The is a highly reliable, high-precision NEMA 17 hybrid stepper motor produced by Keli Motor Group . It is widely integrated into precision motion hardware, most notably serving as an OEM component for Creality 3D printers (such as the Ender and CR series), small-scale CNC machines, and medical equipment.
BJ42D15-26V10 is a NEMA 17 hybrid stepper motor manufactured by Hunan Keli Motor Co., Ltd. and is most commonly found as original equipment in Creality 3D printers bj42d15 26v10 stepper motor datasheet exclusive
Efficient between 1–1000 RPM, depending on the microstepping driver used. Applications: The is a highly reliable, high-precision NEMA 17
Note: There is common misinformation that these are 1.5A motors; however, verified data indicates they are rated for a lower current of 0.84A to 1.0A depending on the specific variant. NEMA 17 ( and is most commonly found as original equipment
The BJ42D15 26V10 is a hybrid stepper motor (42mm x 42mm faceplate). The nomenclature tells a story:
The motor is currently rated for 0.8A for proper torque and heat management in factory machines. However, some advanced communities have successfully driven them at peak currents nearing 1.5A with active cooling and specialized drivers (TMC2208/TMC2225). Operating at higher currents significantly increases the motor winding temperature (>60°C).
