Because the official datasheet is often considered a proprietary document of the OEM (Keli Motor Group), the following data has been extrapolated from identical BJ42D series specifications and reverse-engineered from community testing.
The most frequent mistake when replacing a BJ42D15 motor is ignoring the :
Stepper motors are type of electric motors that rotate in discrete steps, allowing for precise control over position, speed, and torque. They are widely used in applications that require accurate positioning, such as robotics, CNC machines, and medical devices.
The 0.8A to 1.5A current capability of this motor dictates which stepper drivers are appropriate. bj42d15 26v10 stepper motor datasheet exclusive

5mm (D-type shaft for secure gear/pulley mounting) Shaft Length: 22mm Mounting Holes: M3 threaded, 31mm apart Wiring and Phase Configuration
Exceeding this limit will rapidly overheat the motor, risk degaussing the internal magnets, or melt plastic mounts on your machine. Input Voltage : Maximum DC . While the motor can function on systems, supplying Because the official datasheet is often considered a
For procurement, ensure that your supplier provides the original badge—clones often substitute 18Ω windings, which will overheat under true 26V drive. Use this exclusive technical guide as your purchase validation checklist.
Based on the series standards from the Keli Motor Group and community data on the GitHub Creality Vref database , the motor follows these parameters: Type: 2-Phase Hybrid Stepper Motor. Step Angle: 1.8∘1.8 raised to the composed with power (200 steps per revolution). Rated Current: Approximately 0.84A .
No. The 26V10 variant has a higher winding resistance. Using a 24V08 driver would under-current this motor, leading to missed steps. While the motor can function on systems, supplying
is a NEMA 17-sized bipolar stepper motor commonly used in precision automation, specifically within the paper-handling mechanisms of photocopiers and laser printers.

Without an actual datasheet to refer to, let's decode the model number which might give some clues:
Many makers mistakenly configure this NEMA 17 hybrid stepper motor using generic 1.5A profiles, leading to overheating, missed steps, or driver damage. This datasheet analysis settles the confusion by delivering the verified technical metrics directly from factory firmware frameworks and physical hardware parameters.
