If you’ve found one of these in a bin of parts or are looking for a datasheet, you might have noticed that clear, official documentation is surprisingly hard to find. In this post, we are providing an exclusive breakdown of the specifications and practical applications for this specific motor, aggregating data from various industrial sources to create the datasheet you’ve been looking for.
The holding torque for a 34mm motor in this class is typically around 0.2 N·m (28 oz·in), which is modest compared to 40mm motors but sufficient for moving light gantries in 3D printers and engravers. More importantly, the is very low, allowing for smooth manual movement when the motor is not powered.
This exposé interprets BJ42D15-26V10 as a compact NEMA‑17 style stepper with a 15 mm stack and electrical characteristics suited for chopper drivers at ~26 V and ~1.0 A/phase.

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).
