For engineers: Always drive this motor with a voltage source at or near 26V for optimal torque-speed flatness. Do not substitute a 12V-rated driver without recalculating current limits.
Used for driving belts on machines like the Ender-3, CR-10, and Ender-5. 3D Printer Z-Axis: Used for precise lead screw motion.
While a specific torque curve for the "26V10" is rare, the generalized typically offers a holding torque between 0.22 Nm to 0.34 Nm depending on current drive levels.

The BJ42D15-26V10 is a stepper motor, meaning it has two independent coils (phases). Typical values for this 34mm motor are:
For the BJ42D15-26V10 (Imax = 1.5A), the RMS current is:
The BJ42D15 26V10 is not a general-purpose motor. Its 26V winding makes it distinct. Here’s where it excels: For engineers: Always drive this motor with a
Typically a "D" shaft to prevent pulley or gear slippage.
Why did the manufacturer choose 26V? Most stepper drivers (A4988, DRV8825, TMC2209) operate at 12V or 24V. The sits in a sweet spot.
Commonly used in Creality or Prusa-style clones for precise filament extrusion. 3D Printer Z-Axis: Used for precise lead screw motion
For precise integration, it is recommended to adjust the driver's VREF (Voltage Reference) to ensure the current does not exceed 1.0A to prevent overheating.
The BJ42D15 motor is widely used in popular 3D printers:
