-26V10". Instead, the closest public data correlates to the series, which lists a Rated Current of 1.5A and a Holding Torque of 210 mN.M. [ P = I^2 \times R = (1

The BJ42D15-26V10 follows standard NEMA 17 mounting patterns but features a compact body depth. 42.3mm x 42.3mm Body Length: 34mm (Standard "Short" Body) Shaft Diameter: 5mm (D-cut for slip prevention) Shaft Length: 20mm - 24mm (Varies by batch) Mounting Holes: M3 threaded, 31mm center-to-center 4.
