Combining data from the original equipment manufacturer (Keli Motor Group) and confirmed community documentation, here are the primary electrical and mechanical characteristics. bj42d15 26v10 stepper motor datasheet exclusive

BJ42D15-26V10 is a specialized NEMA 17 hybrid stepper motor manufactured by Hunan Keli Motor Co., Ltd.

To ensure optimal performance without overheating, users often adjust the stepper driver voltage (Vref). For a 0.84A rated motor on common Creality boards This 2-phase hybrid stepper motor utilizes a standard

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).

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. For a 0
